FIELD: high-voltage bushings.

SUBSTANCE: bushing has current distributor 1 loaded into high voltage. Current distributor 1 is enclosed by varistor 9. In addition bushing has two current leads 4, 6 of which current lead 6 is connected to high-voltage end and lead 4, to ground; bushing insulator 5 inserted between current distributor 1 and varistor 9; and clamping device 11 that functions to apply contact pressure to varistor 9 disposed between them in several layers. Clamping device has insulating member applying contact pressure to both current leads. Bushing insulator is molded part incorporating bearing member with guide surface for connecting contact 1a of plug connector to cable or electrical equipment lead-in.

EFFECT: simplified monitoring, installation, and maintenance.
