CU/XLPE/PVC 0.6/1kV Fire Retardant LSZH Power Cable For Buidings
Applications:
It is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable. Power cables for power networks, underground, outdoors and in cable ducting. High voltage xlpe cable is used to be laid indoors, in tunnel, cable furrow or pipe, this cable couldn’t bear mechanical force outside. Laying single core cable in magnetic duct not permissible.
Standards:
International: IEC 60502, IEC 60228, (IEC 60332-3 for FR-type only)
China: GB/T 12706, (GB/T 18380-3 for FR-type only)
Other standards such as BS,DIN and ICEA upon request
