SF6 gas in medium-voltage switchgear | T&D Guardian ... early units experienced relatively high gas leakage. As the experience with SF6 in high-voltage circuit breakers grew, the manufacturers introduced "single-pressure" designs and improved sealing techniques, greatly reducing the leakage rate.
Environmental performance | National Grid ET emissions that are in our control, the biggest source is insulating gases. In 201 8 /1 9, emissions from SF6 were 2 85,247 tonnes of CO2, a 30% increase from 201 7 /18.. There was an increase in SF6 leakage in 2018/19 of 55,400 tCO2e (2318 kg of SF6). The number of new leaks decreased in comparison with 2017/18, however the magnitude of a small number of leaks grew.

Gas-insulated transmission lines: the next generation of ... insulated transmission lines (GIL) provide technical, environmental and operational features which make them a very good alternative wherever the transmission of extra high voltage (EHV) and extra high currents (EHC) is needed within restricted space, e.g. wherever overhead lines cannot be used.
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.
