Epoxy resin insulating cap

[0020] Such as figure 1 As shown, the present invention is an epoxy resin insulating cap, and the insulating cap is a hollow cylinder with one end open. When the insulating cap blocks the main circuit of the high-voltage switchgear, it often blocks the connection part of the main circuit of the high-voltage switchgear. The connection part of the main circuit of the high-voltage switchgear is provided with a mounting hole for installing the insulating cap. Fitted into the mounting hole of the main circuit of the high-voltage switchgear, the insulating cap isolates the conductive parts of the main circuit from the outside world, improving the insulation of the high-voltage switchgear to the outside world.

[0021] In a preferred embodiment, the outer cylindrical surface of the open end of the insulating cap is provided with an annular boss 1 . When the insulating cap is matched with the sealing ring of the insulating cap, the insulating cap is completely inserted into the seali...
