XLPE Insulated Power Cable

XLPE Insulated Power Cable

XLPE insulated power cable is used totransmit and distribute power for the power transmission anddistribution system of 35kV or lower. It is generally applied in thefields of power, construction, mine, metallurgy,petrochemical industry and communication. It completely replaces the oilimmersed paper insulated power cable and partiallyreplaces the PVCinsulated power cable.
