DOT 48.8L Cylinder Packed Sf6 Replacement Gas Used In High Voltage Transmission Lines And Mutual Inductors
At room temperature and pressure, Sulfur hexafluoride is a colorless, odorless and non-toxic gas. Not burning. Thermally stable, chemically inert. In the red hot state above 500 ℃ does not break down, below 800 ℃ is very stable. At 250 ℃ with sodium metal reaction. Not corrosive, you can use common materials, do not corrode the glass. Electric insulation performance and arc extinguishing performance, the insulation performance of 2 to 3 times the air, and the greater the gas pressure, the higher the insulation properties. Pharmacology is not active, no poison. Slightly soluble in water, dissolved in alcohol and ether more than in water. Insoluble in hydrochloric acid and ammonia. Water solubility: 5.4cm3SF4 / kgH2O (SF6 partial pressure 101.325kPa, 25 ℃). Dielectric constant: 1002049 (gas, 101.325kPa, 25 ℃). S.P. at 21.1 ° C was 2308 kPa.

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.
