At the corners of GIS equipment, a corner shell is usually set to connect with the bushing. The corner shell can be a three-way, four-way, or two-way structure.

[0003] The connection between the existing sleeve and the corner shell of the corner shell usually requires a transition flange to be set between the sleeve and the corner shell. The sleeve is first connected to the transition flange, and then the transition flange is connected to the corner shell flange. In this way, the assembly method between the sleeve and the corner shell is complex in structure, has many parts, and is costly.

[0004] When the corner module is connected to the supporting steel structure, a special cover plate is required for support, or the support is achieved by connecting the connecting holes on the corner shell flange with the connecting bent plate. This steel structure support method has a complex structure, many installation bolts, many parts, and high cost.

[0005] In addition, when the corner shell needs to be connected to the grounding copper busbar, in the related technology, the general practice is to process threaded holes for fixing the copper busbar on the corner shell flange. This method of connecting the copper busbar can easily make the connection between the corner shell flange and the sleeve unstable, making the structure of the connecting copper busbar unstable and unreliable.
