Voltage test:
Each drum of finished cable should withstand power frequency voltage 3.5kV for 5 minutes,the insulation is not breakdown.
Service conditions and operation parameters of Cable:
The cable is applied to fixed installation for rated voltage 0.6/1kV of power transportation and distribution line.
Max. rated temperature of conductor. nominal operating 90°C
Short circuit: max. for 5 sec.250°C
The cable can be laid without drop restriction, and the environment temperature shall not be lower than 0°C.
Standard:
Our XLPE cable can be manufactured according to to IEC 60502,IEC60332,IEC60754.
