The product is composed of tight conductor, weather resistant insulation and corresponding semi conductive shield, which has the mechanical property of the overhead line, and the safety transmission characteristic of the power cable. Compared with the bare wire, has small spacing erection, high safety and reliability, ageing resistance and other excellent performance characteristics, is preferred by varieties of city and town cable transmission engineering.
Standard: GB12527-90 (reference to international IEC502, IEC227 standards)
Conductor: copper or aluminum
Cable diameter less than 25mm should be not less than 4D
The cable diameter 25mm and above shall be not less than 6D
Temperature range: 0 - 90℃
Partial discharge experiment:
10kV cable insulation shielding dipped in water and the applied voltage is 9kV, the discharge amount of the cable is not greater than 20pC.
PVC insulated overhead cable is suitable for aerial fixed installation, as service drop wire, only used in 0.6/1KV voltage level. During cables operation, can not frequent contact with trees.
0.6/1kV two core copper / aluminum conductor PVC insulated overhead cable parameter:
