Service - SF6 – FAQ - WIKA Benelux#!The quality of the SF 6 gas must be analysed, since it can lead to chemical reactions in the gas when used in gas-insulated switchgear, due to the high energy occurring there. An analysis of the SF 6 gas quality is always recommended and should be an integral part of the maintenance strategy, especially before any gas handling.[email protected]

Switchgear - Wikipedia 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.
