Powertech Transformers & Controls Pvt Ltd are the best in class Dry-type transformer manufacturers in India. In cast resin dry-type transformers, the complete encapsulation of primary and secondary winding in epoxy resin prevents penetration of moisture into windings. Dry-type transformers are used for small and medium voltage applications and are ideal for utility, commercial, and industrial applications. The cast resin transformers simplify the installation procedure as they do not require cooling oil. They are ideal for use in commercial areas. However, they are preferred for outdoor applications due to the greater noise generated than the oil type transformers.
Dry-type transformers offer good protection against adverse conditions and can also function without interruption at 100% humidity. Due to the high-grade insulation material, coils are non-hygroscopic & the transformer can be switched on directly even after a long period of service interruption. Cast resin transformers are efficient, economical, and have greater safety features than conventional oil transformers, as the oil transformers are a fire hazard due to the flammable oil used for cooling. For procuring the best quality transformers, consider Powertech Transformers & Controls Pvt Ltd, the leading Dry-type transformer manufacturers in India.
