Cu conductor XLPE insulated PVC sheathed power cable

The cable is manufactured according to GB/T 12706-2002(equal to IEC 60502-1997), suitable to be installed in the power line with rated voltage from U₀/U3.6/6 kV to 26/35 kV for transmitting electricity. 

1. Maximum rated temperature

The maximum operating temperature of conductor shall not exceed 90^oC when the XLPE insulated cable is used for long time. The temperature of conductor shall not exceed 250^oC at short circuit. The max. duration does not exceed 5 seconds.

2. Installation requirement

The installation of cable is not limited by the difference of level along the route .The ambient temperature should not be below 0^oC during installation. The permissible bending radius of cables shall not be less than 20 D for single-core cable and 15 D for three-core cable respectively, D is the cable overall diameter.

 The single-core cable shall be non-armoured or metal wire(including steel wire or non-magnetic metal wire) armoured or non-magnetic metal tape armoured , when it is electrified with alternating current and shall not be laid in magnetic ducts.

Note: The current-carrying capacity is just 60% compared with single-core cable of the same specification for non-armoured or else non-magetic metal armoured if the single-core steel armoured cable is chosen.
