Hitachi - Wikipedia was founded in 1910 by electrical engineer Namihei Odaira in Ibaraki Prefecture. The company's first product was Japan's first 4-kilowatt (5 hp) induction motor, initially developed for use in copper mining. [citation needed]The company began as an in-house venture of Fusanosuke Kuhara's mining company in Hitachi, Ibaraki.Odaira moved headquarters to Tokyo in 1918.Founded: 1910; 110 years ago, Hitachi, Ibaraki, Japan
Siemens supplies SF6-free high-voltage switchgear for ... supplies SF6-free high-voltage switchgear for English wind farm. Siemens will supply 102 SF 6-free, gas-insulated 8VM1 high-voltage switchgear (GIS) to Siemens Gamesa by the middle of next year.The switchgear will protect each wind turbine individually against overloads and short-circuits and make it possible to supply electricity reliably and without interruption.
SF6 Gas Servicing Equipment – ENERVAC INTERNATIONAL ULC Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution substations.
End-of-life factors in high voltage gas insulated ...· A first indicator for end-of-life of non-SF6 gases and gas mixtures would be the gas lifetime statement of the equipment manufacturer. A gas quality check (if possible) might indicate that the equipment can be used longer, or that the gas has to be replaced if its end-of-life condition is reached.

A bit of history on circuit breaker standards - Siemens USA number of these issues of the TechTopics series have discussed changes in the ANSI/IEEE standards for switchgear that have occurred in recent years. One of the more controversial changes was the revision of the circuit breaker standards to reflect the new "constant KA" rating method, replacing the older "constant MVA" ratings basis.
News Room : GE Grid Solutions key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: " The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.
Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
