    Abstract: Introduction was made to the development of special tool, a new-type of reducing defect rate of tubular busbar welding. This paper analyzed the cause of defect rate of tubular busbar welding and expounded the improved turning tool, bracket supports and bracket shaft. After the new tool was used to weld the tubular busbar in new project of certain 500 kV substation, the impression defect rate of tubular busbar welding was reduced and the impression quality of tubular busbar welding was good, with favourable economic benefit.
    Key words: substation; tubular busbar; welding; defect rate
