Development of 500‐kV XLPE cables

Lifetime estimation and diagnosis of XLPE used in HV insulation cables under thermal ageing: arithmetic sequences optimised by genetic algorithms approach

“…This excellent insulation material, commonly used in high-voltage cables, is characterised by a very high dielectric strength and low dielectric losses. Despite the excellent mechanical and electrical properties of low-density PE, its thermal behaviour at high temperature and its thermoplastic character limit rather its use especially with the development of new 500 kV cables technology [2][3][4][5]. The use of cross-linked polyethylene (XLPE) overcomes this handicap of PE and maintains its excellent mechanical and electrical properties at high temperatures.…”
