XLPE Medium Voltage Cables MV Copper Conductor SWA 33kV X 70mm2 X 3 C

1. Introduction

For XLPE insulated power cable, either chemical method or physical method is employed to transform the molecular structure of PE from chain into three-dimensional network, i.e. thermo-plastic PE is transformed into thermosetting XLPE. After cr·oss-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent electrical property are still retained.

The maximum permissible operating of the conductor of a XLPE insulated power cable is 90°C.which is higher than that of paper, PVC or PE insulated power cable. The cable has the advantage of simplicity in construction, lightness in weight, convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.
