✅ What Is a Cast Resin Transformer?

A Cast Resin Transformer is a type of dry-type transformer in which the windings are encapsulated in epoxy resin through a vacuum casting process. This encapsulation protects the windings from moisture, dust, and chemical contamination, enabling installation in high-humidity, polluted, or fire-sensitive areas without special fire safety precautions.

✅ What Is a Dry Type Cast Resin Distribution Transformer?

Dry-type cast resin distribution transformers are used to step down medium voltage (e.g., 13.8 kV) to low voltage (e.g., 480Y/277V) for safe distribution to end-user loads. These transformers eliminate the use of oil, providing enhanced fire safety and simplified maintenance. They are especially suitable for use in hospitals, airports, commercial buildings, tunnels, metro stations, and renewable energy plants.
