Making:
Core BuildingCRGO i.e. Colled Rolled Grain Oriented. Core of a transformer is similar to the heart to a living being. Considering the importance of coil, many issues are kept in mind while their designing, like manufacturing functional reliability, longer service life, economy etc.

Coil Winding
The Windings allow the flow of oil around the conductor in-between sections. These Windings are made of high grade electrolytic copper, which are designed to optimize thermal, mechanical and electrical stresses depending upon the current & voltage requirements.

Assembly
This plays a major role in several processes like space utilization, compactness, ease of transportability, handling & installation. Care is taken in every respect for judicious space utilization and that too without compromising with the functional efficiency.

Transformer Oil
Virginity & purity of oil used in transformers is of paramount importance. The contamination, inclusion of foreign particles, even of microscope level or water particles, causes harmful effects on proper functioning of the transformer.

Tank & Final AssemblyAfter ensuring that the active part is fully dry & moisture free, it is lowered inside a suitably designed & fabricated mild steel tank. These tanks are thoroughly cleaned & painted before testing and are filled in with freshly filtered oil.

Tank Fabrication & Sand Blasting
The corrosion due to presence of moisture in the environment, brittleness of material due to influence of various gases, the formation of rust flakes, etc is not desirable on the surface of the transformer tank. These will have adverse effects on surfaces & ultimately lead to shortening of service life.

Drying / Ovening
We take care for drying individual coil and insulation components to ensure that they match the duty cycle and short circuit forces, which the winding may encounter in service.

Ready to Dispatch
During final assembly all pipe work, bushings and radiators are fitted to the transformer.
