Types and Construction of Power and Distribution Transformers· Dry-type transformers operate in air or gas rather than being liquid filled. Just like with liquid transformers, the air or gas serves as an insulating medium and also to dissipate heat from the windings. The two general types of construction are the open or ventilated dry-type transformer and the sealed or closed-tank type.
