| Abstract: | In order to reduce the side failure rate of ZnO varistors under energy impact, the high resistance glaze with different formulations was applied on the side of the varistors, and the influence of different high resistance glaze on electrical properties of the varistors was studied. The results show that the suitable high resistance layer with insulation ability and coefficient of expansion matching on the side of the varistors can reduce the defects and increase the uniformity of the varistors, so that the electrical properties of the varistors can be improved. The side failure rate of the ZnO varistors under energy shock is reduced. |
