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.
