Flame-retardant PVC insulated power cable 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 ***** 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.
