Cast Resin Transformer

Description

Type of Dry Type Transformer

The dry type transformer is of two types. They are

Cast Resin Dry Type Transformer (CRT)

Vacuum pressure Impregnated Transformer (VPI)

1.Cast Resin Dry Type Transformer (CRT)
Cast resin dry type transformer (CRT) is used in the high moisture prone areas. It is because of its primary and secondary windings are encapsulated with epoxy resin. This encapsulation helps to prevent moisture to penetrate to affect the winding material. Complete protection is achieved by this cast resin encapsulation so that the transformer can work without disruption in highly moisture prone area. Thus this transformer is non hygroscopic. This type of transformer is available in ratings of 25 KVA to 12,500 KVA. with insulation class of F (90oC Temp. Rise).
