Cable

 

1). Standard: IEC60502; GB/T12706

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) =3.6/6(7.2)-6/10(12)-8.7/15(17.5)-12/20(24)-18/30(36)-21/35(40.5)KV

4). Voltage:

     0.6/1kV, 1.8/3kV, 3.6/6kV, 6/10kV, 8.7/15kV, 12/20kV, 18/30kV, 21/35kV, 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
