When used in breakers (arc extinguishing), SF6 can decompose to many things:
HF, SOF2(SF4), SOF4, SiF4, S2F10(SF5), SO2F2, SO2, SF2, SOF10, S2O2F10, H2S. It can also combine with metals to form CuF2, AlF3, WF6, WO3. I'm probably missing some byproducts, so don't consider this a complete list.
Usually in a sealed tank, the switch contacts are in the tank too. The SF6 gas quenches any arcs that form when the switch contacts are opened.
SF6 (Sulfur Hexaflouride) is the god of gaseous dielectrics. It is a VERY poor conductor, and when it does decompose in an arc, it re-assembles itself in short order. It is also dense, so that it sinks to the floor, and pools in the lowest spot it can get to. This also makes it great in breaking arcs, because it makes it highly thermally conductive, stealing the heat from the arc & diffusing it. SF6 breakers are generally smaller than other types (of the same handling capacity), and therefore lighter. There's nothing we've found better with high voltage. Vacuum is decent. It has fair dielectric strength, can break an arc pretty well. It has one massive advantage over SF6: It is environmentally benign. SF6 is pretty destructive, and has a 3200 year life in the atmosphere. That's tenacity ! So, it has been suggested that if your application is below 36kv or so, you should stick with the VCBs, but you can't beat the handling of SF6 as you go higher.
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.
Sulpur Hexa-Fluoride(SF6) is the gas used to quench the arc in a Vacuum circuit breaker.SF6 is a inert gas and is in-organic,colorless,odorless,non-flammable gas used as an outstanding electrical insolater.AnswerAs its name suggests, the arc is extinguished within a vacuum. No gas is involved.
SF6 circuit breaker
Yes, SF6 is a greenhouse gas.
Sulfur hexafluoride (SF6) is a colorless gas under normal conditions.
A vacuum breaker uses a vacuum to extinguish the arc when interrupting a circuit, while a SF6 gas circuit breaker uses sulfur hexafluoride gas. SF6 gas circuit breakers can handle higher voltages and currents compared to vacuum breakers. SF6 gas circuit breakers are also more environmentally harmful due to the greenhouse gas SF6, while vacuum breakers are considered more eco-friendly.
Usually in a sealed tank, the switch contacts are in the tank too. The SF6 gas quenches any arcs that form when the switch contacts are opened.

Not pure SF6 but it can interact with other molecules under certain conditions to create powder.
SF6---- Sulphur hexa floride
The "6" in SF6 gas represents the six fluorine atoms present in the chemical formula of the gas. SF6 is a colorless, odorless, non-flammable, and non-toxic gas commonly used as an insulator in high-voltage electrical equipment due to its high dielectric strength.
The empirical formula of the gas formed would be SF6, as the reaction between S8 and AgF leads to the formation of silver sulfate (Ag2SO4) and sulfur hexafluoride gas (SF6).
Sulfur hexafluoride (SF6) has a molar mass of 146.06 g/mol. The molar mass of sulfur is 32.06 g/mol. To find the percent composition of sulfur in SF6, you would calculate: (32.06 g/mol sulfur / 146.06 g/mol SF6) x 100 = 22.0%. So, sulfur makes up 22.0% of the mass of SF6 gas.
No, SF6 gas does not have an expiration date or shelf life. However, its properties and effectiveness can deteriorate over time due to contamination or leakage from the equipment where it is used. Regular maintenance and monitoring are necessary to ensure its proper functioning.
