  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 90oC.
     Short circuit: max. for 5 sec. 250oC.
     The cable can be laid without drop retriction, and the environment temperature shall not be lower than 0oC.
