Coating for improvement of electrical performance of outdoor insulators under pollution conditions

The Technical Brochure presents the state of art of Room Temperature Vulcanizing (RTV) insulator coating, as used both to mitigate pollution flashovers on insulators with demonstrated poor service performance and as a viable solution at the design phase itself, with the adoption of factory pre-coated insulators. Based on more than 30 years experience, guidelines for RTV coating procedures, for laboratory testing to verify the product quality and for  diagnostics to assess the insulator field conditions are reported in the TB.
