Middle Voltage 20kv Aluminum Conductor XLPE Insulated Power Cable
1. Description
Construction: Compacted stranded circular aluminum 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 or PE outer sheath.
2. Operating Characteristics
Rated voltage U0/U(Um): 12/20(24)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
