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. Thermoplastic PE is transformed into thermosetting XLPE. After cross-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent electrical property are still retained.
The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is 90 which resistance is higher than that of 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.
The product is manufactured according to the standard of GB/T12706-2002 "Extruded solid dielectric power cables for rated voltages from l KV (Um=1.2KV) to 35KV (Um=40.5KV)"or IEC, BS, DIN and ICEA upon request.
The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6KV/6KV~26/35KV.
