2014/4/5The variation of pressure with temperature is linear for sulfur hexafluoride and it is small within the service temperature, i.e. from – 25 to + 50 o C. The volumetric specific heat of this gas is also high. It is around 3.7 times more than that of air, and that is why this gas also has a tremendous cooling effect in electrical equipment.

Changes in temperature, pressure, or oxidant concentration may cause the flammability range to vary considerably.InertGases that do not react with other materials at standard temperature and pressure are classified as inert. They are colorless, odorless, nonflammable, and nontoxic. The primary hazards of these gases are the high pressure and potential for asphyxiation. These gases are often stored at pressures exceeding 2,000 psi.

Synthesis and ReactionsApplicationsGreenhouse GasPhysiological Effects and PrecautionsSee AlsoFurther ReadingExternal LinksSulfur hexafluoride on Earth exists primarily as a man made industrial gas and has also been found to occur naturally. SF6 can be prepared from the elements through exposure of S8 to F2. This was also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any S2F10 (which is highly toxic) and then scrub…See more on en.wikipedia.orgMissing:container InstrumentMust include:container InstrumentSynthesis and reactionsApplicationsGreenhouse gasSee alsoReferencesPrefabricated Compact Substation, package substation … orecco/prefabricated compact substationPrefabricated Compact Substation The prefabricated compact substation is one kind of compact complete set of distribution equipment which designed combining medium voltage switchgear, low voltage switchgear, distribution transformer, energy metering devices and reactive power compensation devices into one or several boxes according to a certain wiring scheme.
