Distribution Transformers Built to BIS. Built to Last.
From 500 kVA to 2500 kVA, up to 33 kV — BIS-certified distribution transformers
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.
