Cross-linked polyethylene(XLPE) insulation cable have been suppied by Wuxi City Greatwall Wire & Cable Co., Ltd for many years and incessant effort of developments in cable design and manufacturing techniques, enables Changchen to supply XLPE insulation cable for voltage up to 220kv.

This catalogue provides constructional and technical information on cables for the voltages Uo/U(Um) as follows: 0.6/1kv, 1.8/3(3.6)kv, 3.6/6(7.2)kv, 6/10(12)kv, 8.7/15(17.5)kv, 12/20(24)kv, 18/30(36)kv

The structure of XLPE insulated cables, listed in table hereinafter, is the representative one from IEC60502, other type of cables and extra high voltage cable, not listed in this catalogue, can also be offered upon request

XLPE, Cross-linked polyethylene, has stable intermolecular bonds between polyethylene particles created by thermochemical action, due to the presence of organic peroxide.

XLPE has the same electric properties as the conventional polyethylene and, as a result of stable intermolecular bonds, has much better thermal and mechanical properties. This provides XLPE insulation cables to be used at maximum continuous conductors temperature of 90 degree cetigrade while conventional polyethylene insulation cable to be used at that of 75degree cetigrade. This provides an important advantage in cable ratings and is of special significance in countries or situations where the ambient temperature is high and derating factors have to be applied.
