In cases of extreme pollution it becomes necessary to wash traditional glass insulators in order to reduce the risk of flashover in critical conditions.

Composite insulators may be used in such cases, but field experience demonstrates that the benefit brought by composite is often outweighed by difficulties in diagnostics, inspection and live line working.

Sedicoat, the Sediver RTV silicone coated glass eliminates the need of washing in extreme pollution environments, while keeping the inherent properties of toughened glass such as the highest mechanical and electrical reliability and easiness of inspection.
