Abstract

The worn ball head hanging ring used in suspension insulator of 110kV transmission line was investigated by means of microstructure analysis, Macro-morphology inspection, fracture morphology analysis and hardness test. The results show that the material of the ball head hanging ring with low hardness and poor wear resistance and the galloping of the conductor were the main reason for its severe wear. Additionally, effective suggestions were put forward in order to improve the wear resistance of the ball head hanging ring in order to ensure the safety and stability of the power grid.
