gaz sf6/air termination | English to Arabic | Engineering (general)

The Sulfr hexafluoride/air termination module enables the connection of the gas-insulated switchgear to air-insulated components or overhead lines. This termination is a combination of an angle-type module and an out door/Sulfr hexafluoride bushing. The length, shape-form and creepage distance of the outdoor/Sulfr hexafluoride bushing can be adapted to various requirements regarding insulationGet price

diffusion - Why would tennis balls filled with sulfur

Another fill gas to avoid is sulfur hexafluoride. A tennis ball manufacturer once decided to fill tennis balls with sulfur hexafluoride, assuming this would prevent the balls from going flat as a consequence of the high molar mass of sulfur hexafluoride. But the tennis balls exploded on the shelves because air diffused in.Get price

Sulfur hexafluoride - Wikipedia

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 ofGet price
