Key Ways To Improve The Pollution Resistance Of Insulators

In highly polluted environments, the tension insulator used in power systems is highly susceptible to the accumulation of salt spray, dust, and moisture. Once a conductive film forms on the dead end insulators surface, its leakage current increases, potentially triggering flashover. To improve the anti-pollution level of dead end suspension insulators, the following measures should be taken:

Select a coating material with hydrophobic properties to make it more difficult for pollutant particles and moisture to form continuous conductive paths on the polymer deadend insulator surface.

Optimize the actual operating structure of porcelain dead end insulators by extending the creepage distance or changing the external geometry to slow down the rate at which the contamination layer forms conductive paths.
