hexafluoride Insulated Equipment for powergrid

Sulfur Hexafluoride INSULATED SWITCHGEAR for railway. Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas.
