POWER TRANSFORMERS/ GENERATOR TRANSFORMERS - OIL IMMERSED

PRODUCT FEATURES These Transformers are used in highly humid environment

Perfect for areas with limitation of maintenance service and confined space conditions

Excellent for compact substation units

Excellent for Highly Polluted Atmosphere

HERMETICALLY SEALED TRANSFORMERSIn Hermetically Sealed Transformers, the dielectric insulating fluid in the transformer tank is completely sealed and not connected to atmospheric air. This type of transformer is used in applications where the transformer is to be installed in harsh climatic conditions (moist, smoke, polluted, dusty environment, etc.) or where the user prefers a low maintenance transformer. The design avoids air in the transformer tank, thereby avoiding sludge formation and oxidation of the dielectric fluid.



These transformers can be installed wherever oil filled units cannot be used such as inside buildings, in tunnels, cranes, off shore platforms, ground catchment areas, public places etc.
