SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Thus, it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas due to its properties. Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas.[email protected]

Siemens develops SF6-free gas-insulated medium-voltage switchgear. At this year's Hannover Messe, Siemens will present another medium-voltage switchgear that doesn't require sulfur hexafluoride (SF6) as the insulating gas: the 8DAB 12. The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas.

Deployment of the g3 gas mixture as a replacement for SF6 has taken a major step forward: the F35-145 kV gas-insulated substation (GIS) is now SF6-free too. It has the same physical footprint as its SF6-based GIS predecessor and can operate at ambient temperatures as low as -25 &C.
01/12/1997Unfolding and repositioning of Descemet's membrane by sodium hyaluronate (Healon) were followed by injection of sulfur hexafluoride 20% gas mixed with air to fill the anterior chamber. Initially, the gas bubble filled most of the anterior chamber; it disappeared over 7 to 9 days.

WG.B3.45. TB 802: Applications of Non-SF6 Gases or Mixtures in Medium and High Voltage Gas Insulated Switchgear. Despite its remarkable insulating and arc quenching characteristics, SF6 is a significant contributor to greenhouse gases and the industry is trying to minimise and better manage the use of this gas.
750kv-substation-onsite-service. On-site SF6 recovery service is driven by a trailer which equipped with our full set of recovery, refilling, purification equipment and measuring instrument, drive to the substandard gas compartment, perform onsite shutdown and maintenance, directly recover unqualified SF6 gas, recycle and purify them to be qualified and then return to gas compartment, the maintenance cycle is shorter, and users do not have to invest any money in purchasing SF6 gas handling
CALIBRATION GASES. Calibration Gases, also called reference gases and standard gases, belong to gaseous standard material. It is widely used in fields of chemistry, physics, biology and petrochemical engineering. Calibration gases consist of minimum two, and can be as high as 31 components which are based on customers requirements. The method of preparation of calibration gases is gravimetric

Sulfur hexafluoride - Wikipedia hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing. The gas is used in the final stage of ASHRAE 110 fume hood qualification. A plume of gas is generated inside of the fume hood and a battery of tests are performed while a gas analyst arranged outside of the hood samples for SF 6 to verify the containment properties
SF6 Transmitter - Draeger The SF6 transmitter is ideally suited for the gas measurement of sulfur hexafluoride in the field of high voltage engineering. The transmitter can be used both as a gas leak detector and to monitor the gas quality in gas-insulated switchgear (GIS) or transformers.
