Abstract
For high-voltage transmission lines near industrial plants and in areas with coastal weather conditions, insulation contamination strongly affects the reliability of the transmission network. Due to the great importance of insulation in power transmission, it is necessary to increase the reliability of these equipment through various methods. Common
methods include regular washing and lubrication and use of room temperature vulcanized (RTV) silicone rubber polymer coatings. In the meantime, application of polymer coatings perform have been proposed as an efficient method worldwide, due to their very good performance in polluted environmental, resistant to weathering and suspended particles, as well as prolonging the life and reducing the cost of repairing and replacing insulators. In recent years, several reports have been published on the use of nanotechnology to improve the properties of insulators. Today, the use of RTV-based nanocoatings is common in many countries and has brought good results. Therefore, it seems necessary to assess the feasibility, optimization and selection of the appropriate coating to be applied on the insulators installed in different regions of the country are appropriate according to the specific weather conditions of that region. In this article, the solution of adding nanomaterials to solve the problems of silicone rubber polymer coatings applied on high-pressure insulators in the electrical industry is reviewed. The most common nanoparticles used to improve the properties of the coatings, the role of this filler in improving the properties of the coating, and the existing challenges in the uniform distribution of nanoparticles in the polymer matrix are also explained.
