Our solution : pure air insulation for AIS and GIS switchgear Confidential Property of Schneider Electric | Page 11 Pure air is the best insulating medium for MV switchgear: •P= 1,4 bar abs for 12 kV •P = 2,5 bar abs for 24 kV parallel vacuum interruption technology enables: •Safe, compact and cost-effective 3 positions load break switch

Gas-insulated switchgear (GIS) has solved many problems by providing a far safer and more compact solution. The only significant drawback has been the use of SF6 gas, which requires very careful handling to avoid environmental issues. That drawback has been greatly reduced with AirPlus gas, now available in ABB

May 25, 20203. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.

Differences between the gas mixtures are mainly in the boiling point and the GWP. Keywords: SF6 alternative gases, CO2, Circuit Breaker 1. Introduction SF6 is widely used in electric power transmission and distribution systems, as for example in gas insulated switchgear (GIS), circuit breakers (CB) and medium voltage (MV) load break switches. It

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay.Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit.Advantages over other media include lower operating noise and no emission

Gas-insulated switchgear (GIS) Complete portfolio for all applications and environments Gas-insulated high-voltage switchgear (GIS) is a compact metal encapsulated switchgear consisting of high-voltage components such as circuit-breakers and disconnectors, which can be safely operated in
