Sulfur Hexafluoride transformers Maintenance Unit price

Sulfur hexafluoride - Wikipedia hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an excellent 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.Chemical formula: SF₆

Transformer Efficiency, Losses and Heat, Losses and Heat. An ideal transformer would have no losses, and would therefore be 100% efficient. In practice energy is dissipated due both to the resistance of the windings (known as load loss), and to magnetic effects primarily attributable to the core (known as iron loss).
