Abstract

Coating of room-temperature vulcanized (RTV) silicone rubber is increasingly being used by power transmission utilities. This is to overcome the contamination problems encountered in porcelain and glass insulators particularly under wet conditions. In order to experimentally evaluate the coated RTV silicone rubber in this paper, a clean fog chamber has been fabricated and a data acquisition system (DAS) has been prepared to conduct tests on insulator samples. The electrical performance of the RTV silicone rubber insulator coatings in the clean fog chamber has been experimentally investigated. The influences of coating thickness and pollution level on the leakage current were investigated.
