The Difference Between Dry-type Transformer And Oil-immersed Transformer Structure

Dry Type Transformer: The structure is relatively simple and the volume is small. It is mainly composed of iron core, winding, insulation material and shell. The winding is usually cast with epoxy resin or other polymer materials to form a solid insulator. Oil-immersed transformer: The structure is relatively complex. The iron core and winding are immersed in transformer oil. The shell is usually welded with steel plates and has strong protective performance.
