Details: The end of the cable is specially treated with neat cuts and no burrs, which is convenient for connecting with terminals and equipment. During the production of the sheath, the thickness of the sheath is uniform through precise mold control, ensuring the overall quality of the cable.

Wire Drawing: High-purity electrolytic copper rods are drawn through a wire drawing machine in multiple passes to make fine copper wires with diameters of 0.3mm (for 3×1.5mm² cables) and 0.4mm (for 3×2.5mm² cables). During the drawing process, a special lubricant is used to reduce friction between the copper wire and the mold, ensuring a smooth surface and precise size of the copper wire. The drawn copper wire is annealed to eliminate internal stress and improve its flexibility and ductility.

Stranding: The annealed copper wires are stranded on a stranding machine according to the specified number (19 pieces) to form a single-core conductor. During stranding, the stranding pitch and tension are controlled to make the copper wires evenly stranded, and the conductor is round and tight, avoiding defects such as looseness and bulging. The Stranded Conductor is inspected for appearance and size to ensure that it meets the standard requirements.

U1000 R2X PVC Power Station Cable: PVC Insulation Materials are stirred, mixed and dried to remove moisture and impurities. Then, the insulation material is added to the extruder, melted and plasticized at a temperature of 150-180℃, and evenly extruded and wrapped on the surface of the conductor through an extrusion mold to form an insulation layer. The extruded Insulated Wire core immediately enters a cooling water tank for cooling and solidification, and the cooling water temperature is controlled at 20-30℃ to ensure the dimensional stability of the insulation layer.

1000V XLPE Cable: XLPE Insulation Materials need special treatment, pre-crosslinking before extrusion or crosslinking during extrusion. The treated XLPE material is added to the extruder, melted and extruded at a higher temperature (usually 200-250℃), and coated on the surface of the conductor. Then, crosslinking treatment is carried out through a crosslinking pipe to form a network structure of polyethylene molecules, and finally enters a cooling water tank for cooling and solidification.
