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
