Indoor & outdoor substations, an overview· Properties of SF6: The SF6 gas is colourless, odourless and non-toxic. SF6 is an electronegative gas, which means that it has a high affinity for electrons. Whenever the electron collides with the neutral gas molecule, it is absorbed to form a negative ion, the movement of which is much slower than the free electron.
Point Group Of Sf6 standard grade SF6 is the most preferred form of sulfur hexafluoride in the power generation sector. With its pistol grip comfort and point-and-shoot convenience, even the tough spots become easy to diagnose. 2 Nodal patterns of the irreducible representations of the Oh group.
