The history of gas-insulated substations | Think Grid 6 gas was already known during the 1940s. Westinghouse holds the original patent for the use of SF 6 as interrupting medium, and their engineers developed the first applications for switches and circuit breakers in the early 1950s. In the 1960s all major manufacturers such as BBC-Calor Emag, Siemens, Magrini, Merlin-Gerin, NEI-Reyrolle, the Japanese and Delle-Alsthom had started intensive ...
