The Distribution Transformer is a workhorse of medium-voltage distribution networks, stepping down voltage from MV (10–35kV) to LV (400/230V) for end-user supply. Available in both oil-immersed (sealed type) and amorphous-metal core low-loss variants, it is optimized for high efficiency, low noise, and economical operation over a decades-long service life.
Features include a step-lap core for reduced no-load loss and noise, copper or aluminum windings, off-circuit tap changer (±2×2.5%), and an expansion system suited to sealed or conservator design. Compact dimensions and standardized accessories simplify stocking and field replacement for utilities.
Tested per IEC 60076, GB/T 6451, and IS 2026. Widely deployed in rural electrification, urban grid reinforcement, industrial distribution, and renewable collection networks.
