76/132(145) kiloVolt XLPE Insulated Corrugated Aluminium High Voltage Power Cable and wire

76/132(145) kV XLPE Insulated Corrugated Aluminium High Voltage Power Cable

1 Description
Construction: Compacted stranded circular or segmental copper or aluminium conductor, extruded semi-conducting compound as conductor screen, cross-linked polyethylene(XLPE) insulation, semi-conducting compound as insulation screen, semi-conducting water blocking tape, corrugated aluminium sheath, PE or PVC outer sheath.
2 Operating Characteristics
Rated voltage U0/U(Um): 76/132(145)kV
U0 is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
U is the rated power frequency voltage between conductors for which the cable is designed;
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: not less than 20 times of the diameter of cable

3 Application
The cable is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force and certain pulling force.

4 Manufacturing Standards
