Claims

[Scope of utility model registration request]

(1) A central conductor held concentrically at the center of a grounded metal cylindrical container, a columnar solid insulating support that supports the central conductor at a distance from the container wall, and a gas filled and sealed inside the container. 1. A gas insulated bus bar comprising an insulating material, wherein the solid insulating support is formed by connecting a plurality of small solid insulating parts having substantially the same shape.

(2) Among the small solid insulator parts, at least one small solid insulator part that is in contact with the center conductor or a metal body having the same potential as the center conductor is made of a material with good heat resistance. A gas insulated busbar according to claim 1 of the utility model registration claim.

(3) The small solid insulating support portion is thicker at the middle than at both ends or has a fin-like projection at the middle.Claim 1 or 2 of the Utility Model Registration Claim Gas insulated busbar as described in section.
