Cross-Linked Polyethylene Materials In Medium And High Voltage Cables
As a substitute for paper-insulated cables, cross-linked polyethylene insulated (XLPE) cables have entered the field of power cables quite prevalent internationally. Paper-insulated cables once played a leading role in the power transmission stage. Therefore, after having an impact on its use in the medium-voltage cable category, the stage seems to be shifting to XLPE cables in the high-voltage and ultra-high-voltage range. Especially in the higher voltage field, the monopoly of paper-insulated cables. Such as oil-filled cables or inflatable or compressed cables are gradually disintegrating to coexist with cross-linked polyethylene cables. It has great advantages and economic reasons, such as higher allowable temperature levels, easy connection and maintenance technology, and the omission of equipment inherent in pressurized cables. The insulation material of various types of XLPE cables is low-density (LD) polyethylene. PE is due to its excellent electrical and mechanical pr...
