    Abstract - (Show below) - (Hide below)

    Applicable to welded composite enclosures of cast and wrought aluminium and aluminium alloy enclosures pressurized with dry air, inert gases, for example, sulphur hexafluoride, carbon tetrafluoride, or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric and/or arc-quenching properties, with rated voltages: (a) 1 kV and up to and including 52 kV and with gas-filled compartments with design pressure greater than 3 bar (gauge); and (b) 72.5 kV and above. Also covers pressurized components such as the centre-chamber of live tank switchgear and controlgear, gas-insulated current transformers, etc.
