What is BS EN 50052 ‒ Gas-filled cast aluminium alloy enclosures about?
BS EN 50052 is an international standard that covers guidelines for the high-voltage switchgear and controlgear. BS EN 50052 applies to cast the aluminium alloy enclosures pressurized with dry air, inert gases, like 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. 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), with rated voltage above 52 kV
