Sulfur hexafluoride circuit breaker - Wikipedia

The first patents on the use of SF 6 as an interrupting medium were filed in Germany in 1938 by Vitaly Grosse and independently later in the United States in July 1951 by H. J. Lingal, T. E. Browne and A. P. Strom (Westinghouse). The first industrial application of SF 6 for current interruption dates to 1953. High-voltage 15 kV to 161 kV load switches were developed with a breaking capacity of 600 A.Get price

sf 6 recovery - DILO

Although SF 6 is an excellent insulating and quenching medium it is very important to know that. SF 6 is a fluorinated gas (F gas) with the highest global warming potential. It is one of the six gases subject to monitoring under the Kyoto protocol. Relating to the greenhouse effect, 1 kg of SF 6 corresponds to a GWP value of more than 22,800 times higher than that of CO 2.Get price
