Dry-type transformers Protect against fire and leakage
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 helps in hindering moisture to enter to impact the winding material. Complete security is achieved by this cast resin encapsulation so the transformer can operate without break in deep moisture inclined zone. Accordingly, this transformer is non-hygroscopic. This type of transformer is available in ratings of 25 KVA to 12,500 KVA, with an insulation class of F (90 degrees C Temperature Rise). This type of transformer has some featured advantages benefits. Can be fitted outside in...
