RTV silicone coated glass insulators are suitable for Desert area with mixed pollution, Coastal area with high marine pollution and High pollution area. RTV silicone coated glass insulators do not need washing.

RTV silicone coated glass insulators experience:
18+ years of satisfactory service in harsh conditions without washing
More than 1.000.000 Orient RTV silicone coated toughened glass insulators in service
On T/L up to 500 kV HVAC

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 insulator 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.

RTV silicone coated glass insulators 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.

RTV silicone coated glass insulators operation environments:
Desert area with mixed pollution
Coastal area with high marine pollution
High pollution area
