Abstract：In the humid area like Sichuan Province, chlorococcum often grows abundantly on the surface of post insulators with RTV coat, which may increase the risk of pollution flashover. To address the problem, in this paper, investigations on the growth conditions, the species, the growth habit and the distribution status of the chlorococcum was carried out. Besides, the influence of chlorococcum layer on the hydrophobicity of RTV coat was studied. At last, the switching impulse withstand performance and pollution flashover withstand performance of the chlorococcum polluted insulator were tested. The results indicate that the chlorococcum mainly grows on the top surfaces of the skirts, which will lead to obvious decrease of hydrophobicity of the top surface of the insulator, thus the pollution flashover voltage declines significantly. However, the operating impulse flashover performance is seldom or never affected by the chlorococcum layer.
