We are a trusted Dry Type Transformer Wholesaler in Delhi, Sagarpur and Dry Type Transformer Manufacturer in Delhi, Sagarpur. We manufacture Cast-Resin Dry Type Transformers up to 3000 KVA, 33KV class as per Indian and International Standards (IS, IEC & ANSI). Our transformers are designed to withstand high humidity, temperature, adverse service conditions, and short-circuit levels, making them an ideal choice. Careful designing, selection of raw materials, state-of-the-art casting plant, in-house testing facility, and highly experienced manpower ensure our products are reliable, efficient, and cost-competitive.
Maintenance Free
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.Non- Hygroscopic
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.Non Inflammable and Self Extinguishing
Due to high quality insulation material the transformer is practically non-inflammable by an electrical arc, special fire protection measures are not required.Resistant against Temperature Fluctuation
The insulation material used is glass fibre reinforced with epoxy resin of class 'F' which can withstand wide temperature variation.Higher Impulse Strength
Contrary to the conventional dry type transformers the cast coil transformers are better in respect of impulse voltage withstand strength.Higher Short Circuit Strength
Higher dynamic short circuit withstand strength as compared to oil immersed and conventional dry type transformers because of fibre glass reinforced epoxy encapsulation.Free of Partial Discharges
No partial discharges can occur during operation.Instant Switching
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.No Leakage or Pilferage of Oil
As cast resin transformers are solidly cast, problem associated with oil filled transformers like oil leakage and pilferage of oil is completely avoided.Saving in Space
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.Eco-Friendly
Since no oil is used in these transformers, there are no chances of contamination of ground water due to oil leakage.Saving in Civil work cost and LT cables
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.
