Analysis Of The Reasons Why Insulators Meet The Pollution Prevention Requirements

During long-term outdoor operation, polymer deadend insulator will come into contact with pollutants such as dust and salt particles in the air. The accumulation of dirt will change its electrical characteristics, causing an increase in surface leakage current and the risk of flashover.

By combining the pollution characteristics of different environments with the performance of porcelain dead end insulators material, and optimizing the shape and surface features of suspension insulator, it is possible to mitigate the accumulation of dirt and its impact on the surface electric field distribution. Furthermore, based on multiple experimental data, the geometric parameters of the umbrella skirt are adjusted to maintain relatively stable surface electrical performance under dynamic changes in surface water layers during humid climates.
