sulphur hexafluoride QUALITY for 132kv

Sulfur Hexafluoride (SF6) is an inorganic, colorless, odorless, and non-flammable gas. SF6 primary use is in the electrical industry as a gaseous dielectric medium for various voltage circuit breakers, switchgear and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
