Iranian Company Makes RTV Silicon Nanocoatings to Protect High-Voltage Insulators

TEHRAN (ANA)- Iranian experts at a knowledge-based company managed to manufacture RTV silicone nanocoatings to protect the high voltage insulators from pollution and humidity and increase their lifespan.

“The product we have made is RTV silicone coatings, which are mainly used in the power industry. These coatings are applied as self-cleaning, hydrophobic and anti-fouling coatings on the equipment,” said Monireh Taqvayee, the managing director of the company.

“Insulators are made of silicone, glass and ceramic. Silicone insulators have a short lifespan but they are suitable for polluted environments. Ceramic and glass insulators enjoy high strength but they quickly face problems in polluted environments,” she added.

“In this product, we used the advantage of both parts by creating a silicon nanocoating on the surface of the insulators,” Taqvayee stated.

Noting that the silicone nanocoating with hydrophobic properties protects insulator against harsh environment and pollution, she said, “This coating can remain on the surface of ceramic and glass insulators for years, and even after damage which is caused by power outages, re-coating the insulator is possible.”

“We have launched the production line of this product, which has the capacity to produce 300 tons per year,” Taqvayee said, adding that the regional power companies, petrochemicals, steel and cement factories, and companies facing fine dust problems are the customers of this product.

RTV silicone high voltage insulator coatings provide superior arcing and flash over protection in the most hostile environments.

It lasts longer than other coatings, washing and greases, providing significant savings in maintenance and replacement costs.

The RTV silicone coating generally leaves insulators virtually maintenance free for many years.
