2017/8/243. 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.

Early detection of SF6 leaks not only reduce the emitted amount of harmful greenhouse gases but also allows for optimized maintenance actions. Our sophisticated cameras are specifically tuned to a very narrow spectral range in the order of hundreds of nanometers, and are therefore selective to the particular gas of interest.

As SF6 is not only an excellent insulation gas, it has also the highest known global warming potential, about 22,800 times that of CO2. Hence, gas losses have a high impact on the environment, which makes it necessary for OEMs to apply state of the art sealing technologies, highest standards of material and guarantee most reliable testing methods.

2018/4/19The level of humidity in SF 6 insulated switchgear must be kept below its water saturation point.If the gas is too humid, it loses some of its insulating properties; corrosion and dangerous leaks can also occur. A complete SF 6 handling instrument monitors the quality of the gas, dries it out when wet, and replaces it safely when necessary, thanks to a sulfur hexafluoride tank.

Physics of Conduction in SolidsUsesInsulation in Electrical ApparatusTelegraph and Power Transmission InsulatorsInsulation of AntennasSee AlsoReferencesElectrical insulation is the absence of electrical conduction. Electronic band theory (a branch of physics) dictates that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal. If no such states are available, the material is an insulator. Most (though not all, see Mott insulator) insulators have a large band gap.
