  2) Voltage Test

    Each drum of finished cable should withstand power frequency voltage 3.5kv for 5 minutes, the insulation is not breakdown.

 

  3) Service conditions and parameters of cable

     The cable is applied to fixed insulation for rated voltage 0.6/1kv of power transportation and distribution line.

     Max. rated temperature of conductor nominal operating 70oC.

     Short circuit: max. for 5 sec. 160oC.

     The cable is not limited by drop in level when being laid, and the environment temperature shall not be lower than 0oC.

     Perfect chemical stability, resistant against acids, alkalis, grease and organic solvents, and flame resistance.

     Light weight, perfect bending propertied, installed and maintained easily and conveniently.
