High-voltage switchgear and controlgear. Gas-filled welded composite enclosures of cast and wrought aluminium alloys Ingestion-build-59651 plasma arc weldingWhat is this standard about? This document applies to welded composite enclosures of cast and wrought aluminium alloy pressurized with dry air, inert gases (e. g. sulphur hexafluoride or nitrogen or a mixture of such gases), used in indoor and outdoor installations of high voltage switchgear and controlgear with rated voltages above 1 kV, where the gas is used principally for its dielectric and or arc quenching properties with rated voltages: above 1
