Premium Series

Cast Resin
Transformers (CRT)

Cast Resin Dry-Type Transformers are designed for indoor environments with minimal fire risk and maximum operational safety. These are moisture-resistant, maintenance-free, and ideal for sensitive installations.

Key Highlights

Non-flammable and self-extinguishing insulation

Uses epoxy resin that resists ignition and extinguishes automatically, ensuring fire safety.

Resistant to dust, moisture, and chemicals

Ideal for harsh indoor environments like basements and high-rises with poor ventilation.

Minimal maintenance required

No oil or fluid handling needed; no risk of leakage or contamination.

Silent operation

Low noise emissions make it suitable for commercial and institutional buildings.

Compact and lightweight

Smaller footprint than oil-filled types, simplifying space planning in urban structures.

Safe for sensitive installations

Perfect for hospitals, airports, malls, and IT facilities due to enhanced safety and reliability.
