At the same time, electrolytic copper is soft, which is convenient for stranding and other processing techniques, ensuring the quality and performance of the conductor.

Insulation Layer Material: The insulation layer is made of polyvinyl chloride (PVC) material, which has good insulation performance, corrosion resistance, and weather resistance. PVC material is non-conductive, which can effectively block current and prevent electric leakage. In addition, it can resist the erosion of some chemical substances and adapt to different environmental conditions. At the same time, PVC material has certain flexibility, so that the wire is not easy to damage the insulation layer during bending and installation.

Style Design: The overall style is a round wire with a smooth and flat surface. This design is not only convenient for the storage and laying of the wire but also can reduce friction with other objects during wiring, protecting the insulation layer. The multi-strand stranded conductor structure makes the wire look more exquisite and also improves its use performance.

Copper Wire Drawing: First, high-purity electrolytic copper ingots are made into copper rods through heating, rolling, and other processes, and then the copper rods are drawn into fine copper wires of the required diameter through a wire drawing machine. During the drawing process, it is necessary to strictly control the drawing speed and tension to ensure that the diameter of the copper wire is uniform, the surface is smooth, and defects such as cracks are avoided.

Stranding Process: A number of drawn copper wires are stranded according to a certain stranding direction and pitch to form a conductor. During the stranding process, it is necessary to ensure that each copper wire is evenly stressed and tightly stranded to improve the mechanical strength and electrical conductivity of the conductor. The size of the stranding pitch will affect the flexibility and tensile resistance of the conductor, which needs to be accurately controlled according to the specifications and requirements of the product.

Insulation Layer Extrusion: An extruder is used to evenly coat the polyvinyl chloride material on the surface of the stranded conductor to form an insulation layer. During the extrusion process, it is necessary to control the extrusion temperature, speed, and pressure to ensure that the thickness of the insulation layer is uniform, the surface is smooth, and it is closely combined with the conductor. At the same time, the corresponding color masterbatch should be added to the insulation layer to ensure that the wire color meets the requirements and is uniform.

Cooling and Solidification: The wire with the extruded insulation layer needs to be cooled through a cooling water tank to make the polyvinyl chloride material solidify quickly and shape the shape and performance of the insulation layer. During the cooling process, it is necessary to control the water temperature and cooling time to ensure the stable quality of the insulation layer.

Quality Inspection: Strict quality inspection is carried out in all links of the production process. Including the detection of the diameter and purity of copper wires, the detection of the stranding quality of conductors, the detection of the thickness, insulation resistance, and voltage resistance performance of the insulation layer, etc. The finished wire also needs to undergo overall performance tests, such as conductor resistance test, aging test, low-temperature bending test, etc., to ensure that each batch of products meets the IEC 60227 standard and related quality requirements.

Packaging Method: For the convenience of transportation and storage, the copper stranded wire is packaged in rolls. The length of each roll of wire is usually 100 meters, and different lengths such as 50 meters and 200 meters can also be customized according to the special requirements of customers. When rolling, the wire is neatly wound on a paper or plastic reel. The size of the reel is designed according to the length and diameter of the wire to ensure that the wire will not be excessively squeezed or stretched during winding.

Packaging Materials: The reel is made of high-strength paper or plastic materials, which have certain compression resistance and moisture resistance. Paper reels have low cost, are easy to recycle, and are more environmentally friendly; plastic reels have better corrosion resistance and durability, suitable for use in humid or harsh environments.
