  • Meiden develops groundbreaking high-voltage

    A GCB uses sulfur hexafluoride (SF6) gas for circuit breaking, while a VCB is a switch that functions in vacuum. The latter uses SF6 gas only for the insulation. SF6 gas has a greenhouse effect 23,900 times that of carbon dioxide. The reduced use of SF6 gas with a VCB can help contribute to the prevention of global warming.
