Dry type transformers are commonly selected for indoor electrical rooms, commercial buildings, hospitals, schools, subways and other locations where clean operation and fire safety are important.

Outdoor and Industrial Distribution

Oil immersed transformers are widely used for outdoor distribution, industrial plants, utility systems and applications requiring stable heat dissipation under long operating cycles.
