Introduction of 26/35KV XLPE/PVC Power Cable
Construction: Compacted stranded circular copper conductor, extruded semi-conducting compound as conductor screen, cross-linked polyethylene(XLPE) insulation, semi-conducting compound as insulation screen, copper tape or combination of copper wire and tape as metallic screen, three cores assembled together with non-hygroscopic polypropylene filler, wrapped with binder tape, PVC or PE outer sheath.
Characteristics of 26/35KV XLPE/PVC Power Cable
Um is the maximum value of the “highest system voltage” for which the equipment may be used.
Max. permissible continuous operating temperature of conductor: 90 °C;
Max. temperature of conductor during short-circuit (5s max. duration) shall not exceed: 250 °C;
The ambient temperature under installation should not be lower than: 0 °C.
The bending radius of cable is recommended as following:
For single core cable: not less than 20 times of the diameter of cable;
For three core cable: not less than 15 times of the diameter of cable.
Application of 26/35KV XLPE/PVC Power Cable
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel or in cable trench, unable to bear external mechanical force.
Single core cable in magnetic duct is not permissible.
Manufacturing Standards of 26/35KV XLPE/PVC Power Cable
