25 kVA Single Phase Distribution Transformer

High-performance 25 KVA Single Phase Distribution Transformer built for reliable and efficient power distribution.

25 kVA Three Phase Distribution Transformer — Shri Ram Transformer
How it works

Stepping high voltage down to usable power

The 25 kVA Three Phase Distribution Transformer efficiently converts high-voltage electricity into a stable three-phase low-voltage supply, ensuring safe, reliable, and energy-efficient power distribution for industrial, commercial, and utility applications.

HV INPUT → CORE & WINDINGS → LV OUTPUT
High voltage (input) Winding / core Low voltage (output)

Using premium CRGO core technology and precision-engineered windings, the transformer transfers electrical energy efficiently while maintaining complete isolation between high and low voltage circuits.
