What is "SF6"?

Sulfur hexafluoride.

SF6 is used by the electrical industry as a gaseous dielectric (insulating) medium for high-voltage (1 kV and above) circuit breakers, switchgear, and other electrical equipment. SF6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. This property makes it possible to significantly reduce the size of electrical gear. This makes GIS more suitable for certain purposes such as indoor placement, as opposed to air-insulated electrical gear, which takes up considerably more room. Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment.

SF6 is used to NOT used inside vacuum breakers to extinguishing the arc. The vacuum bottles that do the actual interrupting contain "nothing" (i.e. "vacuum") Otherwise they'd be called SF6 bottles. SF6 can be used to insulate the HV leads inside the equipment to shrink the physical size and/or weight of the equipment (compared to air or oil insulated equipment)

Arc interrupting equipment that does extinguish the arc in SF6 gas are often referred to as puffer-type interrupters. These are NOT vacuum interrupters.

Yup, it is sulfur hexaflouride, or "sulfur hex" popularly. It is a gas with excellent high voltage insulating properties and is used in such things as high power radar waveguides. The molecule is symmetrical (ball-like, actually) which makes it hard to break up with an electrical field. And, being a Florine compound, it is very chemically inactive.

#A colorless gas soluble in alcohol and ether, slightly soluble in water. A very powerful greenhouse gas used primarily in electrical transmission and distribution systems and as a dielectric in electronics. The global warming potential of SF6 is 23,900.

#Sulfur hexafluoride (SF6) is a gas that consists of one part sulfur and six parts fluorine. It is colorless, odorless, non-toxic, and non-flammable. It is soluble in water and some other liquids. It is generally transported as a liquified compressed gas.

i am not going to the chemical name it is already answered but in engineering terms sf6 is an inert gas its bond is very strong it is used into vacuum circuit breakers to extinguish the flame
