Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made 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.Chemical formula: SF₆Molar mass: 146.06 g/molMelting point: −64 °C; −83 °F; 209 KSolubility in water: 0.003% (25 °C)high-voltage switchgears Gas-insulated switchgear Reclaim wika

Get Price"By adding the SF6-free 8DJH 12 model to our portfolio, we are continuing the story of blue GIS medium-voltage switchgear. The switchgear meets the requirements of tomorrow while providing all the familiar 8DJH functionalities, such as the proven operating concept for load-break switchgear, the same compact dimensions, and climate neutrality.People also askWhat is the problem with a SF6 breaker?What is the problem with a SF6 breaker?A SF6 circuit breaker may suffer from gas leakage problem. Because of that the pressure of the gas inside the extinguisher chamber decreases. The arc quenching capability of the breaker may deteriorates if pressure of the gas decreases. So to avoid this, regular checking of a SF6 CB, for SF6 leakage is quite necessary.Maintenance of SF6 Circuit Breaker - About Circuit
