A dry-type transformer is a type of transformer that never utilizes any insulating liquid with liquid immersion and winding. The windings and core are kept within a sealed tank with air pressure.

The cast resin dry-type transformer is utilized in high moisture-prone areas. It is led by encapsulated usage of the primary and secondary resins with winding material. The cast resin encapsulation provides complete protection to the transformer to ensure that it functions without disruption in a highly moisture-prone area. 

Therefore, this transformer is non-hygroscopic. It is a transformer made available in ratings of 25 KVA to 12,500 KVA with an insulation class of 90 C Temp. 

Featured Advantages of this type of transformer: 
•    They offer better overload capacity
•    They provide low partial discharge with low loss and hence provide good                    efficiency.
•    It is non-inflammable winding insulation that offers zero risk to fire hazards. That        is why it suits indoor installation. 

 Vacuum Pressure Impregnated Transformer (VPI) 
The winding insulation is void-free impregnation developed with class H polyester resin. The primary and secondary core winding is laced safely within a vacuum protective box. The moisture ingress protection does not let it get affected by the moisture. 

This transformer ranges from 5KVA to 30MVA with insulation grade H (180oC) and F(155oC).

Cast Coil Transformer 
Cast coil transformers are consistent in extreme weather conditions, and hence they require very less maintenance. They can also resist high short circuits. That is why they were used at an earlier time when liquid-filled units were available for harsh temperatures. Presently, these are massively used in tunnels, ships, cranes, nuclear plants, and mining industries. 

Dry Type Transformer Application
The major players operating in the industry are; Siemens AG, Schneider Electric, General Electric, Tbea Transformer Industrial Group, Hammond Power Solutions, and Voltamp Transformers. 
Therefore, the higher efficiency of dry-type transformers leads to their increased adoption.
