This European Standard applies to welded wrought steel enclosures pressurised 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.- above 1 kV and up to and including 52 kV and with gas-filled compartments with design pressure higher than 300 kPa relative pressure (gauge); - and with rated voltage above 52 kV. The enclosures comprise parts of electrical equipment not necessarily limited to the following examples: - circuit-breakers; - switch-disconnectors; - disconnectors; - earthing switches; - current transformers; - voltage transformers; - surge arrestors; - busbars and connections; - etc. The scope also covers enclosures of pressurized components such as the centre chamber of live tank 118 switchgear, gas-insulated current transformers, etc.
