Detailed Introduction to H07V-U 1.5mm² Single-Core Solid Copper PVC Insulated Wire (450/750V)
I. From the Perspective of the Product Itself
(1) Specification Parameters
The specification parameters of H07V-U 1.5mm² single-core solid
Copper PVC Insulated Wire are precisely set to adapt to the needs of various electrical environments.
The rated voltage is clearly 450/750V, which means that the wire can withstand an AC voltage of 450V during normal operation, and can tolerate a voltage impact of 750V in case of short-term overvoltage. This characteristic enables it to meet the requirements of electrical systems in most civil and small industrial places, providing reliable voltage support for circuit operation.
The wire diameter specification is 1.5mm², and the corresponding conductor diameter is approximately 1.38mm. The conductor of this size is carefully designed to ensure conductivity while taking into account the overall
Flexibility and installation convenience of the wire. The thickness of the insulation layer is about 0.7mm, made of high-quality PVC material, so that the overall outer diameter of the wire is about 2.78mm, which can not only provide good insulation protection, but also not increase the difficulty of threading due to excessive outer diameter.
Current-carrying capacity is one of the important indicators to measure the performance of wires. The current-carrying capacity of the wire is about 19A when laid in air; when laid in a pipe (three wires), the current-carrying capacity is about 14A. Such current-carrying capacity is sufficient to support the normal operation of various medium and low-power electrical equipment, such as common lighting fixtures and small household appliances.
The DC resistance of the conductor is also strictly controlled. At 20℃, its maximum DC resistance does not exceed 12.1Ω/km. The low DC resistance ensures that the loss of current during transmission is small, improves the efficiency of power transmission, and also reduces the heat generated due to excessive resistance, reducing potential safety hazards.
The operating temperature range is -15℃ to 70℃. Within this range, all physical and chemical properties of the wire can remain stable. Even in cold winters or hot summers, or when equipment operation generates a certain amount of heat, the wire will not have problems such as aging and cracking of the insulation layer and degradation of conductor performance, ensuring the continuous and stable operation of the circuit.
(2) Characteristic Uses
H07V-U 1.5mm² single-core solid
Copper PVC Insulated Wire has unique application value in many fields due to its excellent performance.
In the field of home decoration, it is an ideal choice for lighting circuits. Whether it is the ceiling lamp in the bedroom, the chandelier in the living room, or the wall lamp in the corridor, they can be connected through this wire to ensure stable lighting. Its stable current-carrying capacity can meet the needs of lighting fixtures with different powers, and the single-core solid structure and good flexibility make it more convenient in the process of wall embedding and ceiling wiring, and can easily cope with various complex wiring environments.
For small household appliances in the home, this wire can also provide reliable power support. Devices such as TVs, set-top boxes, routers, desk lamps, and electric fans have relatively low power. The 1.5mm² wire diameter and corresponding current-carrying capacity can fully meet their power needs.

(3) Material and Style
Conductor Material: High-purity electrolytic copper is used, with a purity of more than 99.95%. High-purity copper has excellent conductivity, which can transmit current quickly and efficiently, reducing energy loss. At the same time, copper has good ductility and toughness, which can be drawn into uniform solid conductors during processing, and is not easy to break during installation and use, ensuring the service life and reliability of the wire. In addition, copper has good oxidation resistance, and the surface of the conductor is not easy to oxidize and rust during long-term use, ensuring the stability of conductivity.
Insulation layer material: High-quality PVC (polyvinyl chloride) material is selected. PVC material has excellent insulation performance, which can effectively isolate the conductor from the outside world, prevent electric leakage accidents, and provide a solid guarantee for electrical safety. It also has good wear resistance, and is not easy to be damaged when rubbing against wire pipes, walls, etc. during wiring, protecting the internal conductor. At the same time, PVC material has a certain resistance to general acid and alkali substances, can adapt to different environmental conditions, and extend the service life of the wire. In addition, PVC material has good plasticity, and can be uniformly coated on the surface of the conductor during production to form a smooth and flat insulation layer.
Style design: The wire has a single-core solid structure, which makes the wire have good mechanical strength, not easy to deform during fixed wiring, and can maintain the stability of the shape. The appearance is cylindrical, with a smooth and flat surface, no burrs, bubbles, depressions and other defects. It is not only beautiful, but also can reduce frictional resistance during threading, facilitating construction.
In terms of color, the wire provides a variety of options, commonly including red, blue, black, yellow, green, etc. Different colors can be used to distinguish different circuit functions. For example, red is usually used as the live wire, blue as the neutral wire, and yellow-green as the
Ground Wire. This design is convenient for construction personnel to identify and distinguish during installation, reducing the probability of wiring errors and improving construction quality and efficiency.
(4) Production Process
The production process of H07V-U 1.5mm² single-core solid copper PVC insulated wire strictly follows high-standard process requirements to ensure that every meter of wire has reliable quality.
Conductor manufacturing: First, high-purity electrolytic copper is selected as the raw material, which is smelted to remove impurities to obtain copper water with meet the required purity. The copper water is cooled to form copper rods through continuous casting process. The quality of the copper rod directly affects the performance of the subsequent conductor. Therefore, during the casting process, parameters such as temperature and cooling speed need to be strictly controlled to ensure that the copper rod has a uniform texture, no bubbles and cracks.
Next, the copper rod enters the wire drawing process. Through a wire drawing machine and a series of dies of different specifications, the copper rod is gradually drawn into a solid
Copper Wire with a diameter of 1.38mm. During the wire drawing process, the wire drawing speed and the size of the die must be accurately controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth. At the same time, a certain amount of heat will be generated during the wire drawing process, so the copper wire needs to be cooled to prevent its performance from being affected by excessive temperature. After wire drawing, the copper wire also needs to be annealed. By heating and heat preservation, the internal stress of the copper wire is eliminated, and its flexibility and ductility are improved, which is convenient for the subsequent insulation layer coating process.
Insulation layer extrusion: Coating the insulation layer on the surface of the conductor is a key process to ensure the insulation performance of the wire. The qualified Solid Copper Wire is sent to the extruder, and high-quality PVC 颗粒 raw materials are added to the hopper of the extruder at the same time. The PVC particles are heated and melted in the extruder to become a molten fluid.
The die of the extruder is accurately designed according to the specifications of the wire. The molten PVC fluid is uniformly coated on the surface of the copper wire through the die to form an insulation layer with a thickness of about 0.7mm. During the extrusion process, it is necessary to strictly control the extrusion temperature (usually between 160℃-180℃), extrusion speed and pressure to ensure that the insulation layer has uniform thickness, is closely combined with the copper wire, and has no defects such as bubbles, pinholes, and eccentricity. If the temperature is too high, the PVC material may decompose, affecting the insulation performance; if the temperature is too low, the PVC material has poor fluidity, making it difficult to form a uniform insulation layer.
Cooling and solidification: The extruded wire immediately enters the cooling water tank for cooling. The water temperature in the cooling water tank is generally controlled at 20℃-30℃. Through the action of cold water, the PVC Insulation layer coated on the surface of the copper wire is quickly cooled and solidified to form a stable structure. The cooling time needs to be adjusted according to the specifications of the wire and the extrusion speed to ensure that the insulation layer is completely solidified and the hardness and toughness meet the specified requirements. During the cooling process, it is necessary to avoid large fluctuations in water temperature to prevent internal stress in the insulation layer, which may affect the performance of the wire.
Quality inspection: The cooled wire needs to undergo a series of strict quality inspections. Appearance inspection is the first step. Workers check whether the surface of the wire is smooth and flat, whether the insulation layer has defects such as bubbles, cracks, and scratches, and whether the color is uniform through the naked eye or special equipment.
Dimension inspection is to accurately measure parameters such as the conductor diameter, insulation layer thickness, and overall outer diameter of the wire through special measuring tools to ensure that they meet the design requirements. Electrical performance testing includes insulation resistance testing and withstand voltage testing. Insulation resistance testing is used to test the insulation performance of the insulation layer. Withstand voltage testing is to apply a certain high voltage to both ends of the wire to observe whether there is a breakdown phenomenon to verify its insulation strength.
In addition, sampling tests will be conducted on the mechanical properties of the wire, such as tensile strength and elongation at break, to ensure that the wire has sufficient mechanical strength during installation and use. Only wires that pass all testing items can enter the next process.
Take-up and packaging: The wires that pass the quality inspection are sent to the take-up machine for winding. The take-up machine winds the wire neatly on the reel according to the set length (usually 100 meters, 200 meters, 500 meters, etc.). During the take-up process, the tension must be controlled to avoid excessive stretching or loosening of the wire, ensuring that the winding is tight and neat.
After winding, the wire is packaged. Usually, the wire on the reel is tightly wrapped with plastic film to prevent dust, moisture, etc. from entering. At the same time, the name, specification, length, production date, batch number, execution standard and other information of the product are marked on the reel for easy identification and traceability.
II. From the Perspective of General Product Information
(1) Packaging
The packaging design of H07V-U 1.5mm² single-core solid copper PVC insulated wire fully considers the product's protection, transportation and storage needs to ensure that the product remains in good condition before reaching the customer.
For wires of conventional lengths such as 100 meters and 200 meters, plastic reel packaging is adopted. The plastic reel is made of high-strength polyethylene material, which has good compression and impact resistance, and can protect the wire from external extrusion and collision during transportation and storage. The diameter and width of the reel are designed according to the length and diameter of the wire to ensure that the wire can be neatly wound on it without loosening or knotting.
Both ends of the reel are provided with circular baffles. The diameter of the baffle is larger than the maximum diameter of the wound wire, which can effectively prevent the wire from slipping off the reel during handling and storage. The baffle is printed with clear product identification, including product name, specification (1.5mm², 450/750V), length, production date, batch number, manufacturer information, etc., which is convenient for customers to quickly identify product information.
For wires of longer lengths such as 500 meters, wooden reel packaging is adopted. The wooden reel is made of high-quality pine or fir, which has been dried and has high strength and stability, and can bear large weight and pressure. After the wire is wound on the wooden reel, it is tightly wrapped with a strong plastic film or woven cloth to form a sealed whole, which plays the role of moisture-proof, dust-proof and wear-proof. The center of the wooden reel is provided with a metal shaft hole, which is convenient for handling and loading/unloading with forklifts, cranes and other equipment, improving transportation efficiency.
Whether it is plastic reel or wooden reel packaging, eye-catching warning signs such as "Handle with Care", "Moisture and Sun Protection", "Keep Away from Fire" are pasted on the outside of the package to remind operators to pay attention to relevant matters during handling and storage, and avoid product damage due to improper operation.
In addition, for small batches of samples or retail products, small-sized plastic packaging or carton packaging is also used, which is convenient for customers to carry and use. The necessary product information and warning signs are also marked on the packaging.
(2) Transportation

The choice of transportation mode depends on the shipment volume, transportation distance and customer needs. For domestic short-distance transportation (usually within 500 kilometers), road transportation is preferred. Road transportation has high flexibility and can realize door-to-door service, which is suitable for small-batch and multi-batch cargo transportation. The transport vehicle is a closed truck, and the interior of the carriage must be kept clean and dry, without oil stains, sharp debris, etc., to prevent the wire packaging from being contaminated or scratched. When loading goods, the wire reels should be arranged neatly, and firmly fixed in the carriage with ropes or special fixing devices to avoid reel rolling and collision caused by bumps, turns, brakes, etc. during vehicle operation, resulting in wire damage.
For long-distance transportation or large-volume orders, railway transportation can be chosen. Railway transportation has the characteristics of large transportation volume, good stability and relatively low cost, and is suitable for long-distance and large-scale cargo transportation. During railway transportation, the wire reels need to be loaded and fixed in accordance with the requirements of railway transportation, and containers or boxcars are usually used for transportation to prevent the goods from being affected by natural environments such as rain and sun.
For export orders, sea or air transportation is selected according to the destination and customer requirements. Sea transportation is suitable for large quantities of goods, with low cost but long transportation time. During sea transportation, the wire reels need to undergo strict moisture-proof and anti-salt spray treatment. Usually, waterproof cloth and anti-rust paper are added to the outside of the packaging to ensure that the products are not damp or corroded during long-term sea transportation. Air transportation is suitable for small batches and urgent orders, with fast transportation speed but high cost. When transporting by air, it is necessary to comply with the regulations of the airline to ensure that the packaging meets the requirements of air transportation and the weight and volume are within the limits.
Throughout the transportation process, the goods should be tracked and monitored in real time. Through the logistics information system, the position and transportation status of the goods are grasped in real time, and problems arising during transportation are found and handled in a timely manner.
