During construction, appropriate lengths can be cut according to needs, reducing the waste of conductors, and is also convenient for transportation and storage.
Copper Purification: High-quality blister copper is selected as the raw material and purified by electrolytic refining. In the electrolysis process, blister copper is used as the anode and pure copper as the cathode. Under the action of direct current, copper ions in the blister copper move to the cathode and deposit, while impurities remain in the electrolyte or form anode slime. By precisely controlling the temperature of the electrolytic cell, current density, electrolyte composition and other parameters, the purity of copper can reach more than 99.95%, obtaining high-purity electrolytic copper, which lays a good foundation for subsequent processing.
Copper Wire Drawing: The purified electrolytic copper is processed into copper rods, and then the copper rods are drawn into single-strand copper wires by a wire drawing machine. During the drawing process, the copper rod passes through a series of dies with different apertures and is gradually drawn to the required diameter. During the drawing process, the copper wire needs to be cooled and lubricated to prevent the copper wire from performance degradation or surface damage due to overheating. Cooling usually adopts water cooling or oil cooling, and lubrication uses special wire drawing lubricants to reduce friction between the copper wire and the die, ensuring that the diameter of the single-strand copper wire is uniform and the surface is smooth.
Multi-Strand Stranding: 7 drawn single-strand copper wires are stranded by a stranding machine to form a 7-stranded copper conductor. During the stranding process, it is necessary to set an appropriate stranding pitch according to the design requirements.
