A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (SF6) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation optical power from the two NIR lasers. A dual-channel high-Q photoacoustic cell (PAC) was[email protected]

Whether for medium voltage switchgear, high voltage switchgear or gas-insulated lines (GIL) our products always meet your requirements. The our company seal principle prevents the loss of SF 6 gas and moisture from penetrating the SF 6 gas system. our company couplings eliminate the loss of SF 6 gas by incorrect gas handling.
3-037-R001. Moisture is the most important criteria for the determination of the gas quality. This device has been designed specially for SF 6 moisture measurements. It shows a higher resistance against contamination and SF 6 decomposition products than conventional moisture sensors and even minimises the usual long time drifting.
19/03/2011Sulfur Hexafluoride is a colorless, odorless, nontoxic, inorganic, nonflammable gas. At Earth's atmospheric pressures, Sulfur Hexafluoride gas converts directly from a solid state to a gaseous one. SF6 looks like a liquefied compressed gas when its vapor pressure is (21.5 bar) units of pressure at 21.3&C and above.

Sulfur hexafluoride or sulphur hexafluoride is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6
