Sulfur hexafluride (SF6).
SF6 is colorless
That would be sulfur hexafluoride. It is a very useful gas, but it's also the most potent greenhouse gas there is.
There is one sulphur, and 6 fluoride (hence the name HEXAfluoride.) Hope this helped! ^^

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.
Sulfur hexafluride (SF6).
Not pure SF6 but it can interact with other molecules under certain conditions to create powder.
SF6---- Sulphur hexa floride
The neutral SF6 molecule has no dipole moment. The gas phase SF6- ion is not that well understood- on the basis that the shape is distorted octahedral a small dipole would be expected.

yes SF6 gas is used in modern ckt. breaker.
A vacuum circuit breaker has the circuit interrupting contacts inside a vacuum bottle. Without air the arc created by interrupting the circuit contains only material from the contacts. As a result the arc cannot sustain itself as well as it would if in air and the contacts will be able to handle higher currents. In an SF6 breaker the arc occurs in SF6 gas. SF6 captures free electrons from the arc quickly quenching it. In the process SF6 is broken apart but will recombine back into SF6. Some "SF6" breakers use vacuum bottles. This results in the small size of SF6 Switchgear with the advantages of vacuum breakers.

The volume is 13,64 L.
