Product engineering standardized for all kV class

Engineering design common for all products under all kV Class, assured quality and reliability...

Design Philosophy OIP insulated outdoor products are subjected to extreme climatic conditions and hence extra care is taken in the design and process of such transformers. Major design trust of these products are therefore aimed at on the following five areas.

True Hermetic Sealing : We ensure that each unit is truly hermetically sealed so that it retain the insulation properties even after several years.
Reliability: Reliability is ensured at every design aspects and each process the product undergoes. Our entire range of products are highly standardized in its engineering design which is one of the key elements in ensuring high reliability.
Our products are truly maintenance free. Only periodical cleaning of insulators are required to be done.
We also give equal importance to the user-friendliness right from unpacking to the erection.
Safety come first. Even in the event of an unfortunate failure of the product, the products does not shatter or blast. We call our product is shatter-proof. In the event of any internal failure, the bellow acts as pressure relief device which peels off from the tank and thereby avoid any explosion.

Design HighlightsThink tank - Low Eddy Current Heating even at higher currents.
Thin Tank - Resilience effect - Absorbs mechanical shocks on primary terminals
Lumped Primary Winding with rectangular copper strips -Highest strength duringSTC
Specially designed rectangular copper lugs for primary winding termination - Strong and reliable joints
Capacitively graded Insulation - Uniform voltage distribution and partial discharge free performance Crimped joints on secondary leads Cemented flanges on insulator- uniform stress distribution.
True hermetic sealing - life long factory fresh insulation properties.

Process HighlightsMajor insulation is dried as per proven cycles under controlled vacuum and temperature
The EHV grade transformer oil is degassed and filtered until the desired properties are met (BDV > 75 kV )
Each unit is pneumatically pressure tested at lkg/cm2 (gauge ) at various assembly stages in order to assure the effectiveness of sealing points
Oil is filled from the bottom side under controlled vacuum and temperature and at an established steady & slow rate.
After oil flooding, each unit is hydraulically pressurized at lkg/cm2 (gauge }for 6 hours to check effectiveness of sealing.
Extreme care is taken to assure adherence to the painting process especially by assuring adequacy of time gap between each coat. There is no handling of the job after the final coat of the paint is
