Standard and Property for Using
The XLPE insulated power cable can be produced according to our factory specification with the standard IEC60502. The factory can also design and manufacture special XLPE cable according to the other standards required by the customers. They not only have excellent electric, mechanical properties, but also have powerful resistance against chemical corrosion, heataging and environmental stress. Their structures are simple. The permissible maximum operating temperature is 90C. It is convenient for using, and they can be laid with no restriction of different elevation.
