Excellent Electrical Insulator Sulfur Hexafluoride Gas Cylinder Storage Used For Breakers
SF6 gas-insulated electrical equipment has the following main features compared to oil-filled electrical equipment:
(1) is not easy to fire, high security. Normal temperature, atmospheric pressure under the SF6 is non-combustible gas, in case the equipment itself or the surrounding fire, SF6 will not burn, to prevent the spread of the fire. The enclosed parts of the enclosed combination are sealed in the metal shell of the ground, and there is no danger of electric shock, and there is no accident caused by external factors such as flying and can ensure safe operation.
(2) long service life and maintenance cycle. SF6 electrical equipment for the complete sealing structure, the external air, moisture and other impurities and other intrusive, generally do not appear inside the moisture and gas, dust pollution and other phenomena, and its parts are surrounded by inactive SF6, thus slowing the electrical Material aging. SF6 itself is not perishable, sediments and other contaminating impurities are less, compared with the oil-filled equipment, the relative extension of the equipment life and maintenance cycle.

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.
