33kv Power Cable, Nylon Sheath Anti-Termite, HDPE Sheath, AS/NZS Standard

33KV Compacted Round Copper Conductor Nylon anti-termite HDPE Cable,AS/NZS standard

Description 35KV Compacted Round Copper Conductor Double Steel Tape Armoured Cable

Construction: Compacted stranded circular copper conductor, extruded semi-conducting compound as conductor shield, cross-linked polyethylene (XLPE) insulation, semi-conducting compound as insulation shield, 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 inner covering as armoring bedding, galvanized steel tape armored, PVC outer sheath. 

2.Operating Characteristics 

Rated voltage U0/U(Um): 26/35(40.5)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 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 

3.Application 

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.
