DESCRIPTION

BS EN 50069:2018


This standard BS EN 50069:2018 High-voltage switchgear and controlgear. Gas-filled welded composite enclosures of cast and wrought aluminium alloys is classified in these ICS categories:
  • 29.130.10 High voltage switchgear and controlgear

This document applies to welded composite enclosures of cast and wrought aluminium alloy pressurized with dry air, inert gases (e.g. 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 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 concerning gas-filled compartments with design pressure higher than 300 kPa 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.
