Outdoor high-voltage switchgear assembly

An outdoor high-voltage switchgear assembly comprising rigid sectionalized busbars provided with busbar compensators made of flexible current-conducting members mounted on insulated supports through the use of bases having an open configuration and electrical apparatuses connected through branches to said sectionalized busbars, each base being composed of legs forming said open configuration in such a way that it is almost U-shaped, wherein said legs are placed in planes parallel to longitudinal axes of the sectionalized busbars, and the base is secured on the insulated support so that the ends of the base legs are higher than the horizontal plane going through the point common for both legs, each busbar compensator being secured by its ends to adjacent sections of the sectionalized busbars, which are attached at the ends of said base legs, and positioned between the longitudinal axes of these legs.
