Coating process of silicone rubber anti pollution flashover coating

With the development of urban and rural industrial and agricultural production, environmental degradation, voltage rise and network expansion, the power grid pollution flashover accidents continue to increase [1]. The surface of outdoor equipment of power system natural product pollution phenomenon is inevitable, in wet conditions (such as fog, dew and rain) equipment insulation level greatly reduced. Therefore, under the conditions of normal operation occurred surface flashover, pollution flashover, general the flashover voltage is up to 20% of the normal value of the pollution flashover can be caused by a power outage. In the last few years, pollution flashover occurred in the transmission line in many power grids, such as the February 22, 2001, in Liaoning, Henan, Hebei, and the area of Beijing, Tianjin and the area has been a large area of pollution flashover. Silicone rubber anti pollution flashover coating (RTV) has excellent resistance to the advantages of temperature characteristics, dielectric, weatherability, hate water, coating process simple, especially it has excellent hydrophobic migration. In the insulator surface coated with a layer of RTV coating, can greatly improve the pollution flashover voltage and prevent the natural product contamination and wet conditions, the porcelain insulator occurs surface flashover and ensure the safe operation of power grid.
Usually RTV coating main spraying inorganic material surface of the insulator and high surface energy, with a strong adhesion; but organic low surface energy and surface coating, if handled improperly, happen to fall off phenomenon, such as a unit of electrical products have repeatedly occurred RTV coating blistering and shedding of phenomenon.
