Our cast resin dry-type transformers comply with national as well as international standards such as IS 11171, IEC 60076-11, BS, and CE. Also, we use enclosure of IP55 Degree of Protection rating. We manufacture cast resin dry-type transformers up to 3.5 MVA and 33 kV Class. These transformers are air-cooled. Cast resin dry-type transformers are used for indoor as well as outdoor applications. In these transformers, the complete encapsulation of primary and secondary winding in epoxy resin prevents penetration of moisture into windings. The cast resin offers very good protection against adverse ambient conditions. These transformers can work without disruption of service at 100% humidity. Due to the high-grade insulation material, coils are non-hygroscopic & the transformer can be switched on directly without pre-drying even after a long period of service interruption. Contrary to the conventional dry-type transformers the cast coil transformers are better in respect of impulse voltage withstand strength.
