A Dry Type Transformer is defined as a transformer that does not use any liquid as an insulating or cooling medium for its windings or core. Instead, the windings and core are enclosed in a sealed tank that is filled with air or gas under pressure.

Dry Type Transformers are widely used in various industries and applications because of their safety, reliability, and environmental benefits. They can operate in harsh conditions such as high humidity, fire risk, and seismic events without compromising their performance or posing any hazard to people or property.
