 Brief Introduction
to XLPE Insulated Power Cable
Cross-linked polyethylene insulated power
cable not only has excellent electric, mechanical but also has
powerful resistance against chemical corrosion, heataging and
environmental stress. Its structure is simple. The permissible
maximum operating temperature is 90”. It is convenient to use and
can be laid with no restriction of different elevation.
Our XLPE cable can be produced according to our work's
specification which is equivalent IEC60502, and its some
properties required are superior to IEC60502.
We can design and manufacture special XLPE cable according to the
other standards, required by the customers.
