RTV Anti pollution flashover coating with good perfoamance


Production Features


Anti-pollution flashover coatings is a new type silicone coatings. It can be long-term stored in sealed container and cured by absorbing moisture in the air. This product is neutral, has good adhesion performance to insulator, excellent electrical insulation performance, resistance to damp, resistance to corona. Besides, the cured coating has excellent migration performance of hydrophobicity, resistance to UV, rain and hail, excellent outdoor aging resistance performance and long service life. It is mainly used for high voltage line insulators surface of external insulation.

1.Low viscosity, easy to spray, strong operability

2.Good migration performance of hydrophobicity, resistance to water and damp

3.Excellent electrical insulating performance and aging resistance performance


Advantages of RTV coating


Our RTV coatings work on the principle of providing a hydrophobic surface limiting the leakage current to harmless levels in the presence of moisture and contamination.
Excellent self cleaning characteristics and long-term resistance to weathering and diffcult environments
> Long-term hydrophobicity due to the migration of low molecular weight (LMW) siloxanes into the pollution layer
> Suppression of leakage current, discharges and pollution flashover
> Reduced maintenance expenditures, as in washing, compared to conventional insulator surfaces
> Facilitated cleaning in case of extreme pollution deposition (e.g. cement); even most diffcult pollutants can be wiped off by cloth
> RTV coated surfaces withstand high pressure jet washing up to 90 bar (normal application, 25cm distance)
> The best of both worlds, mechanical strength of porcelain and pollution performance of silicone rubber
> Long-term RTV stability makes repeated application of grease unnecessary
> Minimum 15 years as experienced and reported by STRI
> Non toxic and environmental friendly material
> Transmission reliability as well as environmental and resource conservation by effciently utilizing generated power
RTV silicone coating can also be applied in normal contaminated areas, thus reducing maintenance expenditures and revenue losses because of required station shut downs for insulator washing.


Operation


1.Use dry cloth to clean the surface of insulator before using, then it can be operated in good weather.

2.Spray on clean and dry surface when operating, the coating thickness should be over 0.25mm, holidays should be avoided.

3.The tack free time would be about 30 minutes, and the completely cured time would be 24 hours after operation.
