BS EN 50052:2016

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

Status : Confirmed, Current   Published : December 2016



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.
