36/66(72.5)kV CU/XLPE /SAS/PE (or PVC,LSHF) 240 ~ 2000 MM2

The basic material for XLPE is polyethylene, which is chemically transformed to cross-linked polyethylene (XLPE) through the cross-link reaction of organic peroxides. The cross-link method for polyethylene was developed in the United States during the 1950’s and has since been continuously developed for application to higher voltages. Higher voltages are increasingly being required, and the 500kV XLPE cables have already been commercialized.
