GEESYS offers a full range of dry-type transformers with primary voltages through 72.5 kV built according to all major standards including IEC and ANSI. To minimize environmental contamination and fire hazard, customers are specifying dry-type transformers more frequently. These transformers meet strict parameters with respect to electrical system demands and functioning in areas with extreme climatic conditions. GEESYS's dry and cast transformers are virtually maintenance free and are manufactured in accordance with industry and international standards including ISO 9001.

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.

We have different types of dry type transformers as follows,

  • Oil Filled Transformers
  • Cast Resin Transformers
  • Unitised Sub-Station
  • Induction Furnace Transformers
  • Lighting Transformers

Low voltage transformers are manufactured in vacuum impregnation or in vacuum pressure impregnation (VPI) technology, depending on the application. These transformers are used in many standard and special applications, in commercial buildings, on board of vessels as well as in deep mines and industrial environments. Transformers with higher power rating are usually protected in appropriate enclosures sometimes equipped with air-forced, water-forced (AFWF). In the power range applications include galvanic separation or voltage adaptation.

All products are in accordance with industry and international standards and comply with GEESYS quality requirements.

Manufacturing Process Core

Three limb core construction is used. Core sheets conforming to drawings are made from Cold Rolled Grain Oriented (CRGO) Silicon Steel sheets. Individual sheets come duly coated with inorganic insulation. Circular Core cross section is used which is obtained by assembling number of steps of different widths. Number of steps and step widths are optimized to gain maximum advantage. Mitred joints are used between the limb plates & yoke plates. Fibre -glass tape banding hold the core tight and reduce the noise level. Treatment given to the completed core, protects it from atmospheric corrosion.


Both the H.V. and L.V. windings are made from copper conductors. Round wire, rectangular strip or foil is used depending on current to be carried. Layer type or cross over type winding is used depending on current / voltage to be handled. Windings are cast under vacuum.

On the H.V. side, inserts are provided to receive tap changing links. Inter connections between H.V. phases are obtained by links made out of copper tubes with their ends formed into lugs. These links are insulated by means of heat shrinkable tubes.


Protection against Overload/high winding temperature can be provided by Thermistors. ALARM and TRIP are provided, when required, by means of Thermistor or RTD sensors can be provided with 2 set point.


The cast resin dry type transformers are designed and tested to comply with national & international standards such as IS 11171, IEC 60726, ANSI, NEMA, and Australian Standard.
