BS EN 50064:2018 PDF

What is BS EN 50064 about?

BS EN 50064 covers the requirements for the design, construction, testing, inspection, and certification of gas-filled enclosures for use specifically in high-voltage switchgear and control gear, or associated gas-filled equipment. BS EN 50064 applies to wrought aluminium and aluminium alloy 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 control gear with rated voltages above 1 kV, where the gas is used principally for its dielectric and/or arc-quenching properties with rated voltages. BS EN 50064 also covers enclosures of pressurized components such as the centre chamber of live tank switchgear, gas-insulated current transformers, etc.
