H05V-U H07V-U 300/500V 450/750V Electrical Cable 1.5mm 2.5mm Solid Single Core Copper Wire PVC Insulated for House Building Wiring (White, Black, Red)

The specification parameters of H05V-U and H07V-U series Electrical Cables are crucial for their adaptation to different residential and building wiring scenarios. Each parameter has undergone precise design and rigorous testing to ensure the safety and stability of power transmission.

In terms of conductor specifications, both types of cables are available in two cross-sectional sizes: 1.5mm² and 2.5mm². The 1.5mm² conductor has a diameter of 1.38mm, and the 2.5mm² conductor has a diameter of 1.78mm. Both are solid high-purity copper wires. This solid structure ensures the rigidity and stability of the conductor, facilitating the maintenance of straightness during pipe 穿 laying.

In terms of rated voltage, the H05V-U cable has a rated voltage of 300/500V, where 300V is the rated operating voltage of the cable and 500V is its rated insulation voltage, suitable for scenarios with relatively low voltage requirements. The H07V-U cable has a rated voltage of 450/750V, with 450V as the rated operating voltage and 750V as the rated insulation voltage, which can adapt to higher voltage environments and has stronger ability to withstand voltage fluctuations.

Continuous current-carrying capacity is an important indicator to measure the current-carrying capacity of the cable, and it is affected by the ambient temperature. At an ambient temperature of 30°C, the continuous current-carrying capacity of the 1.5mm² H05V-U cable is 16A, and that of the 2.5mm² specification is 25A. When the ambient temperature rises to 40°C, the current-carrying capacity of the 1.5mm² specification drops to 13A, and that of the 2.5mm² specification drops to 21A. For the H07V-U cable at 30°C, the continuous current-carrying capacity of the 1.5mm² specification is 18A, and that of the 2.5mm² specification is 28A. When the ambient temperature reaches 40°C, the current-carrying capacity of the 1.5mm² specification is 15A, and that of the 2.5mm² specification is 24A. This requires that in practical applications, the cable specification should be reasonably selected according to the ambient temperature and the power of electrical equipment to avoid safety issues caused by overload.

The thickness of the insulation layer is also clearly specified. The PVC Insulation layer thickness of both H05V-U and H07V-U cables with 1.5mm² specification is 0.7mm, and that of the 2.5mm² specification is 0.8mm. A suitable insulation layer thickness can ensure that the cable has good insulation performance, effectively isolate current, and prevent electric leakage accidents.

Insulation resistance is an important parameter reflecting insulation performance. The insulation resistance of both cables at room temperature is ≥100MΩ, which ensures that the cable can maintain a good insulation state during long-term use. At the same time, they can both withstand 2000V AC voltage for 1 minute without breakdown, further verifying the reliability of the insulation layer.

In addition, the outer diameter of the cable varies depending on the specification. The outer diameter of 1.5mm² H05V-U and H07V-U cables is approximately 3.5mm, and that of 2.5mm² is approximately 4.2mm. This size design enables it to easily pass through wall pipes and trunking, facilitating construction and installation. The minimum bending radius is 4 times the outer diameter of the cable. The minimum bending radius of 1.5mm² cable is 14mm, and that of 2.5mm² is 16.8mm. The small bending radius allows the cable to flexibly turn during wiring, adapting to complex wiring environments.

H05V-U and H07V-U series electrical cables have clear and diverse characteristic applications in residential and building wiring by virtue of their respective performance characteristics, which can meet the electricity needs of different scenarios.

Due to its rated voltage of 300/500V and relatively moderate current-carrying capacity, H05V-U cable is suitable for low-load and medium-load electricity scenarios. In residential bedrooms, 1.5mm² H05V-U cable is often used in lighting circuits to connect lighting equipment such as ceiling lamps and wall lamps. These devices have low power, and the 16A current-carrying capacity can fully meet the demand. At the same time, it can also be used to connect small household appliances in the bedroom, such as desk lamps, laptop chargers, routers, etc., to provide stable power support for these devices. The 2.5mm² H05V-U cable is suitable for socket circuits in bedrooms, which can meet the electricity needs of medium-power appliances such as hair dryers and electric irons, and can also provide power for wall-mounted air conditioners (1.5 horsepower and below). Its 25A current-carrying capacity can ensure the stable operation of the air conditioner.

In the living room area, 1.5mm² H05V-U cable can be used for wiring of lighting equipment such as chandeliers and downlights, and 2.5mm² cable can be connected to ordinary sockets in the living room to supply power to devices such as televisions, set-top boxes, and water dispensers. In addition, in the study room, 1.5mm² cable can be used for the power supply lines of desk lamps and computer hosts, and 2.5mm² cable can meet the electricity needs of devices such as printers.

H07V-U cable has a higher rated voltage and larger current-carrying capacity, which is suitable for scenarios with high electricity load and high requirements for power stability. In the kitchen, various electrical appliances have high power. 2.5mm² H07V-U cable is often used in the socket circuit of the kitchen to supply power to high-power devices such as microwave ovens, induction cookers, and electric ovens. The 28A current-carrying capacity can easily cope with the current demand when these devices work simultaneously. 1.5mm² H07V-U cable can be used for lighting lines in the kitchen and power supply for small kitchen appliances such as coffee machines and toasters.

The bathroom is a relatively special area in the home. Although there is a certain degree of humidity, H07V-U cable can still be used with reasonable wiring. 2.5mm² cable can be used for the special line power supply of bathroom electric water heaters (with power below 3000W) to ensure its safe and stable operation; 1.5mm² cable can be used for the power supply lines of bathroom lighting and exhaust fans.

In terms of connecting small power equipment, H07V-U cable also performs well. 2.5mm² cable can be used as a special line for equipment such as washing machines and dryers. These devices have high power and long running time, requiring stable power supply; 1.5mm² cable can be used for socket circuits connecting equipment such as vacuum cleaners and floor-sweeping robots.

In public areas of buildings, such as corridors and elevator rooms, H05V-U cable can be used for lighting lines, and H07V-U cable can be used for power supply of public sockets, such as corridor emergency sockets and elevator room maintenance sockets, to meet the electricity needs of public areas.

In terms of material selection and style design, H05V-U and H07V-U series electrical cables fully consider the actual needs of residential and building wiring, taking into account performance, safety and practicality.

The Conductor Material is high-purity electrolytic copper with a purity of ≥99.9%. This high-purity copper has excellent conductivity with a conductivity of ≥58MS/m, which can effectively reduce energy loss during current transmission and improve power utilization efficiency. The solid structure design makes the conductor have moderate rigidity, which is not easy to bend and deform during pipe 穿 laying, can maintain good straightness, and reduce current loss and line faults caused by bending. At the same time, the Solid Copper Wire has high mechanical strength and can withstand a certain amount of tension and pressure, and is not easy to be damaged during construction and use.

The insulation layer is made of rigid polyvinyl chloride (PVC) material with a temperature resistance of 60-70°C, which has many excellent characteristics. Firstly, it has good insulation performance with an insulation resistance of ≥100MΩ, which can effectively isolate current, prevent electric leakage accidents, and ensure electricity safety. Secondly, the PVC insulation layer has good wear resistance, which can resist friction from the inner wall of the pipe during pipe 穿 laying, reducing damage to the insulation layer; at the same time, it can also resist erosion from environmental factors such as wall cement and dust, extending the service life of the cable. In addition, the insulation layer has a flame retardant rating of UL94 V-0, which can self-extinguish quickly in case of fire, will not produce a large amount of toxic smoke, can effectively delay the spread of fire, and gain time for personnel evacuation and fire rescue.

In terms of style, both cables are single-Core Cables. This design simplifies the wiring process and is convenient for installation and maintenance in narrow spaces. The appearance of the cable is round with a moderate outer diameter, 1.5mm² is approximately 3.5mm, and 2.5mm² is approximately 4.2mm. This size enables it to easily pass through various specifications of wall pipes and trunking, reducing construction difficulty.

In terms of color, three colors are available: white, black and red, and the color design strictly follows international wiring specifications. White is often used for neutral wires, and black and red are used as phase wires. This intuitive color distinction can help construction personnel quickly identify the function of the cable, reduce the risk of wiring errors, and improve construction efficiency and wiring accuracy. At the same time, the unified color standard also facilitates later line maintenance and repair. Maintenance personnel can quickly judge the nature of the line according to the color, shortening the troubleshooting time.

The production process of H05V-U and H07V-U series electrical cables is rigorous and meticulous. Every link from raw materials to finished products is strictly controlled to ensure that product quality meets relevant standards and usage requirements.

Conductor manufacturing is the first step in the production process. High-purity electrolytic copper ingots are selected as raw materials, and impurities are removed through high-temperature smelting to obtain copper water with higher purity. The copper water is made into copper rods through continuous casting process, and the diameter of the copper rods is precisely controlled according to the specifications of the cable. The copper rod diameter corresponding to 1.5mm² cable is smaller, and that corresponding to 2.5mm² cable is larger. Subsequently, the copper rod enters the wire drawing process, and the copper rod is drawn into a solid copper wire with the required diameter by a wire drawing machine. During the wire drawing process, it is necessary to accurately control the wire drawing speed and the size of the die to ensure that the diameter of the copper wire is uniform and the surface is smooth and flawless. After wire drawing, the copper wire is annealed, heated to a certain temperature and then slowly cooled to eliminate internal stress in the copper wire, improve its mechanical properties and conductivity, and make the copper wire have better Flexibility and conductivity.

Extrusion of the insulation layer is a key link in the production process. The treated solid copper wire is used as a conductor and fed into the extruder, and a layer of PVC insulation is extruded outside the conductor. Before extrusion, PVC raw materials need to undergo strict screening and drying treatment to remove impurities and moisture to ensure the quality of the insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed. Generally, the extrusion temperature is set at 160-180°C, which can fully melt the PVC material and evenly coat it on the surface of the conductor to form an insulation layer with uniform thickness. The thickness of the insulation layer should be strictly controlled according to the design requirements. The insulation layer thickness of 1.5mm² cable is 0.7mm, and that of 2.5mm² cable is 0.8mm to ensure that the insulation performance meets the standard. The extruded cable is quickly cooled through a cooling water tank to shape the insulation layer and ensure the dimensional stability of the cable.

The cooled cable enters the printing process, and the product model (such as H05V-U, H07V-U), specification (1.5mm², 2.5mm²), rated voltage, production batch number, execution standard and other information are printed on the surface of the insulation layer by a printing machine. Special ink is used for printing, which is required to be clear, firm and not easy to fall off, so as to facilitate product identification and traceability.

After printing, the cable undergoes a spark test, which is an important step to detect whether the insulation layer has defects. The cable passes through a high-voltage electrode. If the insulation layer has defects such as pinholes and damage, spark discharge will occur, and the equipment will immediately alarm and mark it for subsequent processing. Only cables that pass the spark test can enter the next process.

Next, the cable is cut according to the specified length. Usually, the length of each coil of cable is 100 meters, 200 meters or 300 meters, and the specific length can be adjusted according to customer needs. The cut cable is wound on a cable reel or spool. During the winding process, it is necessary to ensure that the cable is arranged neatly to avoid twisting and 缠绕，so as to facilitate transportation and laying.

Finally, the finished cable undergoes a comprehensive quality inspection, including testing of conductor diameter, insulation layer thickness, insulation resistance, voltage resistance performance, current-carrying capacity and other indicators, to ensure that the product quality meets international standards such as EN 50525. Qualified cables are packaged with moisture-proof and dust-proof plastic film or woven bags to protect the cables from damage during transportation and storage. Relevant product information is marked on the package for customers' identification and acceptance.

The entire production process uses a production line with a high degree of automation, which reduces errors caused by manual operations and improves production efficiency and product quality stability. At the same time, the production workshop is equipped with advanced testing equipment and monitoring systems to monitor the production process in real time, timely detect and solve problems in production, and ensure that each batch of products can meet quality requirements.

The packaging design of H05V-U and H07V-U series electrical cables fully considers product protection, transportation, storage and customer convenience, and strives to ensure product quality in all links.

Different packaging methods are adopted for cables of different lengths. Common packaging forms include cable reel packaging and spool packaging. For cables with lengths of 100 meters, 200 meters and 300 meters, cable reel packaging is usually adopted. The cable reel is made of high-strength wood or plastic materials, which has good pressure resistance and wear resistance, and can effectively protect the cable from external impact and extrusion during transportation and storage. The diameter of the cable reel depends on the length and specification of the cable, generally between 300-600mm, to ensure that the cable can be neatly wound on it, avoiding looseness, distortion or mutual friction. After the cable is wound, a layer of moisture-proof film is covered on its surface to prevent the cable from getting damp and affecting the insulation performance. Both sides of the cable reel are provided with baffles, on which clear product information is printed, including product model, specification, length, rated voltage, production batch number, execution standard, manufacturer name and contact information, etc., to facilitate customers' quick identification and acceptance.

For short-length cables, such as 10 meters, 20 meters, 50 meters, etc., spool packaging is mostly used. The spool is made of plastic, which is light and durable. The cable is neatly wound on the spool and covered with a transparent plastic packaging bag, which can not only protect the cable from dust and impurities, but also allow customers to intuitively see the appearance and color of the cable. The basic information of the product is also printed on the packaging bag for customers' access and management.

In addition, in order to meet the special needs of customers, customized packaging services can also be provided. For example, cutting and packaging according to the length required by customers, or using packaging materials and logos specified by customers.

During the packaging process, packaging specifications are strictly followed to ensure that the cable is in a stable state in the package and will not be displaced or damaged due to bumps during transportation. For export products, the packaging must also meet the relevant standards and requirements of international transportation, such as using fumigated wooden cable reels to prevent the spread of diseases and pests; marking clear English logos and internationally accepted transportation marks on the packaging, such as moisture-proof, upward, stacking limit, etc., to ensure that the products are safe and intact during international transportation.

The transportation process of H05V-U and H07V-U series electrical cables strictly abides by relevant transportation regulations and requirements to ensure the safety and integrity of products during transportation.

In domestic transportation, road transportation, railway transportation and other methods can be selected according to the transportation distance, quantity of goods and customer needs. Road transportation has the characteristics of high flexibility and fast delivery speed, and is suitable for short-distance and small-batch transportation. The transport vehicles are closed vans, which can effectively prevent the cables from being exposed to direct sunlight, rain, dust and other external factors. During loading, the cable reels or spools must be arranged neatly and fixed firmly with ropes or steel belts to prevent displacement, collision or falling due to vehicle bumps during transportation. For heavier cable reels, forklifts are used for loading and unloading to ensure operational safety.

Railway transportation is suitable for long-distance and large-batch transportation, with the advantages of large transportation capacity, low cost and good stability. The cables are loaded into containers or boxcars of railway freight cars, which can provide good protection for the cables. During loading, attention must also be paid to the fixing and arrangement of the cables to avoid mutual extrusion and collision. During transportation, close attention is paid to the transportation status of the goods, and the position and arrival time of the goods are tracked in a timely manner through the railway freight tracking system.

During transportation, it is necessary to avoid the cables being affected by extreme temperatures, humidity and mechanical impact. The PVC insulation layer may soften in high-temperature environments, affecting the insulation performance; in low-temperature environments, it may become brittle and easy to crack. Therefore, during transportation, efforts should be made to avoid high-temperature and low-temperature periods, or take corresponding heat preservation and cooling measures. At the same time, prevent the cables from being scratched by sharp objects or being subjected to heavy pressure, so as not to damage the insulation layer and conductors.

For export products, sea freight and air freight are mainly used. Sea freight is suitable for long-distance transportation of large quantities of products, with relatively low cost but long transportation time. During sea transportation, the cable reels must be firmly fixed and moisture-proof treated to prevent seawater erosion and dampness. Air freight is suitable for emergency orders or small-batch product transportation, which can quickly deliver the products to the destination, but the cost is relatively high. When transporting by air, it is necessary to comply with the relevant regulations of the airline to ensure that the packaging and weight of the goods meet the requirements.
