This document applies to wrought steel enclosures and their welding.

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:

above 1 kV and up to and including 52 k9 concerning gas-filled compartments with design pressure higher than 300kPa relative pressure (gauge);
above 52 kV concerning all gas-filled compartments.

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.
