We are offering dry transformers - vpi. 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. dupont nomex insulating material is used to secure the windings in place during vacuum and pressure impregnation process with superior class of resin to suit highly humid / dusty atmosphere & free from fire hazard. The result is a coil that exhibits high short circuit protection due to the tightly bond conductors comparable to completely resin encased molded transformers at a substantially reduced cost. dry transformers are very compact in sizes and hence suitable for basement installations in high rise buildings etc. Dry transformers are available with low losses giving savings over long service periods. Periodical vacuum cleaning of winding surface is the only maintenance. The capacity range of these iron core transformer is up to 2000 kva with primary voltage up to 11 kv class & secondary voltage between 433 to 6600 volts. we offer wide range of dry type transformers, dry transformers, dry type distribution transformers, dry distribution transformers, dry type electrical transformers, iron core dry type transformer, industrial dry type transformers, industrial iron core dry type transformer, dry type transformer, iron core dry type transformers, iron core dry type transformer, compact dry type transformers.
cast resin dry transformer

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 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. 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.
