Abstract

For high-voltage transmission lines near industrial operations and in areas with coastal air and water conditions, insulation contamination significantly affects the reliability of the transmission system. , there is a need to increase the reliability of this equipment through various methods. Common methods include regular washing and lubrication and the use of silicone rubber polymer coatings (RTV), of which polymer coatings perform very well in dirty environments, are resistant to weathering and suspended solids, and also have a longer service life. Extending the service life and reducing the cost of repairing and replacing insulators is considered an efficient method worldwide. In recent years, several reports have been published on the use of science and nanotechnology to improve the properties of insulators. The use of RTV-based nanocoatings is now common in many countries and has produced good results. Therefore, the feasibility, optimization and selection of the appropriate coating to be applied on the insulators installed in different regions of the country are appropriate. The weather conditions specific to each area seem to play a role. In this article, a brief overview of the addition of nanomaterials to solve the problems of silicone rubber polymer coatings on high-pressure insulators in the electrical industry has been presented, and the most common nanoparticles used to improve the properties of the coatings, the role of this filler ‌ in changing the properties of the coating, and the existing challenges in the uniform distribution of nanoparticles in the polymer area have been examined.
