High-voltage switchgear and controlgear. Gas-filled cast aluminium alloy enclosures
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 enclosures 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.
