Using characteristics:
Rated power-frequency voltage U0/U: 48/66kV,64/110kV,76/132kV.
Max. permissible continuous operating temperature of conductor: 90ºC.
Max. short-circuit
temperature of conductor shall not exceed 250ºC(5s maximum duration).
The ambient temperature under installation should not below 0ºC.
The bending radius should not less than 25 times of the cable diameter.
Construction of 66KV XLPE Cable High voltage cable：
Instruction on Cable Construction:
Compact conductor is adopted with compact index over 0.9; 5-section conductor will be used when the cross-sectional area exceeds and includes 1000 mm².
Inner screen consists of semi-conducting nylon strip (double layers for 1000mm² and above) and extruded super-smooth semi-conducting screen.
The insulation is made of super-purified XLPE insulated material.
The insulation screen is made super-smooth semi-conducting material.
YJLW002 and YJLW03 have two layers of semi-conducting waterproof tape with thickness of 0,2mm and overlapped wrapping as buffer layer.
YJLW02 and YJLW03 is made of corrugated aluminum.
The material of outer sheath is 90℃ PVC or PE, whose surface is graphite or synchronous extruded semi-conducting electrode layer with thickness of 0.3~0.4mm.
