Sf6 Gas Processing Equipments - vpiltd.com

Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. SF 6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.Get price

Toxicity.- sf6 gas is odorless, colorless,tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is reduced from 21 percent to less than 13 percent, suffocation can occur without warning.Get price

Sulfr hexafluoride is the most used insulating gas, it works by quenching arcs as contacts of insulating gas switchgear are opened closed during the normal use of switchgear. In fact when the arching takes place there is so much energy in that arc that the Sulfr hexafluoride molecules actual y break apart into sulfur fluorinates. When the sf6 gas is very pure the sulfur fluorinates canGet price
