Wholesale Power Electric Cable With XLPE Insulated 
Technical Parameters of our Power Cable 
1). Standard: IEC60502; GB/T12706;IEC 60840;IEC62067;GB/T 11017;GB/Z 18890
2). Detailed description or construction:
    * Conductor: compacted or uncompacted copper or aluminium
    * Insulation: Cross-linked polyethylene (XLPE) or Polyvinyl chloride (PVC)
    * Filler: Polypropylene filament with lapped binding tape
    * Binder: Binding tape
    * Inner sheath: Polyvinyl chloride (PVC)
    * Armour: Galvanized steel wire armored (SWA) or steel tape armored (STA)
    *Sheath: Polyvinyl chloride (PVC)
3). The rated voltages U0/U(Um) of the cables considered in this standard are as follows:
    U0/U(Um) =0.6/1(1.2)-3.6/6(7.2)-6/10(12)-6.35/11(12)-8.7/15(17.5)-12/20(24)-12.7/22(24)-18/30(36)-19/33(36)-26/35(40.5)KV
4). Voltage:
     0.6/1kV, 1.8/3kV, 3.6/6kV, 6/10kV,6.35/11kV, 8.7/15kV, 12/20kV,12.7/22kV, 18/30kV,19/33kV,26/35kV
    In the voltage designation of cables U0/U(Um):
        * U0 is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
        * U is the rated power frequency voltage between conductors for which the cable is designed;
        * Um is the maximum value of the "highest system voltage" for which the equipment maybe used.
5). Application:
     For laying indoors, in tunnel or cable trench with large difference of level able to bear external mechanical forces.
6). Marking: According to the customers" requirements
7). Nominal cross-sectional areas:
1.5mm2, 2.5mm2, 4mm2, 6mm2, 10mm2, 16mm2, 25mm2, 35mm2, 50mm2, 70mm2, 95mm2, 120mm2, 150mm2, 185mm2, 240mm2, 300mm2, 400mm2, 500mm2, 630mm2, 800mm2
