    Abstract: The variable diameter barrel bus effectively uses the insulation margin in the middle of busbar and adopts the welding form of 5 series formed pipe and casting, with the characteristics of low component cost, high standardization and high production efficiency. This paper carried out the comparison of conventional straight edge line barrel structure and variable diameter busbar barrel structure, gave the design plan of variable diameter busbar barrel and demonstrated the feasibility of variable diameter barrel busbar from five aspects including the insulation strength, the mechanical strength, the welding technology, the temperature rise test and the internal fault arc test, combining the theoretical calculation with the experimental verification, which is good for the engineering application.
    Key words: variable diameter barrel; insulating strength; mechanical strength; welding technology
