Meiden develops groundbreaking high-voltage switchgear

The latter uses insulating gas gas only for the insulation. Sulfr hexafluoride gas has a greenhouse effect 23,900 times that of carbon dioxide. The reduced use of Sulfr hexafluoride gas with a VCB can help contribute to the prevention of global warming. In addition, gaz sf6 decomposes into a harmful gas when the electrodes open and close in a GCB, and needs to be disposed of in accordance with the law. In a VCB, in contrast, insulating gas does not turn into a harmful gas and is recycleable. 3. Reducing life-cycle costsGet price
