Abstract
Standard lightning impulsive dielectric strength tests were performed on cable model samples manufactured with the same technology and the same materials used for high voltage cable application. In particular four different commercial XLPE compounds are considered. Tests were carried out with the aim to investigate the impulsive strength behaviour at room and 90°C of the compounds when they are subjected to both positive and negative testing wave polarities. The results have been compared in terms of Weibull scale and shape parameters. ©2006 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
