Dry Type Transformers

Dry Type Transformers

Unlike their liquid-filled counterparts, dry-type transformers do not incorporate liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils within a dry-type transformer are constructed of a gaseous or dry insulation medium.

A dry-type transformer is defined as a transformer that uses air or gas-instead of liquid-as the insulating and cooling medium for its windings and core, all contained within a pressurized, sealed tank.

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

Advantages of Dry Transformers
  • Dry-type transformers enhance safety by eliminating flammable or toxic liquids, reducing the risk of leaks or fires. They are maintenance-free and pollution-free because they do not require oil changes, oil tests, oil spill cleanup, or special disposal methods. These transformers are easy to install, as they do not require vaults or special foundations and can be placed close to the load, reducing the need for long and costly low-voltage cables.
  • Environmentally friendly, they do not emit harmful gases or contribute to the greenhouse effect. Additionally, these transformers handle overloads exceptionally well due to superior heat dissipation and thermal endurance compared to oil-filled types. They also reduce costs on civil installation works and fire protection systems, as they do not need oil containment pits, fire walls, fire extinguishers, or sprinklers.
  • Dry-type transformers perform excellently during seismic events, thanks to their rigid structure that withstands vibrations and shocks. They pose no fire hazard, as they have self-extinguishing properties and do not produce smoke or flames in the event of a fault. Furthermore, they exhibit excellent resistance to short-circuit currents due to their low impedance and high mechanical strength.
