  • Corrosion Protection: Epoxy-coated or hot-dip galvanized tanks for long-term outdoor use
  • Customizable Terminals: Cable box, bus duct, or bushing-mounted options
  • Optional Accessories: Conservator tank, breather, Buchholz relay, temperature gauge, MOG, WTI, OTI, etc.

🧪 Quality Assurance & Testing

All oil cooled distribution transformers from 25 kVA to over 2500 kVA undergo extensive in-house testing in line with IS 1180 / IS 2026 protocols:

  • Routine tests: IR, ratio, impedance, short circuit, and load loss
  • Special tests on request: Lightning impulse, temperature rise, noise level
  • Transformer oil: Tested for moisture, acidity, BDV, and sludge formation

We maintain a zero-defect policy, ensuring that every transformer delivered performs reliably and safely in the field.
