This clear color identification also facilitates electrical personnel to inspect and manage the system.

• Copper Wire Drawing: First, high-purity electrolytic copper ingots are made into copper rods through smelting, casting and other processes, and then the copper rods are drawn into ultra-fine copper wires of the required diameter through a wire drawing machine. During the wire drawing process, it is necessary to strictly control the drawing speed, temperature and lubrication conditions to ensure that the diameter of the copper wire is uniform, the surface is smooth, and avoid cracks, scratches and other defects. The drawn copper wire also needs to be annealed to eliminate internal stress and improve the flexibility and conductivity of the copper wire, preparing for the subsequent stranding process.

• Conductor Stranding: According to the requirements of different specifications, a certain number of ultra-fine copper wires are stranded on special stranding equipment. During the stranding process, it is necessary to accurately control the stranding pitch and tension to ensure that each strand of copper wire is evenly stressed and tightly stranded. A reasonable stranding pitch can not only enhance the flexibility of the conductor, but also improve the mechanical strength and fatigue resistance of the conductor, making the cable not easy to be damaged in the environment of frequent bending and vibration.

• Insulation Extrusion: After heating and melting the PVC material, it is evenly coated on the surface of the Stranded Conductor through an extruder to form an insulation layer. During the extrusion process, it is necessary to strictly control the extrusion temperature, pressure and speed to ensure that the insulation layer has a uniform thickness, a smooth surface, and is closely combined with the conductor. For H05V-K and H07V-K models, different formulations of PVC materials need to be used, and the corresponding extrusion parameters should be adjusted to meet their different temperature resistance requirements.

• Cooling and Solidification: The cable with the extruded insulation layer enters the cooling water tank for cooling and solidification, so that the PVC material is quickly shaped, ensuring the dimensional stability and performance of the insulation layer. During the cooling process, the water temperature should be controlled to avoid cracks or internal stress in the insulation layer due to too fast cooling speed.

• Printing Identification: On the surface of the cooled cable, product information such as specification model, rated voltage, executive standard, production batch number, production date, etc. is printed by a printing machine. The printing should be clear and firm, facilitating product identification, traceability and quality control.
