High Purity 99.999% Sulfur Hexafluoride for SF6 Gas Insulated Substation
Description:
SF6 popularity is mainly due to its unique physical and electrical
properties including:
1) Dielectric strength twice that of air.
2) Nontoxic, nonflammable and noncorrosive.
3) Chemically stable with high breakdown strength. SF6 molecules provide excellent arc extinction
during electrical operations which minimizes contact wear and maintenance.
4) Excellent thermal conductivity. High heat transfer permits lower operating temperatures.
5) Readily available in many commercial locations.

|
Dielectric medium |
SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
|
Medical use
|
SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble.SF6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein.
|
Tracer compound |
Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing.
