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 ...[email protected]

Best Air Insulated Switchgear(AIS) Manufacturer in China ... is an easy maintenance inflatable switchgear. The filling gas in the gas insulated switchgear is SF6 and N2 normally, so the maintenance cost is much higher than AIS. Also, when transporting, bumping is difficult to avoid. If a solid object on the switchgear has cracks due to bumps, the gas will leak and it is difficult to detect.
Gas insulated power transformers: A growing technology ... insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings. Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons.
