Bushing Boot & Bellows for Switchgear
Bushing Boots are non-tracking elastomeric insulating boots used with terminations, fitting over switchgear bushings to insulate right-angle or straight bushing connections up to 25 kV; Bellows are flexible PVC components used for cable ducting in low-voltage switchgear and transformer industry.

Dimensions & Drawings
Bushing Boots are non-tracking elastomeric insulating boots used with terminations, fitting over switchgear bushings to insulate right-angled or straight connections up to 25 kV and enhance phase-to-phase and phase-to-earth insulation, protecting against flashover or induced surges.
Bellows, in flexible PVC, handle cable ducting in low-voltage switchgear and transformer equipment, in shapes and sizes matched to different mounting options.
