First, high-purity electrolytic copper ingots are smelted and cast into copper rods. The quality of the copper rods is strictly controlled to ensure their purity and uniformity. Then, the copper rods are drawn into copper wires of the required diameter through a wire drawing machine. During the drawing process, advanced lubrication and cooling systems are used to ensure the surface of the copper wires is smooth and the size is precise. For single-core solid conductors, they are directly drawn into copper rods of corresponding diameters; for multi-strand Stranded Conductors, the drawn fine copper wires are stranded according to a certain stranding method and pitch. During the stranding process, it is ensured that each strand of copper wire is evenly stressed and tightly stranded to ensure the conductivity and mechanical properties of the conductor.

The insulation material (PVC or XLPE) is heated and melted by an extruder and evenly coated on the surface of the conductor. During the extrusion process, the extrusion temperature, pressure, and speed are strictly controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, and no defects such as bubbles and pinholes. For PVC Insulation Materials, cooling and shaping are carried out after extrusion; for XLPE Insulation Materials, cross-linking treatment is also required, and the XLPE molecules are formed into a cross-linked structure by heating or irradiation to improve their temperature resistance and mechanical properties.

Outside the insulation layer, the sheath material (PVC or PE) is extruded and coated on the insulation layer through an extruder. The extrusion process parameters are also strictly controlled to ensure that the sheath layer has a uniform thickness, is tightly combined with the insulation layer, and does not fall off. After extrusion, the sheath is cooled, pulled, and other treatments to form the cable.

During the production process, strict inspection and testing are carried out on various properties of the cable. Including the diameter of the conductor, DC resistance test; the thickness of the insulation layer, insulation resistance, withstand voltage test;

Usually, they are packaged in reels. The reel material is hard cardboard or wood, and the appropriate size of the reel is selected according to the length of the cable.

The cable is neatly wound on the reel to avoid twisting and knotting. There are baffles on both sides of the reel to prevent the cable from falling off. The outside of the reel is wrapped with plastic film to play a role in moisture-proof and dust-proof. Each reel is pasted with a clear label, indicating the product name, specification, model, length, rated voltage, production date, batch number, etc.
