Performance Analysis of Self-cleaning Hard Coating on Insulators after Trial Operation

摘要：

　　SCHC is a new kind of insulator coating designed to enhance the pollution flashover voltage,and more importantly,to reduce contamination accumulation on insulators.SCHC has good performance in laboratory,but its operating effect has not been studied.In this paper,sample insulators with SCHC coating having operated for a year are tested concerning its hydrophobicity,NSDD,ESDD,and voltage withstanding capability.The result shows that the hydrophobicity doesnt change after a years operation and contamination accumulation on SCHCs surface is much less than that on the RTVs surface.The SCHC has better performance than RTV overall and still needs to be improved in the future.
