01-01-2019
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 switchgear, gas-insulated current transformers, etc.
