This document applies to pressurized compartments (gas-filled compartments with maximum allowable pressure above 50 kPa relative) of AC switchgear and controlgear with rated voltages above 1 kV up to and including 52 kV for indoor or outdoor installations. All gases stable and non-corrosive in the conditions that prevail inside the compartment are covered e.g. gases such as SF6, compressed air, natural-origin gases, alternative fluorinated compounds used alone or in gas mixtures with natural origin gases. The gas or gas mixture being used principally for its dielectric and/or arc-quenching properties.
