Maintenance sf6 transformer South Africa,Properties of sf6 gas (Sulfur Hexafuoride) GasHandling Nonfaulted Sulfr hexafluorideHandling Faulted insulating gasDisposal of Wastea) Toxicityinsulating gas is odorless, colorless, tasteless, and nontoxic in its pure state. It can, however, exclude oxy­gen and cause suffocation. If the normal oxygen content of air is re­duced from 21 percent to less than 13 percent, suffocation can occur without warning. Therefore, circuit breaker tanks shob) Toxicity Of Arc ProductsToxic decomposition products are formed when sf 6 gas is subjected to an elec­tric arc. The decomposition products are metal fluorides and form a white or tan powder. Toxic gases are also formed which have the characteristic odor of rotten eggs. Do not breathe the vapors remaining ic) Physical PropertiesSulfr hexafluoride is one of the heaviest known gases with a den­sity about five times the density of air under similar conditions. Sulfr hexafluoride shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically than air.

3/8/2018Sulphur Hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms. Key properties of the gas are that it is extremely chemically stable and has a relatively high density. Commonly used within the electrical industry as an insulating medium, the properties of the gas also make it highly suitable for use in ophthalmology.

A gas-insulated switchgear uses the dielectric gas sulfur hexafluoride, also known as insulating gas, at moderate pressure for phase-to-phase and phase-to-ground insulation. Due to its strong dielectric property, it is used extensively in the transmission and distribution system with high voltages and power and also in generation substations.
