Quick Details
Product Details
1. Application
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. Standard
IEC 60502, IEC60332, IEC 60754
