SF6-alternative gases switch electrical equipment cart system

Aug 23, 2010This gas has certain electrical properties that make it suitable as an insulation and switching medium in switchgear for power distribution. SF6 breaks down into toxic substances on incineration. For example, when an internal arc occurs in the switchgear, SF6 gas and its toxic byproducts are released into the atmosphere.
