Detailed Description

Cross-linked polyethylene insulated power cable not only has excellent electric and mechanical properties, but also has powerful resistance against chemical corrosion, heat-aging and environmental stress. Its structure is simple and using conveniently, also can be laid with no restriction of different level. The long term operating temperature is 90, and its transmit capacitance is large.

Our company can produce both flame retardant and non-flame retardant series of XLPE power cable.. Our products can be produced according to our works specifications which are equivalent to GB12706, IEC60502, IEC60332, IEC60754, and its some indexes are superior to standards stated above..

The flame-retardant cable covers all kinds of low-smoke low-halogen, low-smoke halogen free and three classes of A, B, C. We can design and manufacture special XLPE cable according to the other standards require by the customers, such as heavy section cut part conductors, water-resistant, defend termites, defend mouse, and so on..
