Development of anti-icing coatings applied to insulators in China / Xiaoxing Wei in IEEE electrical insulation magazine, Vol. 30 N° 2 (Mars-Avril 2014) 

Public ISBD [article]  in IEEE electrical insulation magazine > Vol. 30 N° 2 (Mars-Avril 2014) . - pp. 42 - 50 Titre : Development of anti-icing coatings applied to insulators in China Type de document : texte imprimé Auteurs : Xiaoxing Wei, Auteur ; Zhidong, Jia, Auteur ; Zhenting Sun, Auteur Année de publication : 2015 Article en page(s) : pp. 42 - 50 Note générale : Génie électrique Langues : Français (fre) Mots-clés : Coating  techniques  Ice  Power  transmission  lines  Silicone  rubber  insulators Résumé : Icing of transmission lines due to extreme weather conditions has caused many failures in power networks worldwide [1]. As China has much of its land 2,000 m above sea level, intense snow and ice storms at this altitude have caused significant losses to the economy, and the harsh conditions have made life very difficult in these regions [2]. The winter of 2008/2009 was particularly harsh with freezing rain, which continued for more than three weeks in the central provinces, causing 218 ice flashovers. In particular, Hunan and Jiangxi Provinces experienced the severest storms resulting in damage to 37% of the 500-kV power transmission towers, collapsing many towers. Considerable work has been done in China on understanding the reasons for, and preventing, the icing flashover of insulators [3]-[10], but in this article the various anti-icing and de-icing methods for insulators currently being investigated in China are discussed with particular reference to the application of semiconductive silicone rubber coatings on insulators.
