The gas-insulated, metal-enclosed switchgear assembly contains two, three or more switchpanels, each having a multipole power breaker (CB1, CB2, CB3, CB4) as well as isolating and grounding switches per switch pole (CB1R) and is designed like a ring or in a 1+E,fra 1/2+EE power-breaker circuit. The switch poles of the power breakers are each of identical design and are arranged parallel to one another. The switchpanels each have one current path of U-shaped design per phase in a vertical plane, in which current path the base of the U contains a vertically aligned pole of the power breaker, and the two limbs of the U each contain an electrical connection of the power breaker and an isolating as well as a grounding switch. The upper limbs of the U of one of the switchpanels are connected phase-by-phase to the lower limbs (Su) of another of the switchpanels, by means of respective single-phase gas pipelines (L12(R), L23(R), L34(Y)) which are arranged inclined to the vertical and are designed in straight lines. Such a switchgear assembly is distinguished by compact construction.
