High-Voltage Switchgear and Controlgear. Gas-filled wrought steel enclosures Ingestion-build-225643 ISO 20915 is a safetyWhat is this standard about? This document applies to wrought steel enclosures and their welding. These enclosures are pressurized with dry air, inert gases, for example 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 1kV, where the gas is used principally for its dielectric and or arc quenching properties with rated voltages:
