Product Description


1. Introduction:
Cross-linked polyethylene insulated power cable not only has excellent electric, mechanical properties, but also has powerful resistance against chemical corrosion, heat aging and environmental stress. Its structure is simple. The long term operating temperature is 90oC. It is convenient to use and can be laid with no restriction of different level.
Our enterprise can produce both flame retardant and non-flame retardant series of XLPE power cable.
Our XLPE power cable can be produced according to your specifications, which are equivalent to IEC, DIN, BS and ASTM, and some indexes are surperior to standards stated above.
The flame-retardant cable coves all kinds of low-smoke lowe-halogen, low-smoke halogen free and three classes of A, B ,C.
We can design and manufacture special XLPE cable according to other standards required by the customers, such as Heavy section cut apart conductors, water-resistance, defend termites, defend mouse and so on.
