Insulated Power Cable -XLPE

XLPE insulated power cables are superior in thermomechanical properties, electrical characteristics and chemical resistances. They are not only simple in construction and light in weight but also nolimitation is required to the difference of level in installation along the route. This kind of up-to-date cables is widely used in electrical power nets in cities, mines and factories.

The insulatation of the cable-XLPE is manufactured by adopting a chemical or physical process of cross-linking of the molecular structure. During the process, the cross-linkable insulation is transformed from its linear chain structure into a three-dimensional network structure. Owing to this substantive transformation, the thermomechanical properties of the cable insulation are greatly improved while its superior electrical characteristics remain unchanged.

The maximum permissible continuour conductor operating temperature of XLPE insulated power cables is 90ºC, which is higher than that of paper, PVC, or PE insulated cables. The current rationg of the XLPE insulated cable further increase.
