11KV COPPER CONDUCTOR XLPE INSULATED STEEL TAPE ARMORED CABLE

6.35/11kV CU/XLPE/STA/PVC(or PE) Power Cable

1. Description
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, double galvanized steel tape armored, PVC or PE outer sheath.

2. Operating Characteristics
Rated voltage U₀/U(U_m): 6.35/11(12)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;
U_m 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 15 times of the diameter of cable
For three core cable: not less than 12 times of the diameter of cable
When the armored single core cable used for Alternative Current(AC) system, the armored material should be non-magnetic.
