B-type insulator for insulating and plugging separable connector of gas-insulated switchgear

The utility model discloses a B-type insulator for insulation plugging of a separable connector of a gas insulated switchgear, which relates to the field of insulators of separable connectors and comprises an insulation plug epoxy resin body, and an insulation plug rear metal insert is arranged at the top of the insulation plug epoxy resin body. And the bottom of the inner cavity of the insulating plug epoxy resin body is provided with an insulating plug front metal insert. According to the B-type insulator for insulation plugging of the separable connector of the gas insulated switchgear, the design that the width D1 of the metal insert at the front part of the insulation plug is larger than the width D2 of the metal insert at the rear part of the insulation plug is adopted, and when torque is applied to the metal insert at the rear part of the insulation plug to screw the insulator, the metal insert at the rear part of the insulation plug can be screwed tightly; when the separable connector system is in use
