Abstract

A gas-insulated switchgear assembly (1) or component of a gas-insulated switchgear assembly is proposed which has an outdoor bushing (6) through which at least one high voltage-carrying conductor (7) is passed. A surge arrester (8) is arranged essentially parallel to the outdoor bushing (6) and is connected to the high voltage-carrying conductor (7) and/or to the top part of the outdoor bushing (6) via a high voltage-side connection piece (9) and to the foot part of the outdoor bushing (6) and/or to the housing of the gas-insulated switchgear assembly or the component of the gas-insulated switchgear assembly via a housing-side connection piece (10).
