High Voltage XLPE Insulated Power Cable upto 400kV Product Details:


XLPE (Cross-Linked Polyethylene) insulated cables have been widely used for electric power distribution of voltage up to 30kV grade since they were developed in 1960 to replace the paper insulated cables and other thermoplastic insulated cables. XLPE cables have many excellent characteristics, especially for use in higher operating temperature. Generally PE insulated cables can be used in maximum operating temperature of 70°C and paper insulated cables in 85°C, but XLPE cables, which have more compact crystallity than PE by cross- linking process, can be used up to 90°C in normal condition.


Thanks to the development of the techniques, the XLPE cable is able to reach 220kV, 345kV and even 500kV.
