摘要

An actuating device for an electric switchgear of the type having one or more bushings connected to a casing. The actuating device can include a gear mechanism which is suitable to be mounted at and outside the zone where a bushing is connected to the casing, and which includes a plurality of gears operatively interconnected to each other and arranged to move a bushing between a first service position and a second transport position wherein it is lowered towards the casing from the first service position. A connection can be arranged to keep the bushing operatively coupled to the casing while moving it between the first and second positions.
