Cast Resin Dry Type Transformers

Zero oil, fire-retardant dry type transformers designed for safe indoor installation in high-rise commercial complexes, hospitals, and subway stations.

Fire Safe & Clean

Dry Type Transformer Overview

Indian Power Trans Cast Resin Dry Type (CRDT) & Vacuum Resin Impregnated (VPI) transformers eliminate the need for flammable insulating transformer oil.

Encapsulated in epoxy resin under vacuum, these coils feature exceptional dielectric strength, self-extinguishing flame resistance, and maintenance-free operation inside ventilated IP23 or IP31 enclosures.

Key Benefits

F1 class fire behavior - non-flammable and self-extinguishing
Zero oil leakage risk - ideal for environmentally sensitive locations
Class F / H thermal rating with forced air (AF) cooling options
