News Room : GE Grid Solutions

The key difference between g3 and sf6 gas is that g3 is a gas mixture while insulating gas is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.Get price

When loosening the coupling parts again, the same O-ring prevents gas loss whilst the self seal valves close.Get price

Industrial sf 6 Gas Pressure and Measurement Products - WIKA USA

Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. In addition, TD plant safety depends on the purity of SF 6 gas. Under normal conditions during an electrical discharge, the six fluorine atoms split from the sulfur atom to capture electrons; after quenchingGet price
