Baicheng 110kV cable extrusion line is a catenary continuous vulcanization line (CCV line) for production of high-grade XLPE insulated power cables up to 110kV. This cable production line carries out triple extrusion process of inner semiconductor layer, insulation layer and outer semiconductor layer in one pass. Our 110kV cable triple extrusion line mainly consists of extruders, crosshead, pay-off stand, accumulator, capstan, take-up stand, etc.
With the use of this CCV line, XLPE insulated power cables can be manufactured in diverse sizes, diameters, lengths, layer thickness and other technical specifications, and suitable for various applications including direct laying in the ground, burying in underground ducts, submerging under water and working on overhead transmission systems.
