6.35/11 kV Al/XLPE/SWA/PVC power cable

Specifications

6.35/11kV AL/XLPE/SWA/PVC medium voltage power cable
1.Standard: IEC60502; GB12706
2.used for electric power transmission

 

6.35/11kV AL/XLPE/SWA/PVC medium voltage power cable:

1). Standard: IEC60502; GB12706.1-2002

2). Application: For laying indoors, underground, in tunnel or cable trench.

3). Specification: 

     * Aluminium conductor for single core or multi-core;

     * XLPE insulated;

     * SWA(steel wire armoured);

     * PVC sheathed power cable.

4). Voltage: 6.35/11kV

5). 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

   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
