Gas Density. Sulphur hexafluoride (SF6) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc quenching) properties. It thus makes it possible to set up complex and safe ­power distribution systems even in large cities. The insulation strength depends basically on the gas density.

Switchgear can be a simple open air isolator switch or can be insulated in another substance such as oil, pressurised sulphur hexafluoride gas, or insulated in a vacuum. Lower voltage switchgear can be enclosed within a building, however, higher voltages (approximately over 66 kV) usually require the switchgear to be externally mounted and insulated by air.
