Mitsubishi Electric’s commitment to progressive research, development and testing is evident through numerous technological advancements in the last century, including:
• The first gas insulated circuit breakers in 1965
• The world’s first 550kV GIS in 1976
• Testing of the first 1,100kV GIS in 1994
• Installing two 245kV, 80kA gas insulated substations in North America
Today, with the availability of high power, high voltage, climate control and vibration laboratories, Mitsubishi Electric GIS systems can be designed and tested to meet the demands of any application.
