XLPE Insulated Power Cable

XLPE insulated power cable is used to transmit and distribute power for the power transmission and distribution system of 35kV or lower. It is generally applied in the fields of power, construction, mine, metallurgy, petrochemical industry and communication. It completely replaces the oil immersed paper insulated power cable and partiallyreplaces the PVC insulated power cable.
