Understanding Dry Type Transformers
Dry type transformers are essential components in electrical distribution systems, particularly valued for their safety and environmental benefits. Unlike oil-filled transformers, dry type transformers utilize air as a cooling medium, eliminating the risk of oil spills and reducing environmental hazards. This characteristic makes them ideal for indoor installations, such as in commercial buildings and industrial facilities.
