Industrial insulating gas 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
