Conductor production: After smelting high-purity copper ingots, copper rods are made through continuous casting process, then drawn into
Copper Wires of the required diameter through wire drawing process, and finally multiple copper wires are twisted to form a 120mm² single-core conductor.
Insulation layer extrusion: Using extrusion molding process, XLPE material is heated and melted, then evenly coated on the surface of each conductor to form an insulation layer. During the extrusion process, temperature, speed and pressure are precisely controlled to ensure uniform thickness of the insulation layer. After that, the insulation layer is cross-linked, and the XLPE molecules are formed into a three-dimensional network structure by heating to enhance its performance.
Cabling process: 3 groups of single-core conductors are arranged and twisted according to the dual-group parallel design. During the twisting process, halogen-free materials are filled to ensure the roundness and structural stability of the cable.
Sheath extrusion: A halogen-free sheath is extruded on the outer layer of the cabled cable. The extrusion parameters are controlled to ensure that the sheath has uniform thickness, smooth surface and close combination with the internal structure.
Quality inspection: Strictly inspect the diameter, resistivity and other parameters of the conductor, the thickness, insulation resistance, combustion performance of the insulation layer, and the appearance and mechanical properties of the sheath to ensure that the product meets the standards.
