Kalpa Offers a Wide variety of Reactors, sometimes also known and Inductors or Chokes, for multiple applications are manufactured at Kalpa. A few among them are Filter Reactor, Detuned reactors, Series Reactor, Input/output Reactors. All the products are made as per Indian or International Standards (IS, IEC) or as per Customer requirements/ Application. All the manufacturing, testing and evaluation facilities are available in house

Our Range of reactors Include

• Detuned reactors
• Series Reactor
• Input/output Reactor

At Kalpa Electrikal Pvt Ltd, casting method of these transformers is obtained with the combined action of vacuum and temperature. The casting method makes it possible to assure void-free epoxy penetration of both the inner layer and between turn insulation. These Transformers are specifically needed in the distribution network for feeding basements or stilts of high-rise buildings, hotels, Malls, stadi-um, airports, chemical & refinery plants.

Assured Features

• Windings are electrically balanced to minimize axial short circuit forces.
• Coils are held rigidly in place between insulators clamped to the upper and lower core frames under highcompression.
• Precise casting under vacuum ensuring low partial discharge.
• Smooth surface finish and robust construction of MV & LVcastCoils.
• Adequate ducts between coils, discs for maximum airowand reducedhotspotTemperature.
• Step-lap designed CRGO laminations for lower losses and excitationcurrent.
