【 摘 要 】

In this paper, a failure of conductive rod of GIS outlet bushing is analyzed from the connection form, welding quality and microstructure of conductive rod and flange, and it is concluded that the failure of conductive rod is caused by bad welding quality and improper assembly and transportation.
