3X70+2X35mm2 Copper XLPE Insulated PVC Sheathed Power Cable
Product Description
1. Applications
This product is applied to the fixed installation, power transmission and power distribution circuit of rated voltage 35KV and below.
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.
