Dry Type Transformers require minimum maintenance to provide many years of reliable trouble free service. Unlike liquid fill transformers which are cooled with oil or fire resistant liquid dielectric, Dry Type Transformer utilize only environmentally safe, CSA and UL recognized high temperature insulation systems. Dry Type Transformer provides a safe and reliable power source which does not require fire proof vaults, catch basins or the venting of toxic gasses. These important safety factors allow the installation of dry type transformers inside buildings close to the load, which improves overall system regulation and reduces costly secondary line losses. Our Dry Type Transformers are a rather mature product and technology but, of all the components in a power system, a transformer replacement can be a physically challenging event, extended delivery of a replacement or repair unit and expensive transportation costs. These are transformers whose core and coils are not immersed in insulating oil. Fire-resistant dry type or "cast resin" transformers are well suited for installation in high-rise buildings, hospitals, underground tunnels, school, steel factories, chemical plants and places where fire safety is a great concern. Hazard free to the environment, dry type transformers have over the years proven to be highly reliable. �Dry type� simply means it is cooled by normal air ventilation. The dry type transformer does not require a liquid such as oil or silicone or any other liquid to cool the electrical core and coils. Dry type transformers are voltage changing (Step-up or Step-down) or isolation device that is air cooled rather than liquid cooled. The transformer case is ventilated to allow air to flow and cool the coil (coils).

Dry type transformers are suitable for indoor installations in explosive atmospheric areas and populated locations such as malls, multiplex etc. These dry type transformers have F or H insulation class with or without enclosure as per the site requirement.

Drive Duty or Converter Duty Transformers are multi pulse & multi winding rectifier transformers. The number of Secondary windings can be 6, 9, 12, 15, 18 pulse or more for better harmonic cancellation. Product Feature Transformer with Multiple Secondary’s .Each Secondary has extended Delta that controls terminal voltage phase angle.

Dry type Power / dry type Transformers are used in locations where safety is of utmost priority and where conventional transformers with oil / paper composite dielectric can be a liability and prone to fire hazards. Dry type transformers are the preferred option in such situations. A Dry Type Transformer is similar to Conventional Oil immersed Transformers in design and manufacturing, both magneticallyand electrically. The key difference is in insulation and cooling method as well as the processing of the coils.   The Dry Type Transformers are designed and tested to comply with National & International Standards like IS : 11171 & IEC : 60726.   The company is capable of manufacturingtransformers to any other standards as per customers / consultants requirement.     Features Fire resistant and safe. Lower losses. Non-hygroscopic. Free from partial discharges. High dynamic short circuit strength. Good overload capacity. Hign impulse strength. Environment friendly. Low cost of installation and maintenance.

In cast-resin dry-type 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 hygroscopes & 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. Higher dynamic short circuit withstands strength as compared to oil immersed and conventional dry type transformers because of fibre glass reinforced epoxy encapsulation. No partial discharges can occur during operation. The insulation material used is glass fibre reinforced with epoxy resin of class 'F' which can withstand wide temperature variation. Due to high quality insulation material the transformer is practically non-inflammable by an electrical arc, special fire protection measures are not required.Due to encapsulation of coils with cast resin the coils dimensions are stable & no coil tightening is required to maintain the short circuit strength. Also no check of oil level and electrical insulation/oil is required. This leads to saving in cost on account of maintenance.As cast resin transformers are solidly cast, problem associated with oil filled transformers like oil leakage and pilferage of oil is completely avoided. These transformers are generally smaller in dimensions and lesser in weights. The construction and installation cost for the sub-station can be reduced by adopting dry type transformers.Without fire or danger of explosion, it is possible to place the transformers near to the load centre. Also, these transformers do not need construction of special fibre brick walls or oil pits, which reduces the overall civil works. Additionally, since LT cables are not required, thers is also saving in cost on account of expensive cable laying works.Since no oil is used in these transformers, there are no chances of contamination of ground water due to oil leakage.

We manufacture technically advanced range of dry type transformers. These chokes are manufactured using quality material such as copper wires terminal blocks, which allows a magnetic field to form around the coil when the current flows through. The materials used in the manufacturing of the dry type power transformers are of optimum quality that ensures high durability and resistivity to various corrosive conditions.
