hv sf6 n2 protective Instrument
To replace SF6 in high voltage equipment such as GIS, AIS or instrument transformers, GE proposes its g3 gas mixture based on fluorinitrile and CO2 as an alternative insulating and switching gas. SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc quenching medium.

hv Sulfur Hexafluoride switch explain
Chemical formula: SF₆Melting point: −64 &C; −83 &F; 209 KMolar mass: 146.06 g/molSolubility in water: 0.003% (25 &C)OverviewSulfur hexafluoride (SF6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. 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.

Asia insulating gas Purpose Disadvantage
Thermal insulators work by trapping bubbles or pockets of gas inside a foam structure. When these cells of gas are filled with moisture, there are significant losses in insulating efficiency. The thermal conductivity of water (at 10 &C) is 0.5 kcal m 1 h 1 &C 1 and that of ice (at 0 &C) is 2 kcal m 1 h 1 &C 1 (about four times the value of water).
