Abstract: The solid ring main unit should be provided with all insulation and all the exposed electric conductors have to be protected by insulation plugs. This paper researched on the problems of possibly retention bubbles on interface and the installation difficulty of 12 kV solid-insulated ring main units plugs, analyzed the installation location of insulation plugs, insulation structure and causes of problems, and designed the new-type plugs. The electric field simulating calculation verifies the feasibility of the mentioned solution.
Key words: solid ring main unit; insulation plug; electric field analysis; structural design
