A dry-type transformer is a type of transformer that never uses any insulating liquid where its winding or core is immersed in liquid. Rather the windings and core are kept inside a fixed tank that is pressurized with air.

Type of Dry Type Transformers

Dry-type transformers are of two types

1. Cast Resin Dry Type Transformer (CRT)

Cast resin dry type transformer (CRT) is used in high moisture zones. It is because of its primary and secondary windings are encased with epoxy resin. This encapsulation

The ever-growing derive towards smaller and lighter items presents many difficulties for the power supply architects. Specifically, discarding abundance heat created by power semiconductors is turns out to be increasingly troublesome. Subsequently it is significant that the power supply is as small and as proficient as possible, and throughout the years power supply engineers have responded to these difficulties by consistently decreasing the size and improving the productivity of their structur
