    Abstract - (Show below) - (Hide below)

    Pertains to fusion welded wrought steel enclosures pressurized with dry air, inert gases, for example sulfur hexafluoride or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high- voltage switchgear and controlgear with rated voltages 72,5 kV and above, where the gas is used for principally for its dielectric and/or arc-quenching properties.
