Steps up & Steps down transformers

1.Core:

The core is made from best-grade imported cold-rolled grain-oriented silicon steel lamination. Lamination is cut at an angle of 45 degrees Celsius. Interleaved & mitered joints reduce the core losses & magnetizing current. A core is clamped with a steel channel rigidly to reduce the cartilage sound level.

2. Winding:

Windings are designed to optimize dynamic, thermal Mechanical & Electrical strives to depend upon the current & voltage requirement. The coils are wound with an electrolytic grade high conductivity annealed wire & stripe covered with high-quality insulation. Colling ducts are provided between windings & oil to minimize hot spot temperature & temp. gradient.

3. Insulation Oil:

Insulation material like a pre-compressed board, bakelite, tube, insulating top, varnish, epoxy/porcelains bushing, etc are used of the best quality to ensure a long life of transformers.
Oil is used as a coolant conforms IS 335 is centrifuged & filtered before filling into the transformer to ensure free from dust & moisture.

4. Tanks & Radiator:

All tanks are assembled by cold/hot rolled steel plates through welding. They are equipped with radiator corrugated steel sheets in accordance with capacity.

5. Paint:

Interior & Exterior surface is cleaned by chemical & coated with red oxide & 2 final coat of paint outside of tank body is coated for better & long life.

6. Temperature Rise:

Designed for maximum temp rise at full rated load, 40-50 degree Celsius for Aluminum wound & 45-55 degree Celsius for copper wound transform.
