Dry Type & Cast Resin Transformers: Safe, Reliable & Perfect for Indoor Power Applications

What Are Dry Type & Cast Resin Transformers?
Modern electrical infrastructure demands safe, compact, and low-maintenance power solutions. Dry Type & Cast Resin Transformers eliminate oil insulation, making them fire-resistant, eco-friendly, and ideal for indoor installations. While dry type transformers cool through air circulation, cast resin transformers encapsulate windings in epoxy resin to protect against dust, moisture, humidity, and pollution.
Key Importance
- ✔ Oil-free insulation for fire safety
- ✔ Air-cooled or resin-encapsulated windings
- ✔ Indoor-friendly compact installation
- ✔ Low noise & vibration operation
- ✔ High thermal & short-circuit withstand
