Abstract
Abstract In a pressurized gas insulated switching installation having two branches that can be coupled, through power switches, with a type of bus-bar two-part ring-bar, the two parts of the ring-bar are connected with three power switches connected in series, and between the power switches the connection points for the branches are situated. The poles of the three power switches belonging to one phase are disposed in one common vertical plane and two horizontal planes.
