Description / Abstract: This guide is based on the knowledge and experience of manufacturers, users, and researchers of room temperature vulcanizing (RTV) silicone rubber coatings that are used to improve the contamination performance of outdoor high-voltage (HV) insulators. This guide discusses various important aspects that are needed for satisfactory long-term performance of high-voltage insulator coatings (HVIC)—namely, various possible application scenarios, maintenance issues on coated insulators, factors affecting long-term performance, the question of aging, laboratory accelerated tests, and functional outdoor evaluation. However, it must be mentioned that for any specific application, judgment, and experience are required to analyze and balance the many characteristics, which are discussed to obtain satisfactory performance and reliability.
