A power transformer is characterized by inner and outer low voltage winding sections and a high voltage winding section disposed there between. The low voltage windings are comprised of a plurality of pancake coils, and the high voltage winding are comprised of a plurality of conductor strands spirally wound for a plurality of coil layers. The low and high voltage winding sections are laterally spaced with the low voltage windings disposed in side-by-side positions and adjacent to the high voltage windings. The high voltage windings have a smaller turn height than the low voltage windings and have conductor strands of smaller gauge than the pancake coils of the low voltage windings.

A Power transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. A varying current in the transformer's primary winding creates a varying magnetic flux in the core and a varying magnetic field impinging on the secondary winding. This varying magnetic field at the secondary induces a varying electromotive force (EMF) or voltage in the secondary winding. Making use of Faraday's Law in conjunction with high magnetic permeability core properties, transformers can thus be designed to efficiently change AC voltages from one voltage level to another within power networks.

Product Details:
Minimum Order Quantity1 Unit
Country of OriginMade in India
Output Voltage433v
Cooling TypeDry Type/Air Cooled
BrandTejaswini
Input Voltage33 or 11kv
Energy Efficiency LevelEEL-1,2,and 3
PhaseThree Phase

Distribution transformers for industrial application is available with primary voltages of up to 33 KV and secondary voltages ranging from 433 to 11000 V. The capacity range is up to 5000 KVA. We manufacture single phase distribution transformers, three phase distribution transformers and industrial distribution transformers.
These single phase distribution transformers and three phase distribution transformers are available with 'Tap Changer' options as well as "Off Circuit Manually Operated" and "On Load Tap Changer" (OLTC) with AVR and RTCC panel.
Copper foil winding technology is used for high current sections to achieve following advantages:
Sustaining short circuit forces without any distortion in low voltage and high current winding
Hot spot in LV windings regulated
No transposition, stray losses are minimal. Thus total copper losses are also further reduced
Total copper losses reduced vis-a-vis standard losses. Thus heat dissipating area also reduce
