RTV Coatings on Ceramic Insulators: Latest Developments and R&D Needs

The past decades have seen development of a variety of surface engineering techniques and advanced coatings with hydrophobic, self-cleaning, icephobic and anti-corrosion properties. These advances benefit the power industry by reducing risk of insulator flashover due to pollution and icing, corona noise from conductors, fittings and insulators, corrosion of metal components and mechanical problems caused by ice and snow accretion on overhead lines. This presentation deals with RTV coatings applied to outdoor insulation and summarizes key aspects of the information collected in CIGRE WG B2.69, 2021 Brochure while also underlining unresolved issues that deserve additional investigation.
