What are Dry Type Transformers?

A Dry Type Transformer is a type of electrical transformer that uses air instead of liquid for insulation and cooling. These transformers are safe, environmentally friendly, and require less maintenance.

Dry Type Cast Resin Transformers are a subtype of dry transformers where the windings are encapsulated in epoxy resin (non-hygroscopic).

This design protects against moisture, dust, and corrosive environments, making them ideal for harsh conditions like coastal areas, mines, and chemical plants. They are highly durable, fire-resistant, and efficient, with minimal environmental impact.
