7. Sulfur hexafluoride is an inorganic,
colorless, odorless, non-toxic and
non-flammable gas (under standard
conditions). has an octahedral
geometry, consisting of six fluorine
atoms attached to a central sulfur
atom. It is a hypervalentmolecule. ...

12. Advantages of SF6-Gas
Extremely high reliability in switchgear
To be used universally in power transmission
Power distribution (e. g. converters,
circuit breakers, transformers)
Avoids a fire hazard
MANAGMENT TRAINEE MODULE 12

13. Disadvantages of SF6
For some GIS types, no visible boundary (within gas zone)
Users not able to physically remove the bus selector disconnections (some
GIS types)
Construction issues and licensed unlicensed interaction not addressed
Liability and access issues regarding the gas zone
