xlpe insulated power cables have excellent thermal mechanical properties,
excellent electrical properties and chemical resistance,
the utility model has the advantages of simple structure and light weight,
laying is not limited by the fall,
is widely used in urban power grid,
new cables for mines and factories.
crosslinked polyethylene is a chemical or physical method,
crosslinked polyethylene with linear molecular structure of polyethylene into three-dimensional network structure,
thus, the thermo mechanical properties of polyethylene are greatly improved,
and maintained excellent electrical performance.
the maximum rated operating temperature of xlpe insulated power cable conductor is 90,
paper insulated cable,
polyethylene insulated cable,
therefore, the carrying capacity of the cable is further improved.
xlpe cable, simple structure,
allow high temperature, large carrying capacity,
light weight, high-rise buildings in the use of more.
