220kV sf6 gas Arc extinguishing Status quo

SF6 is a non toxic, inert and electronegative gas, heavier than air, offering very effective arc extinguishing performance, along with the above mentioned high insulation capability. In the case of high temperature arc produced by circuit breaking, SF6 gas will resolve into subfluorides.

500kV Rules Disadvantage

2016/5/27If the rules say this is ok, then to counter the installation you'd have to fight and prove their standards are too high. This is something I would expect they'll fight tooth and nail as it would pull into question every house that currently is already so close that there is cause for concern.

2014/11/103. 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.

35kV insulating gas Gas tank Development trend

2018/3/12Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6 ) is the main gas used in these types of transformer at present although other gases are under development.

It is inorganic, colorless, odorless, non flammable, and non toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earth's troposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugitive emissions from banks of SF 6 gas contained in its medium and high voltage switchgear. Uses in magnesium, aluminum, and electronics manufacturing also hastened atmospheric growth.
