Top 10 Indoor Dry Type Transformer Suppliers in China 2026

Introduction to Indoor Dry Type Transformers

Indoor dry type transformers are an essential component in the power distribution system, especially for indoor applications. Unlike oil - immersed transformers, dry type transformers do not use flammable oil as an insulating medium. Instead, they rely on solid insulation materials such as epoxy resin, which makes them safer for indoor use, as there is no risk of oil leakage and fire.

These transformers are known for their high - reliability, low noise levels, and excellent environmental adaptability. They are widely used in various indoor settings, including commercial buildings, hospitals, schools, and industrial facilities, to step up or step down the voltage levels according to the specific power requirements of the electrical equipment.
