Crosslinked polyethylene insulated power cable has excellent thermal and mechanical properties, excellent electrical properties and chemical corrosion resistance, but also has the advantages of simple structure, light weight, laying is not limited by the drop, etc., is widely used in urban power grid, mines and factories.
The insulation-crosslinked polyethylene of cable is the use of chemical and physical methods to convert the linear molecular structure of polyethylene into a three-dimensional network structure of crosslinked polyethylene, which greatly improves the thermal mechanical properties of polyethylene, so as to maintain excellent electrical properties.
The maximum rated operating temperature of the conductor of the XLPE insulated power cable is 90℃, which is higher than that of the PVC insulated and polyethylene insulated cables, so the current carrying capacity of the cable is further improved.
