How Dry Type Transformers Work

Dry-type transformers operate on the principle of electromagnetic induction, using air or solid insulation (such as epoxy resin) instead of oil for cooling and insulation.

Key Components & Working Principle:

1.Core – Made of high-permeability silicon steel laminations to minimize energy loss.

2.Windings – High-voltage (HV) and low-voltage (LV) windings, made of copper or aluminum, enable voltage conversion via electromagnetic induction.

3.Insulation System – Epoxy resin or VPI (Vacuum Pressure Impregnation) technology ensures high dielectric strength and thermal stability.

4.Cooling System – Natural air cooling (AN) or forced air cooling (AF) ensures stable operation under load.

Since dry-type transformers do not use oil, they eliminate risks like oil leaks and fires, making them ideal for safety-critical applications.
