Abstract

Abstract: In order to study the relationship between environmental factors and composite insulator surface hydrophobic characteristic, composite insulator aging process in different conditions is simulated by spray test and immersion test. The surface hydrophobic nature is analyzed by using dynamic contact angle method under different spray time and acid corrosion conditions. Surface morphology of the samples are analyzed in detail by scanning electron microscopy(SEM). The experimental results show that the surface hydrophobic gradually weaken, and may even be completely lost by long exposure to dirty wet environment. Acidic environment have much greater impact on the surface hydrophobic than neutral or alkaline environment because acidic substances have greater influence on the surface compare to neutral or alkaline substances.

Key words: composite insulator, hydrophobic nature, spray time, acid corrosion, surface morphology
