SF6 decomposition Network Monitor for Maintenance

Properties of SF6 (Sulfur Hexafuoride) GasHandling Nonfaulted SF6Handling Faulted SF6Disposal of Wastea) ToxicitySF6 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. The…b) Toxicity Of Arc ProductsToxic decomposition products are formed when SF6 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 n…c) Physical PropertiesSF6 is one of the heaviest known gases with a density about five times the density of air under similar conditions. SF6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that it is more compressible dynamically tha…See more on electrical-engineering-portalPublished: 2011-1-4Cheap Sf6 Detection System Honeywell On-site SF6 recovery service is driven by a trailer which equipped with our full set of recovery, refilling, purification equipment and measuring instrument, drive to the substandard gas compartment, perform onsite shutdown and maintenance, directly recover unqualified SF6 gas, recycle and
