| Abstract: | Spacers of a certain 500 kV transmission line were broken. By analyzing the broken surface, chemical compositions and metallographic structure, it is considered that the inner casting defect is the main reason of the spacer broken. Based on the manufacture technology of the spacer, measures to prevent the spacer damage are proposed. |
