Distribution Transformers Built to BIS. Built to Last
From 250 kVA to 2500 kVA, up to 33 kV — BIS-certified distribution transformers for urban grids, industrial estates, and infrastructure projects across India.
Product Overview
The Standard for Indian Grid Distribution.
KLR Distribution Transformers are manufactured in strict conformance with Bureau of Indian Standards (BIS) — making them procurement-ready for state utilities, DISCOMs, government infrastructure projects, and private industrial consumers across India.
Every unit is designed in-house using 3D SolidWorks, wound on automated machines in climate-controlled bays, and tested in our own laboratory before despatch. The result is a distribution transformer that performs reliably across India’s demanding ambient conditions — from coastal humidity to extreme inland heat.
