Top level 1x70mm2 power cable

Standards of 1x70mm2 power cable 

1x70mm2 power cable is manufactured according to IEC 60502.2, IEC 60502.1, AS/NZS 1429.1,AS/NZS 5000.1, BS 6622/7835, BS 5467, BS 6746, BS 6346, VDE 0276, ASTM, ABNT etc. It is suitable to be installed in the power line with rated voltage from (U0/U)0.6/1kV to 19/33kV for power transmission.

 

Applicationof 1x70mm2 power cable

1x70mm2 power cable is applied to transmit and distribute power in power transmission and distribution system of 1kV~35kV or lower. It is widely adopted in the fields including power, construction, industry, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power  cable and in partial re-place of PVC insulation or XLPE power cable.


The maximum rated temperature

XLPE insulated,the maximum operating temperature of conductor shall exceed 90℃when the cable is used for long not period. The temperature of conductor shall not exceed 250℃ at short circuit for 5 seconds.

PVC insulated,the maximum operating temperature of conductor shall exceed 90℃ or 70 ℃  when the cable is used for long not period. PVC insulated the temperature of conductor shall not exceed 160℃ at short circuit for 5 seconds.

 

Installation requirement

The installation of cable is not limited by the difference of elevation along the route. The ambient temperature should not be below 0℃ during installation. The permissible bending radius for cable shall be complied with the following regulations:

For single-core: R>20(D+d) +/-5%

For multi-core: R>15(D+d) +/-5%

Where:R—bending radius (mm) , D—overall diameter of the cable (mm) , d—diameter of conductor (mm).

Single core cable of using in AC circuit shall be without armour or with steel wire armour and shall not be laid in magnetic ducs.
