Cylinder Gas Sf6 High Purity 99.999% Use in the Electric Power Industry
SF6 Common Applications
Electrical uses include high voltage circuit breakers, high voltage transformers, distribution voltage
switchgear, gas insulated power substations, gas insulated transmission lines, radar equipment, linear
particle accelerators and generators.
Approximately 80% of the annual consumption of SF6 is used for gas insulated substation (GlS)
equipment and medium voltage switchgear including circuit breakers and load break switches. Of the
80%, medium voltage switchgear accounts for approximately 10%. In both electrical applications,
the equipment is designed to contain the gas in sealed pressure systems which are assembled, filled
and tested in a controlled environment.

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.
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.
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.
