Abstract

The distribution facilities, such as suspension insulator, line post insulator, lightning arrester, COS, used for long periods in the industrial pollution area were investigated. The electrical test and the material analyses were performed on the polluted and non-polluted facilities. The low frequency dry flashover voltage of polluted suspension was decreased about 8% in comparison with non-polluted one. The polluted materials turned out with the iron which came from the foundries. The polluted materials turned out with the iron which came from the foundries. This conductive materials decreased the leakage distance, resulting in reducing of electrical properties.
