Problems solved by technology

[0005] In the natural environment, various dust particles in the atmosphere are attracted by the electric field force or gravity when passing through the insulator, and are deposited on the surface of the porcelain insulator, and the surface of the porcelain insulator is a hydrophilic glaze, and the surface smoothness is not enough. The surface is easy to accumulate dirt, and the shape and structure of porcelain insulators are also easy to affect the airflow when the wind blows, which usually leads to the accumulation of various flying dust
