sf6 gas Grid Solutions for Ultra High Voltage

sf6 gas Grid Solutions for Ultra High Voltage

sf6-gas is a versatile gas used in various industries, such as magnesium and aluminium casting and insulated window glazing. But by far its most important application, and one that was first proposed by Vitaly Grosse of AEG (a GE Renewable Energy's Grid Solutions ancestor company), is in high voltage power transmission equipment.
