Standard
The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is 90 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.
For XLPE insulated power cable ,either chemical method or physical method is employer to transform the molecular structure of PE form chain into three-dimensional network, i.e. thermoplastic PE is transformer into thermosetting XLPE. After cross-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent property are still retained.
