Main technical parameter of cable:
- Max. value of conductor DC resistance shall meet the requirement of conductor of category 2 stipulated in GB/T3956 standard at 20℃
- For single core cable without shielding, voltage test of 3.5kV under power frequency is put on for 5 minutes between conductor and water when be immersed in the water for one hour. For multi-core cable, between each insulated conductor and other conductor, voltage test of 3.5kV under power frequency is put on for 5 minutes without puncture of insulation.
