Description
This European Standard applies to cast aluminium alloy enclosures pressurized with dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear above 1 kV, 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.
