Flame-resistant power cable with xlpe insulated not only has excellent electric, mechanical properties, but also has powerful resistance against heat aging, environmental stress and chemical corrosion. Its structure is simple and convenient to use and can be laid with no restriction of different elevation.The permissible maximum operating temperature is 90. Our XLPE cable can be produced according to our company standard which is equivalent IEC60502. We can design and manufacture special XLPE cable according to the required by the customers.
 
   Executive standard
1)GB/T12706.1-2002(Equivalent IEC 60502)
 Rated voltage 1kv (Um=1.2kv)and power cable
2)GB/T12706.2-2002(Eqquivalent IEC60502-2)Rated voltage6 kvUm=7.2kv and Um=36kv power cable
3)G/BT12706.3(VOLTAGE Grade Overtep IEC 60502-2) Rated Voltage3.5V Um=40.5kv and power cable.
Working consitions:
