🌱 What is a Dry Type Transformer?
A dry type transformer is a magnetic core transformer where the windings and core are enclosed in a sealed tank using air as a cooling medium, instead of oil or other liquids typical in traditional transformers. Major technologies for manufacturing dry type transformers include cast resin and vacuum pressure impregnation (VPI).

- In cast resin dry type transformers, high-voltage and low-voltage windings are impregnated and encapsulated under vacuum with epoxy resin. This prevents moisture penetration and provides excellent fire protection, making them ideal for indoor installations such as underground and city-building substations.
- The VPI dry type transformers employ vacuum impregnation with polyester or epoxy, followed by baking under pressure cycles, ensuring high mechanical strength and performance under variable loads.
✅ Advantages of Dry Type Transformers
The dry type transformer market is expanding due to several distinct advantages:
- Easy installation and lower maintenance costs.
- High resistance to short circuit currents and capacity to handle overloads.
- Eco-friendly as they use no hydrocarbon liquids.
- Self-extinguishing properties that reduce the need for elaborate civil installation and fire protection systems.
These benefits have increased the adoption of dry type transformers in industrial, commercial, and residential applications. Industries use them for specific voltage requirements and safety against fire and chemical hazards.
