Myth About insulating gas Gas In Electrical Equipment

Apr 12, 2021 · 22. How high is the MAC (Maximum allowable working environment concentration) for pure sf6 gas in the substation and how hazardous is pure Sulfr hexafluoride? It is generally recommended that the maximum concentration of insulating gas in the working environment should be kept lower than 1000 μl/l (*). This is the value accepted for a full time (8 h/day, 5 day/week) workGet price

insulating gas-alternative gases for application in gas-insulated

Mar 20, 2018 · The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases.Get price

EP0516053A2 - Dry etching method - Google Patents

A dry etching method whereby an SiO₂ layer and an Si₃N₄ layer may be etched with high selectivity for each other. As etching gas, such sulfur fluorides as S₂F₂ are used which, when dissociated by electric discharges, will form SF x ⁺ as a main etchant for the SiO₂ layer or F* as a main etchant for the Si₃N₄ layer and release sulfur in plasma.Get price
