400mm2 66kV Underground High Voltage Copper Conductor XLPE Insulated Electric Power Cable
1. Applications:
The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 0.6/1kV~40/69KV.
PVC insulated power cable is suitable for laying fixed in power transmission and distribution lines with A.C. 50HZ and rated voltage of 0.6/1kV.
XLPE insulated power cable has a number of advantages compared with paper insulated and PVC insulated cables. XLPE cable has high electric property, mechanical property, heat aging performance, environmental stress crack resistance, chemical corrosion resistance, and it also has simple structure, convenient operation and it is not restricted by laying in large difference of level. It can be applied in high temperature of 90 degree for a long time.
2. Technology property:
a. Max temperature for Long-time working:≤90°C
b. Installing temperature: ≥0°C
c. Max short-circuit (Not more than5 Sec) temperature: 250°C
d. Unable be laid without the limit of fall with enough mechanical pull,Single core cable can not be laid in iron tube or fixed by circled iron tools around cables
3. Voltage Range:
0.6/1KV, 3.6/6KV, 6/10(11)KV, 8.7/15KV, 26/35KV, 40/69KV...
4. Cores Range:
For Low Voltage cable: Single Core, 2 Cores, 3 Cores, 3.5 Cores, 4 Cores, 5 Cores ...
For Medium voltage cable: Single Core, 3 Cores.
