Cast Resin Type Dry Type Transformer

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
