gasbanor so2 Analysis in high electrical switchgear

The gas used most often in High Voltage Switchgear is sulfur hexafluoride (SF 6). This gas has relatively high dielectric strength, good thermal conductivity, is non-flammable and is chemically inert and nontoxic for humans and animals. After being dissociated by an electric arc, it recombines quickly and almost completely.
