We do only manufacture of Dry Type Transformers with Class – C Insulation (Nomex Aramid Paper & Silicone Varnish) by Vacuum Pressure Impregnation Process (VPI).

Distribution & Power Transformer
Specification: Upto 3000 KVA, 22KV Class

A Power transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the dry transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field through the secondary winding.

Power Transformer
Lighting Transformer
Specification: From 50 KVA Onwards

lighting transformers are designed for industrial, commercial and outdoor applications where efficient control is required of tungsten and ballast loads as well as non-inductive loads.

Lighting Transformer
Non-Ventilated Weatherproof Transformer
Specification : Upto 750 KVA Rating

The core and coil assembly is mounted inside an enclosure which has no ventilation openings.

Non-Ventilated Weatherproof Transformer
Ventilated Rainproof Transformer
Specification:Upto 2500 KVA Ratings

Ventilated Enclosure allows air to flow directly over the core and coil assembly for cooling..

Ventilated Rainproof Transformer
Winding :
HV Coils are Sectional type with cross over windings where each section of coil is individually wrapped toroidally with 7 or 10 mil glass tapes. Inter-coil porcelain separators are secured on coil edges during the glass covering so that entire section of a coil obtains highest level mechanical and electrical strength after VPI Impregnation in the Silicone Varnish.

Transformers above 200 KVA Secondary Windings are made of Copper Foils with Nomex Paper Interlayer which are extremely rugged in construction and also capable of withstanding Short Circuit Current Situations as well as Voltage Surges more efficiently comparing to Multiple Strip conductors. This type of winding gives Lower Eddy Losses and Lower “Hottest Spot” Temperature which is better than conventional Multiple Strip Conductors wound coils.
