I. From the Perspective of the Product Itself
(I) Specification Parameters
The specification parameters of the Flexible 3-
Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable are the core basis for the product's performance and applicable scenarios. Each parameter has undergone precise calculation and strict control to ensure the product operates stably in various power transmission scenarios.
In terms of conductor specifications, the cable is clearly marked as 3X1.5mm², which means the cable contains 3 independent core wires inside, and the cross-sectional area of each core wire conductor is 1.5mm². As a key indicator for measuring the current-carrying capacity of the cable, the 1.5mm² specification is scientifically calculated to meet the power transmission needs in conventional scenarios. According to professional testing, under the rated ambient temperature, the safe current-carrying capacity of a single 1.5mm² OFC conductor can reach 10 - 16A (the specific value varies slightly depending on the laying method and ambient temperature). When the
3 Core Wires work together, they can realize synchronous multi-circuit power transmission. This not only avoids the trouble of laying multiple single-
Core Cables in parallel in complex circuits but also effectively reduces the overall resistance loss of the line, ensuring the efficiency of power transmission.
In terms of cable outer diameter and weight, the product also has precise control. Considering the space requirements during installation and wiring, the overall outer diameter of the cable is optimized. On the premise of ensuring the thickness of the insulation layer and sheath layer and the safety performance, the outer diameter is reduced as much as possible. Test data shows that the outer diameter of the cable is approximately 8 - 10mm (excluding connectors). This size allows it to easily pass through narrow spaces such as wall-embedded pipes and
Internal Wiring channels of equipment, greatly improving the
Flexibility of installation. In terms of weight, the weight of the cable per 100 meters is about 12 - 15kg. The lightweight feature not only reduces the load during transportation but also makes it easier for construction workers to carry and lay, improving construction efficiency.
The insulation and sheath parameters are important links to ensure the safe operation of the cable. The insulation layer of the cable is made of high-quality polyvinyl chloride (PVC) material, with an insulation thickness of 0.8 - 1.0mm. This thickness has passed strict voltage withstand tests and can effectively prevent current leakage under the rated voltage, avoiding the risk of electric leakage caused by too thin insulation layer. The insulation resistance is more than 100MΩ (at 20℃), which is much higher than the industry standard, further ensuring the electrical insulation performance of the cable. The sheath layer is also made of flame-retardant polyvinyl chloride (PVC) material, with a thickness of 1.0 - 1.2mm. In addition to good wear resistance and aging resistance, it can also play a flame-retardant role when encountering open flames. Its oxygen index is ≥32%, which meets the requirements for flame-retardant cables in GB/T 19666 - 2019 "General Specification for Flame-Retardant and
Fire-Resistant Wires, Cables or Optical Cables", adding an important guarantee for the safe use of the cable.
In terms of electrical performance parameters, the cable performs excellently. The rated voltage is 450/750V, and this voltage level is suitable for low-voltage power distribution systems, covering most power needs in civil, commercial and small industrial fields, such as household circuits, office equipment power supply, and small industrial instrument power supply. The DC resistance of the cable (at 20℃) is ≤12.1Ω/km, which is much lower than the standard value of ordinary
Copper Cables. Low resistance means less loss of current during transmission, which can effectively reduce power waste, reduce line heating, and extend the service life of the cable. In addition, the cable also has good voltage withstand performance. It can withstand a 1-minute voltage withstand test under 1500V AC voltage without breakdown or flashover, fully verifying its safety and reliability when operating under the rated voltage.
(II) Characteristic Applications
Relying on its unique performance advantages, the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable demonstrates broad application value in many fields and becomes an ideal choice for power transmission in different scenarios.
In the civil field, the cable has a wide range of application scenarios, covering almost all types of power needs in family life. In the renovation of household circuits, it is the preferred cable for connecting socket circuits and lighting circuits. For socket circuits, household appliances such as refrigerators, washing machines, televisions, and air conditioners in the home need to obtain power through sockets. The 3-core design of the cable can correspond to the live wire, neutral wire, and
Ground Wire respectively, meeting the three-phase power supply needs of household appliances and ensuring electricity safety. At the same time, the excellent electrical conductivity of the OFC conductor can stably supply power to household appliances, avoiding appliance failures caused by unstable voltage. In the lighting circuit, whether it is the main lamp in the living room and bedroom or the auxiliary lighting in the kitchen and bathroom, the flexibility of the cable allows it to easily adapt to the complex wiring environment inside the ceiling and walls. It can be laid smoothly even in narrow lamp troughs or wiring pipes, and the flame-retardant feature can effectively reduce the risk of fire caused by short circuits in the lighting circuit. In addition, for some high-power household appliances that require separate wiring, such as wall-mounted air conditioners and electric water heaters, the cable can also be used as a dedicated power cable. Its 1.5mm² conductor cross-sectional area can meet the current needs of such household appliances, ensuring the stable operation of the equipment.
The commercial field has higher requirements for the stability, safety, and durability of cables, and this cable can just meet these needs. In office buildings, a large number of office equipment such as computers, printers, copiers, and projectors need to operate at the same time. The
Multi-Core structure of the cable can realize parallel power transmission of multiple devices, avoiding line confusion. Its low-resistance feature can reduce power loss, ensuring that office equipment will not be affected by voltage fluctuations and affect work efficiency during long-term operation. In places such as shopping malls and hotels, the lighting system is an important infrastructure. The flame-retardant performance of the cable can reduce the risk of fire caused by lighting line failures, ensuring the safety of places with dense people. At the same time, its flexibility allows it to adapt to the complex wiring environment of shopping mall ceilings and hotel corridors, and cooperate with various lighting fixtures to achieve a beautiful and safe wiring effect. In addition, security equipment in commercial places, such as surveillance cameras and access control systems, has extremely high requirements for the stability of power supply. The OFC conductor of the cable has good oxidation resistance and corrosion resistance, which can stably supply power to security equipment for a long time, avoiding the paralysis of the security system caused by line failures.
The working conditions in the industrial field are complex and diverse, which put forward severe tests on the adaptability and reliability of cables. However, this cable also performs well in some small industrial scenarios. In terms of small industrial equipment, such as small machine tools, blowers, water pumps and other equipment, the internal wiring space is limited, and the equipment may generate a certain amount of vibration during operation. The flexibility of the cable allows it to be flexibly wired inside the equipment to adapt to the structural layout of the equipment. At the same time, the wear-resistant and aging-resistant sheath layer can resist the friction and environmental erosion generated during the operation of the equipment, extending the service life of the cable. In the field of instruments and meters, various testing instruments and control instruments have high requirements for the accuracy of power transmission. The low-resistance feature of the cable can reduce the interference during current transmission, ensuring the measurement accuracy and control accuracy of the instruments and meters. Its flame-retardant performance can also provide safety guarantees for the laboratories or workshops where the instruments and meters are located, avoiding accidents caused by cable failures.
The rapid development of the new energy field has brought new application space for the cable. In small solar energy equipment, such as household solar street lights and small solar power banks, it is necessary to transmit the electrical energy generated by the solar panels to energy storage devices or electrical equipment. The OFC conductor of the cable has excellent electrical conductivity, which can efficiently transmit electrical energy, reduce the loss of electrical energy during transmission, and improve the energy utilization rate of solar energy equipment. At the same time, its aging resistance can adapt to harsh outdoor environments such as sun and rain, ensuring the long-term stable operation of the equipment. In terms of energy storage equipment, such as small household energy storage batteries and portable energy storage power supplies, the cable can be used as a connection line between the energy storage equipment and external electrical equipment. Its safety performance and stability performance ensure the safety of power transmission during the charging and discharging process of the energy storage equipment, providing strong support for the promotion and application of new energy.
(III) Material and Style
1. Material Selection
The Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable pursues excellence in material selection. Each type of material is carefully selected and tested to ensure that the product meets high industry standards in terms of performance, safety, and durability.
The
Conductor Material adopts oxygen-free copper (OFC), which is the core advantage of the cable in terms of electrical conductivity and service life. Oxygen-free copper is made by removing oxygen and other impurities from copper materials through a special smelting process, and its purity can reach more than 99.95%. Compared with ordinary electrolytic copper, the crystal structure of oxygen-free copper is more uniform, and the internal impurity content is extremely low, which significantly improves its electrical conductivity. The resistivity of ordinary electrolytic copper is about 0.0172Ω·mm²/m (at 20℃), while the resistivity of oxygen-free copper can be reduced to below 0.0165Ω·mm²/m (at 20℃). Lower resistivity means less loss of current during transmission, which can effectively improve the efficiency of power transmission, especially in long-term and high-current transmission scenarios, this advantage is more obvious. At the same time, the oxidation resistance and corrosion resistance of oxygen-free copper are much better than those of ordinary copper materials. In humid, high-temperature or corrosive gas environments, the surface of the oxygen-free
Copper Conductor is not easy to form an oxide layer or corrosion layer, which can effectively avoid problems such as increased line resistance, decreased electrical conductivity, and even line failures caused by conductor oxidation and corrosion, significantly extending the service life of the cable.
The insulation layer material is made of high-quality polyvinyl chloride (PVC). This material has good electrical insulation performance, chemical corrosion resistance, and processing performance, and is an ideal choice for the insulation layer of wires and cables. To ensure the insulation effect, the selected polyvinyl chloride material is modified through a special formula, and additives such as antioxidants and stabilizers are added to further improve the aging resistance and thermal stability of the material. Within the normal operating temperature range (-15℃ - 70℃), the insulation layer can maintain good flexibility and insulation performance, without cracking, hardening and other phenomena due to temperature changes, effectively preventing current leakage and ensuring electricity safety. At the same time, the polyvinyl chloride material also has a certain degree of oil resistance and solvent resistance. When it comes into contact with oil stains and a small amount of chemical solvents, it will not dissolve or deform, ensuring the integrity and insulation performance of the insulation layer.
The sheath layer material also uses flame-retardant polyvinyl chloride (PVC). On the basis of having the advantages of ordinary polyvinyl chloride materials, flame retardants are added to make the sheath layer have excellent flame-retardant performance. The selected flame retardant is an environmentally friendly halogenated flame retardant (or halogen-free flame retardant, selected according to customer needs). When encountering an open flame, the flame retardant can quickly decompose to produce flame-retardant gas, inhibit the combustion and spread of the flame, and at the same time form a carbonized layer on the cable surface to block heat transfer and oxygen contact, effectively slowing down the burning speed of the cable. After the fire source is removed, the cable can self-extinguish quickly to avoid re-ignition of the flame, greatly reducing the risk of fire accidents expanding. In addition, the polyvinyl chloride material of the sheath layer also has good wear resistance and impact resistance. During the laying, handling or use of the cable, it can effectively protect the internal core wires and insulation layer, avoiding cable damage caused by external impact and friction.
2. Style Design
The cable takes practicality and convenience as the core in style design, fully considering the installation and use needs in different scenarios, and showing unique design advantages.
In terms of appearance style, the sheath layer of the cable adopts a smooth and flat surface design, and the color is mainly black or gray (other colors can be customized according to customer needs). This design not only makes the cable look simple and elegant, easy to identify and distinguish, but also can effectively reduce the adhesion of dust and dirt, facilitating daily cleaning and maintenance. At the same time, the smooth surface can reduce the friction resistance with the contact surfaces such as pipes and walls during the laying process, making it easier for the cable to pass through narrow channels and reducing the construction difficulty.
In terms of structural style, the cable adopts a tightly stranded 3-core structure. The 3 core wires are stranded together according to a certain stranding pitch. This structural design can effectively improve the flexibility and tensile performance of the cable. The size of the stranding pitch is carefully designed to ensure the flexibility of the cable and avoid problems such as loose core wires and displacement caused by too loose stranding. At the same time, the tight stranded structure can also reduce the interference of external electromagnetic interference on the internal signal (or power) transmission of the cable. This advantage is more obvious especially in scenarios where power and control signals are transmitted at the same time. In addition, a filling layer (for some specification products) is also set between the core wires and the sheath layer. The filling layer is made of polypropylene mesh fiber or other flexible filling materials, which can make the structure of the cable more round and tight, prevent the core wires from shaking inside the sheath layer, and at the same time play a certain buffering role, reducing the impact of external forces on the core wires and further protecting the core wires and insulation layer.
(IV) Production Process
The production process of the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable strictly follows industry standards and the enterprise's internal quality control system. Each production process is carefully designed and strictly monitored to ensure stable and reliable product quality.
1. Conductor Manufacturing Process
Conductor manufacturing is the first key process in cable production, which directly affects the electrical conductivity of the cable. The conductor of the cable uses oxygen-free copper rods as raw materials. First, the oxygen-free copper rods are drawn into
Copper Wires with a diameter that meets the requirements through the wire drawing process. During the wire drawing process, a high-precision wire drawing machine is selected, and a multi-pass continuous wire drawing method is adopted. Each wire drawing process strictly controls the wire drawing speed, die size and cooling method to ensure that the diameter of the copper wire is uniform, the surface is smooth, and there are no defects such as scratches and cracks. The drawn copper wire needs to undergo annealing treatment. The annealing process is carried out under the protection of inert gas. By accurately controlling the annealing temperature (about 400 - 500℃) and holding time, the internal stress generated in the copper wire during the wire drawing process is eliminated, the crystal structure of the copper wire is improved, and its electrical conductivity and flexibility are further enhanced. According to the cross-sectional area requirement of the 1.5mm² conductor, the annealed copper wires are stranded into strands according to a certain stranding process. During the stranding process, the stranding pitch and tension are strictly controlled to ensure that the
Stranded Conductor has a compact and round structure and uniform electrical conductivity.
2. Insulation Extrusion Process
The insulation extrusion process is a key process for coating the insulation layer on the conductor surface, which is crucial to the insulation performance of the cable. This process adopts the extrusion molding process, and a special wire and cable extruder is selected to uniformly coat the molten polyvinyl chloride
Insulation Material on the conductor surface. Before extrusion, the polyvinyl chloride material is first dried to remove the moisture in the material, avoiding the generation of bubbles inside the insulation layer and affecting the insulation performance. During the extrusion process, the extrusion temperature (barrel temperature is about 160 - 190℃, die head temperature is about 180 - 200℃), extrusion speed and traction speed are strictly controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, and no defects such as eccentricity, pinholes, and impurities. After extrusion, the insulation layer immediately enters the cooling water tank for cooling and shaping. The cooling water temperature is controlled at 20 - 30℃. Through uniform cooling, the structure of the insulation layer becomes more stable, avoiding problems such as deformation and cracking of the insulation layer caused by uneven cooling. The cooled
Insulated Core wires need to undergo performance tests such as insulation thickness, insulation resistance, and voltage withstand. Only the insulated core wires that pass the test can enter the next process.
3. Cabling Process
The cabling process is the process of stranding 3 insulated core wires to form a cable core, which has an important impact on the structural stability and flexibility of the cable. During the cabling process, a special cabling machine is selected to strand the 3 insulated core wires according to a certain stranding direction and stranding pitch. To ensure that the cable core structure is compact and round, filling materials (such as polypropylene mesh fiber) will be added inside the cable core as needed during the stranding process. The dosage and distribution of the filling materials are accurately calculated to ensure the roundness and stability of the cable core. At the same time, the cabling tension is strictly controlled to avoid damage to the insulation layer caused by excessive stretching or extrusion of the insulated core wires during the stranding process. The cabled cable core needs to undergo appearance inspection and structural size measurement to ensure that the stranding quality of the cable core meets the requirements. Any cable core with uneven stranding, loose filling materials, or damaged insulation layers will be returned for rework to avoid affecting the subsequent sheath extrusion process.
4. Sheath Extrusion Process
The sheath extrusion process is the step of coating the sheathed layer on the surface of the cabled core, which is a critical link to ensure the cable's safety performance and durability. Similar to the insulation extrusion process, this step differs in material selection and process parameter control. The sheath layer uses flame-retardant polyvinyl chloride (PVC) material, which also undergoes drying treatment before extrusion to remove moisture from the material—this is essential to prevent bubbles from forming inside the sheath layer, which could compromise its structural integrity and flame-retardant effect.
During extrusion, the process parameters are adjusted according to the characteristics of the flame-retardant PVC material. The barrel temperature is controlled at approximately 165 - 195℃, and the die head temperature is set to 185 - 205℃. These temperature ranges are optimized to ensure the flame-retardant PVC material is fully melted and uniformly coated on the cable core surface, while avoiding material degradation due to overheating. The extrusion speed and traction speed are synchronized precisely to ensure the sheath layer has a uniform thickness (consistent with the 1.0 - 1.2mm specification) and a smooth surface, free from defects such as eccentricity, impurities, or surface cracks.
After extrusion, the
Sheathed Cable immediately enters a cooling water tank for cooling and shaping. The cooling water temperature is maintained at 20 - 30℃, and the cooling time is controlled based on the cable diameter to ensure the sheath layer is fully solidified and adheres tightly to the cable core. Once cooled, the cable undergoes a series of inspections for the sheath layer, including thickness measurement, outer diameter verification, and flame-retardant performance testing. For flame-retardant performance testing, samples are taken from each production batch to conduct vertical burning tests in accordance with GB/T 19666 - 2019. Only cables that pass these tests—i.e., those that self-extinguish within 30 seconds after the fire source is removed and do not cause the spread of flame to the upper part of the sample—are allowed to proceed to the next process.
5. Finished Product Inspection and Pre-Packaging Process
Finished product inspection is the final quality control checkpoint in the cable production process, designed to ensure all outgoing products meet the required standards. This inspection covers multiple dimensions, including appearance, structural dimensions, electrical performance, mechanical performance, and flame-retardant performance.
Appearance Inspection: Inspectors visually check the cable's sheath layer for smoothness, ensuring there are no scratches, cracks, bubbles, or uneven coloration. Any cable with obvious surface defects is marked for rework or rejection.
Structural Dimension Inspection: Using precision measuring tools (such as a caliper and a laser diameter gauge), the cable's outer diameter, sheath thickness, core wire spacing, and overall length are measured. These dimensions must align with the product's design specifications—for example, the outer diameter must be within the 8 - 10mm range (excluding connectors), and the sheath thickness must not be less than 1.0mm.
Electrical Performance Inspection: This includes insulation resistance testing, voltage withstand testing, and DC resistance testing. The insulation resistance test uses a megohmmeter to measure the resistance between the conductor and the sheath layer at 20℃, requiring a minimum value of 100MΩ. The voltage withstand test applies a 1500V AC voltage between the conductor and the sheath for 1 minute, with no breakdown or flashover allowed. The DC resistance test measures the conductor's resistance per kilometer at 20℃, ensuring it does not exceed 12.1Ω/km.
Mechanical Performance Inspection: Tensile strength and elongation at break tests are conducted on the sheath and insulation layers. The tensile strength of the PVC material must be at least 12MPa, and the elongation at break must be no less than 150%, ensuring the cable can withstand moderate mechanical stress during installation and use without damage.
Only cables that pass all these inspections are transferred to the pre-packaging process. This process involves cutting, coiling, and labeling the cables. Based on customer orders, the cables are cut into specified lengths (e.g., 100 meters/roll or 200 meters/roll) using a high-precision cutting machine, ensuring clean, burr-free cuts. The cut cables are then coiled onto dedicated cable reels (made of high-strength cardboard or plastic) using an automatic coiling machine. The coiling tension is carefully controlled to ensure the cable is wound tightly and neatly, with no loose or overlapping sections. Finally, a product label is affixed to each cable reel, containing key information such as the product name, specification (3X1.5mm²), length, production date, batch number, execution standard (GB/T 19666 - 2019), and manufacturer’s name and contact information. This labeling ensures traceability and helps customers quickly identify and verify the product.
II. From the Perspective of General Product Information
(I) Packaging
The packaging of the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable is designed to prioritize product protection, transportation convenience, and storage safety. A multi-layer packaging structure is adopted to ensure the cable remains undamaged from the production workshop to the customer’s hands, even during long-distance transportation or prolonged storage.
1. Inner Packaging
The inner packaging directly protects the cable surface, preventing friction, dust contamination, or minor impact damage during transportation and storage. For coiled cables, the inner packaging uses high-strength polyethylene (PE) film, which is wrapped tightly around the cable reel. PE film offers excellent flexibility, wear resistance, and moisture resistance—its tight fit with the cable surface forms a barrier against dust, water vapor, and small debris, ensuring the cable remains clean and dry. Additionally, the PE film’s transparency allows customers to visually inspect the cable’s appearance without opening the packaging, facilitating quick quality checks upon receipt.
For bulk cable orders (e.g., large rolls of 1000 meters), the inner packaging may also include a layer of non-woven fabric between the PE film and the cable. The non-woven fabric adds an extra cushioning layer, reducing friction between the cable layers during unwinding and preventing surface scratches caused by direct contact with the PE film. This is particularly important for preserving the integrity of the flame-retardant sheath layer, as even minor scratches could compromise its flame-retardant performance.
2. Outer Packaging
The outer packaging is designed to withstand external pressure, impact, and environmental factors during transportation. Two main types of outer packaging are used, depending on the order quantity and transportation method:
Cardboard Drum Packaging: For standard orders (e.g., 100 - 500 meters per roll), the cable reels are placed inside cylindrical cardboard drums. These drums are made of multi-layer corrugated cardboard with a compressive strength of at least 1500N, ensuring they can withstand the weight of stacked packages during storage and transportation. The inner wall of the drum is lined with a waterproof PE film to prevent moisture intrusion in humid environments (e.g., sea freight or rainy weather). The drum lid is sealed with strong adhesive tape and reinforced with metal buckles to prevent accidental opening during transit. Each drum is labeled with the same product information as the inner cable reel, along with handling instructions (e.g., “Do Not Stack Over 3 Layers” or “Keep Dry”).
Wooden Crate Packaging: For large-volume orders (e.g., over 1000 meters) or shipments to regions with harsh transportation conditions (e.g., remote areas with rough roads), wooden crates are used. The crates are made of high-quality pine wood that has been treated for insect resistance and moisture proofing, complying with international shipping standards (e.g., ISPM 15 for wood packaging). The internal structure of the crate is customized to fit the cable reels, with foam padding placed between the reels and the crate walls to absorb shocks and prevent movement during transit. The crate is sealed with metal hinges and locks, and the exterior is marked with clear shipping labels, including the consignee’s address, contact information, and warning signs (e.g., “Fragile” or “Handle With Care”).
3. Special Packaging for Custom Orders
For customers with specific packaging requirements (e.g., small-length samples, color-coded packaging for different projects, or branding needs), custom packaging solutions are available:
Sample Packaging: Small-length samples (e.g., 1 - 5 meters) are packaged in transparent plastic tubes with labeled caps. The tubes protect the sample from damage and allow customers to inspect the cable’s flexibility and appearance. Each tube is accompanied by a product data sheet that summarizes the cable’s key specifications and performance parameters.
Color-Coded Packaging: For customers who need to distinguish cables for different projects or circuits, the outer packaging can be customized with color-coded labels or sleeves (e.g., red for power circuits, blue for lighting circuits). This helps streamline on-site installation and reduces the risk of wiring errors.
Branded Packaging: For business customers or distributors, the outer packaging can include the customer’s logo, brand name, or promotional messages. This is done through custom-printed cardboard drums, wooden crate stickers, or PE film with printed graphics, enhancing brand visibility and professionalism.
(II) Transportation
The transportation of the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable is managed to ensure timely delivery, product safety, and compliance with international and local transportation regulations. A comprehensive transportation plan is developed based on the order quantity, destination, and customer’s delivery timeline, with multiple transportation options available to meet different needs.
1. Transportation Modes
Road Transportation: For domestic shipments or short-distance deliveries (e.g., within a country or region), road transportation is the preferred option. It offers flexibility in terms of pickup and delivery times, and is suitable for both small and large orders. The cables are transported in closed 厢式货车 (box trucks) that are equipped with temperature control and moisture-proofing measures, ensuring the packaging remains dry and the cables are not exposed to extreme temperatures (e.g., above 60℃ or below -20℃). The trucks are operated by experienced drivers who are trained in handling cable products, with GPS tracking systems installed to allow real-time monitoring of the shipment’s location and status.
Rail Transportation: For medium-distance shipments (e.g., between cities or regions with well-developed rail networks), rail transportation is a cost-effective and reliable option. It is particularly suitable for large-volume orders, as railcars can carry multiple wooden crates or cardboard drums at once. The railcars used are enclosed to protect the cargo from weather conditions, and the shipment is secured with straps to prevent movement during transit. The transit time is pre-scheduled, allowing customers to plan their project timelines accurately.
Sea Transportation: For international shipments (e.g., to Europe, Asia, Africa, or the Americas), sea transportation is the primary mode. It is ideal for large-volume orders and offers lower transportation costs compared to air freight. The cables are loaded into shipping containers (20-foot or 40-foot containers) that are inspected for moisture and damage before loading. The containers are sealed with tamper-proof seals to ensure the cargo’s security during transit. For shipments to regions with high humidity (e.g., coastal areas), desiccant bags are placed inside the containers to absorb excess moisture, preventing the cable packaging from becoming damp. The sea freight process includes compliance with customs clearance procedures, with all necessary documents (e.g., commercial invoice, packing list, certificate of origin, and flame-retardant performance test report) prepared to avoid delays.
Air Freight: For urgent orders (e.g., customers with tight project deadlines) or small-volume shipments (e.g., sample deliveries), air freight is available. It offers the fastest delivery time, with most international shipments arriving within 3 - 7 days. The cables are packaged in lightweight cardboard drums or plastic containers to meet airline weight restrictions, and the packaging is labeled with “Air Freight Approved” stickers to comply with airline safety regulations. Air freight shipments are tracked closely, with real-time updates provided to the customer until the cargo is delivered.
2. Transportation Safety Measures
To ensure the cables remain undamaged during transportation, the following safety measures are implemented:
Cargo Securement: Regardless of the transportation mode, the cable packages are secured to prevent movement. In road trucks and railcars, the packages are strapped to the vehicle’s interior using elastic straps or wooden blocks. In shipping containers, the packages are arranged in a stable pattern, with voids filled with foam or cardboard to prevent shifting during sea waves or vehicle vibrations.
Environmental Protection: The cables are sensitive to extreme temperatures and moisture, so transportation vehicles are equipped with temperature and humidity monitoring devices. For shipments in hot weather, the vehicles are equipped with air conditioning or sunshades to prevent the cable packaging from overheating. For shipments in cold weather, heating elements or insulated covers are used to avoid the cable material becoming brittle due to low temperatures.
Handling Instructions: All packages are labeled with clear handling instructions, such as “Do Not Drop,” “Keep Upright,” and “Avoid Direct Sunlight.” Transportation personnel are trained to follow these instructions, and spot checks are conducted during loading and unloading to ensure compliance.
Insurance Coverage: All shipments are insured against loss, damage, or theft during transportation. The insurance coverage is arranged based on the cargo’s value, with the customer receiving a copy of the insurance certificate upon shipment. In the event of any transportation-related issues (e.g., accidents, delays, or damage), the customer is promptly notified, and a claims process is initiated to resolve the issue as quickly as possible.
3. Transportation Tracking and Notification
To keep customers informed about their shipment’s status, a real-time tracking system is provided:

Customers can contact the team via phone, email, or live chat to get updates on their shipment, resolve delivery issues, or request changes to the delivery address (if possible before the shipment reaches the destination).
(III) Shipment
The shipment process of the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable is streamlined to ensure efficiency, accuracy, and customer satisfaction. From order confirmation to final delivery, each step is managed with strict attention to detail, with clear communication between the sales team, production department, and logistics provider.
1. Order Processing and Shipment Preparation
Upon receiving a customer’s order, the sales team first confirms the order details, including the cable specifications (3X1.5mm²), quantity, packaging requirements, delivery address, and timeline. This information is then shared with the production department to schedule manufacturing—if the cable is in stock, the inventory team is notified to prepare the goods for shipment; if it is a custom order, the production department prioritizes the order based on the customer’s delivery timeline.
Once the cables are ready for shipment, the quality control team conducts a final inspection to ensure they meet the order requirements. The logistics team then prepares the necessary shipping documents, including:
Commercial Invoice: Details the product description, quantity, unit price, total amount, and payment terms.
2. Shipment Scheduling and Dispatch
The logistics team schedules the shipment based on the customer’s delivery timeline and the chosen transportation mode:

to ensure that the stranding quality of the cable core meets the requirements. Any cable core with uneven stranding, loose filling materials, or damaged insulation layers will be returned for rework to avoid affecting the subsequent sheath extrusion process.
4. Sheath Extrusion Process
The sheath extrusion process is the step of coating the sheathed layer on the surface of the cabled core, which is a critical link to ensure the cable's safety performance and durability. Similar to the insulation extrusion process, this step differs in material selection and process parameter control. The sheath layer uses flame-retardant polyvinyl chloride (PVC) material, which also undergoes drying treatment before extrusion to remove moisture from the material—this is essential to prevent bubbles from forming inside the sheath layer, which could compromise its structural integrity and flame-retardant effect.
During extrusion, the process parameters are adjusted according to the characteristics of the flame-retardant PVC material. The barrel temperature is controlled at approximately 165 - 195℃, and the die head temperature is set to 185 - 205℃. These temperature ranges are optimized to ensure the flame-retardant PVC material is fully melted and uniformly coated on the cable core surface, while avoiding material degradation due to overheating. The extrusion speed and traction speed are synchronized precisely to ensure the sheath layer has a uniform thickness (consistent with the 1.0 - 1.2mm specification) and a smooth surface, free from defects such as eccentricity, impurities, or surface cracks.
After extrusion, the sheathed cable immediately enters a cooling water tank for cooling and shaping. The cooling water temperature is maintained at 20 - 30℃, and the cooling time is controlled based on the cable diameter to ensure the sheath layer is fully solidified and adheres tightly to the cable core. Once cooled, the cable undergoes a series of inspections for the sheath layer, including thickness measurement, outer diameter verification, and flame-retardant performance testing. For flame-retardant performance testing, samples are taken from each production batch to conduct vertical burning tests in accordance with GB/T 19666 - 2019. Only cables that pass these tests—i.e., those that self-extinguish within 30 seconds after the fire source is removed and do not cause the spread of flame to the upper part of the sample—are allowed to proceed to the next process.
5. Finished Product Inspection and Pre-Packaging Process
Finished product inspection is the final quality control checkpoint in the cable production process, designed to ensure all outgoing products meet the required standards. This inspection covers multiple dimensions, including appearance, structural dimensions, electrical performance, mechanical performance, and flame-retardant performance.
Appearance Inspection: Inspectors visually check the cable's sheath layer for smoothness, ensuring there are no scratches, cracks, bubbles, or uneven coloration. Any cable with obvious surface defects is marked for rework or rejection.
Structural Dimension Inspection: Using precision measuring tools (such as a caliper and a laser diameter gauge), the cable's outer diameter, sheath thickness, core wire spacing, and overall length are measured. These dimensions must align with the product's design specifications—for example, the outer diameter must be within the 8 - 10mm range (excluding connectors), and the sheath thickness must not be less than 1.0mm.
Electrical Performance Inspection: This includes insulation resistance testing, voltage withstand testing, and DC resistance testing. The insulation resistance test uses a megohmmeter to measure the resistance between the conductor and the sheath layer at 20℃, requiring a minimum value of 100MΩ. The voltage withstand test applies a 1500V AC voltage between the conductor and the sheath for 1 minute, with no breakdown or flashover allowed. The DC resistance test measures the conductor's resistance per kilometer at 20℃, ensuring it does not exceed 12.1Ω/km.
Mechanical Performance Inspection: Tensile strength and elongation at break tests are conducted on the sheath and insulation layers. The tensile strength of the PVC material must be at least 12MPa, and the elongation at break must be no less than 150%, ensuring the cable can withstand moderate mechanical stress during installation and use without damage.
Only cables that pass all these inspections are transferred to the pre-packaging process. This process involves cutting, coiling, and labeling the cables. Based on customer orders, the cables are cut into specified lengths (e.g., 100 meters/roll or 200 meters/roll) using a high-precision cutting machine, ensuring clean, burr-free cuts. The cut cables are then coiled onto dedicated cable reels (made of high-strength cardboard or plastic) using an automatic coiling machine. The coiling tension is carefully controlled to ensure the cable is wound tightly and neatly, with no loose or overlapping sections. Finally, a product label is affixed to each cable reel, containing key information such as the product name, specification (3X1.5mm²), length, production date, batch number, execution standard (GB/T 19666 - 2019), and manufacturer’s name and contact information. This labeling ensures traceability and helps customers quickly identify and verify the product.
II. From the Perspective of General Product Information
(I) Packaging
The packaging of the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable is designed to prioritize product protection, transportation convenience, and storage safety. A multi-layer packaging structure is adopted to ensure the cable remains undamaged from the production workshop to the customer’s hands, even during long-distance transportation or prolonged storage.
1. Inner Packaging
The inner packaging directly protects the cable surface, preventing friction, dust contamination, or minor impact damage during transportation and storage. For coiled cables, the inner packaging uses high-strength polyethylene (PE) film, which is wrapped tightly around the cable reel. PE film offers excellent flexibility, wear resistance, and moisture resistance—its tight fit with the cable surface forms a barrier against dust, water vapor, and small debris, ensuring the cable remains clean and dry. Additionally, the PE film’s transparency allows customers to visually inspect the cable’s appearance without opening the packaging, facilitating quick quality checks upon receipt.
For bulk cable orders (e.g., large rolls of 1000 meters), the inner packaging may also include a layer of non-woven fabric between the PE film and the cable. The non-woven fabric adds an extra cushioning layer, reducing friction between the cable layers during unwinding and preventing surface scratches caused by direct contact with the PE film. This is particularly important for preserving the integrity of the flame-retardant sheath layer, as even minor scratches could compromise its flame-retardant performance.
2. Outer Packaging
The outer packaging is designed to withstand external pressure, impact, and environmental factors during transportation. Two main types of outer packaging are used, depending on the order quantity and transportation method:
Cardboard Drum Packaging: For standard orders (e.g., 100 - 500 meters per roll), the cable reels are placed inside cylindrical cardboard drums. These drums are made of multi-layer corrugated cardboard with a compressive strength of at least 1500N, ensuring they can withstand the weight of stacked packages during storage and transportation. The inner wall of the drum is lined with a waterproof PE film to prevent moisture intrusion in humid environments (e.g., sea freight or rainy weather). The drum lid is sealed with strong adhesive tape and reinforced with metal buckles to prevent accidental opening during transit. Each drum is labeled with the same product information as the inner cable reel, along with handling instructions (e.g., “Do Not Stack Over 3 Layers” or “Keep Dry”).
Wooden Crate Packaging: For large-volume orders (e.g., over 1000 meters) or shipments to regions with harsh transportation conditions (e.g., remote areas with rough roads), wooden crates are used. The crates are made of high-quality pine wood that has been treated for insect resistance and moisture proofing, complying with international shipping standards (e.g., ISPM 15 for wood packaging). The internal structure of the crate is customized to fit the cable reels, with foam padding placed between the reels and the crate walls to absorb shocks and prevent movement during transit. The crate is sealed with metal hinges and locks, and the exterior is marked with clear shipping labels, including the consignee’s address, contact information, and warning signs (e.g., “Fragile” or “Handle With Care”).
3. Special Packaging for Custom Orders
For customers with specific packaging requirements (e.g., small-length samples, color-coded packaging for different projects, or branding needs), custom packaging solutions are available:
Sample Packaging: Small-length samples (e.g., 1 - 5 meters) are packaged in transparent plastic tubes with labeled caps. The tubes protect the sample from damage and allow customers to inspect the cable’s flexibility and appearance. Each tube is accompanied by a product data sheet that summarizes the cable’s key specifications and performance parameters.
Color-Coded Packaging: For customers who need to distinguish cables for different projects or circuits, the outer packaging can be customized with color-coded labels or sleeves (e.g., red for power circuits, blue for lighting circuits). This helps streamline on-site installation and reduces the risk of wiring errors.
Branded Packaging: For business customers or distributors, the outer packaging can include the customer’s logo, brand name, or promotional messages. This is done through custom-printed cardboard drums, wooden crate stickers, or PE film with printed graphics, enhancing brand visibility and professionalism.
(II) Transportation
The transportation of the Flexible 3-Core Copper Cable 3X1.5mm² - OFC Flame-Retardant Power Cable is managed to ensure timely delivery, product safety, and compliance with international and local transportation regulations. A comprehensive transportation plan is developed based on the order quantity, destination, and customer’s delivery timeline, with multiple transportation options available to meet different needs.
1. Transportation Modes
Road Transportation: For domestic shipments or short-distance deliveries (e.g., within a country or region), road transportation is the preferred option. It offers flexibility in terms of pickup and delivery times, and is suitable for both small and large orders. The cables are transported in closed 厢式货车 (box trucks) that are equipped with temperature control and moisture-proofing measures, ensuring the packaging remains dry and the cables are not exposed to extreme temperatures (e.g., above 60℃ or below -20℃). The trucks are operated by experienced drivers who are trained in handling cable products, with GPS tracking systems installed to allow real-time monitoring of the shipment’s location and status.
Rail Transportation: For medium-distance shipments (e.g., between cities or regions with well-developed rail networks), rail transportation is a cost-effective and reliable option. It is particularly suitable for large-volume orders, as railcars can carry multiple wooden crates or cardboard drums at once. The railcars used are enclosed to protect the cargo from weather conditions, and the shipment is secured with straps to prevent movement during transit. The transit time is pre-scheduled, allowing customers to plan their project timelines accurately.
Sea Transportation: For international shipments (e.g., to Europe, Asia, Africa, or the Americas), sea transportation is the primary mode. It is ideal for large-volume orders and offers lower transportation costs compared to air freight. The cables are loaded into shipping containers (20-foot or 40-foot containers) that are inspected for moisture and damage before loading. The containers are sealed with tamper-proof seals to ensure the cargo’s security during transit. For shipments to regions with high humidity (e.g., coastal areas), desiccant bags are placed inside the containers to absorb excess moisture, preventing the cable packaging from becoming damp. The sea freight process includes compliance with customs clearance procedures, with all necessary documents (e.g., commercial invoice, packing list, certificate of origin, and flame-retardant performance test report) prepared to avoid delays.
Air Freight: For urgent orders (e.g., customers with tight project deadlines) or small-volume shipments (e.g., sample deliveries), air freight is available. It offers the fastest delivery time, with most international shipments arriving within 3 - 7 days. The cables are packaged in lightweight cardboard drums or plastic containers to meet airline weight restrictions, and the packaging is labeled with “Air Freight Approved” stickers to comply with airline safety regulations. Air freight shipments are tracked closely, with real-time updates provided to the customer until the cargo is delivered.
2. Transportation Safety Measures
To ensure the cables remain undamaged during transportation, the following safety measures are implemented:
Cargo Securement: Regardless of the transportation mode, the cable packages are secured to prevent movement. In road trucks and railcars, the packages are strapped to the vehicle’s interior using elastic straps or wooden blocks. In shipping containers, the packages are arranged in a stable pattern, with voids filled with foam or cardboard to prevent shifting during sea waves or vehicle vibrations.
Environmental Protection: The cables are sensitive to extreme temperatures and moisture, so transportation vehicles are equipped with temperature and humidity monitoring devices. For shipments in hot weather, the vehicles are equipped with air conditioning or sunshades to prevent the cable packaging from overheating. For shipments in cold weather, heating elements or insulated covers are used to avoid the cable material becoming brittle due to low temperatures.
Handling Instructions: All packages are labeled with clear handling instructions, such as “Do Not Drop,” “Keep Upright,” and “Avoid Direct Sunlight.” Transportation personnel are trained to follow these instructions, and spot checks are conducted during loading and unloading to ensure compliance.
Insurance Coverage: All shipments are insured against loss, damage, or theft during transportation. The insurance coverage is arranged based on the cargo’s value, with the customer receiving a copy of the insurance certificate upon shipment. In the event of any transportation-related issues (e.g., accidents, delays, or damage), the customer is promptly notified, and a claims process is initiated to resolve the issue as quickly as possible.
3. Transportation Tracking and Notification
To keep customers informed about their shipment’s status, a real-time tracking system is provided:
