The external insulation surfaces of power transmission and distribution equipment are prone to contamination accumulation from industrial pollution, coastal salt spray, and dust-laden environments. When exposed to humid weather, a conductive film forms on the surface, triggering pollution flashover tripping accidents that seriously threaten power grid safety. The anti-pollution flashover coatings and silicone sealing products from Liyang Kangdawei Industrial Co., Ltd. impart hydrophobic properties and insulation protection capabilities to equipment and are widely used for the protection of power transmission and distribution equipment across all voltage levels of the power grid.
