Many friends have the question about what types of dry type transformers are on the market. As a China transformer manufacturer who can supply high quality dry transformers, we are here to provide the answer.

1. Open type dry transformer, also called No-encapsulated dry type distribution transformer: It is a commonly used form. Its body is in direct contact with the atmosphere and is suitable for a relatively dry and clean room (when the ambient temperature is 20 degrees, the relative humidity should not exceed 85%). Generally, there is air self-cooling and air cooling two cooling methods.

2. Closed type transformer, also called encapsulated dry type distribution transformer: its device body is in a closed shell and does not directly contact the atmosphere (due to poor sealing and heat dissipation conditions, it is mainly used for mining and is an explosion-proof type).

3. Casting type, also called molded cast coil dry transformer or resin cast dry transformer: epoxy resin or other resin is used as the main insulation. It has a simple structure and small size, and is suitable for transformers with small capacity.

In China, most transformer manufacturers can supply resin cast dry type transformers, for this type of transformer are more popularly used in China or exported to other countries.
