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.
FEATURES OF A GAS INSULATED TRANSFORMER
Highly flame resistant and non explosive.
High resistance to moisture.
Reduced installation space.
High reliability.
Causes no pollution.
Explosion proof tank.
Easy inspection and maintenance work.
