GAS INSULATED TRANSFORMER
SF6 GAS INSULATED TRANSFORMER
EMPLOYS SF6 GAS INSTEAD OF THE CONVENTIONAL OIL BOTH AS AN INSULATING AND COOLING AGENT
SF6 – AN OVERVIEW
 SF6 is Sulphur hexafluoride formed by chemical reaction of molten sulphur and fluorine.
 It is colourless, odourless, nonflammable, non-corrosive and chemically stable.
 High dielectric strength.
 Quenches arc effectively and has excellent cooling properties.
 Good thermal conductivity and excellent thermal stability.
 It’s not poisonous and eco-friendly.
 It can be recycled.
APPLICATIONS OF SF6 GAS INSULATED TRANSFORMER
 Hospitals, underground shopping centers, substations where a high level of fire safety is required.
 Water treatment plants and hydroelectric power plants where waterways must be kept unpolluted.
 Thermal power plants, chemical plants, public works facilities etc where high reliability is required.
