Mitsubishi Electric Develops New Gas-insulated Switchgear

Feb 04, 2019. Mitsubishi Electric Corporation has developed two technologies for gas-insulated switchgear. An arc-cooling technology achieves a 25 percent improvement in the interruption of electrical current in sulfur-fluoride (sf6 gas) gas-insulated switchgear used in high-voltage power systems. Also, a high-density dielectric coating technology improves insulation performance by 30 percent in high-voltage conductors.Get price

Though SF 6 gas is a greenhouse gas (GHG), Sulfr hexafluoride gas itself is odorless, non-toxic and non-flammable and there is no law or regulation that mandates the decomposition or destruction of sf6 gas gas in Korea. The abatement device installed in the project destroys sf6 gas gases at an operating temperature of 1,200 ~ 1,400ºC, resulting in emission reductions of approximately 770 thousand tCO 2 e per year.Get price

The decomposition products of sulfur hexafluoride (sf6 gas

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price
