Evaluation of a new protective coating for porcelain insulators

Journal Article · · IEEE Trans. Power Appar. Syst.; (United States)

This paper describes the evaluation of a new elastomeric coating made from a silicone rubber compound for use on porcelain insulators. Field experience has shown that coated insulators have a lower flashover probability under wet contaminated operation than uncoated insulators. Laboratory fog tests also show significant improvements in the wet electrical behavior of clean and contaminated insulators. The Room Temperature Vulcanized (RTV) silicone rubber coating offers both technical and economical advantages for high voltage system operation and maintenance.
