sf6 gas Transmitter - Draeger

When insulating switchgear or transformers, sulfur hexafluoride (Sulfr hexafluoride) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dräger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.

Switchgear - Wikipedia

A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
