Furnace Transformers
Synergy Transformers Pvt. Ltd. is a well-known and successful Furnace Transformers manufacturer in Rajkot, Gujarat, India. We are a team of engineers with expertise in the electrical field.
What Is a Furnace Transformer?
Any furnace that uses voltage other than standard commercial power needs a transformer. Whether for home or industrial furnaces, the transformer changes the voltage of the input power to a different voltage for use within the furnace.
How It Works
The input to the transformer connects to commercial power and goes through the primary winding–a coil of wires wrapped around a metal core. The primary induces a voltage into a secondary coil, usually with fewer windings, to reduce the voltage.

Features Of Furnace Transformers:
- Electrostatic earth shield provided between primary and secondary side windings for protection of rectifier elements against voltage surges in primary side windings. (Ref. D-2)
- Use reduced current densities to limit losses due to harmonic currents.
- Use reduced flux density to limit core losses due to harmonic flux.
- Designed to suit 6 Pulse / 12 Pulse or other rectifier circuits as required by furnace manufacturer. Two active parts in one tank can also be provided.
- Confirming to I.S. 2026 and I.S. 4540 – specifications for power transformer and specifications for rectifiers.
