Engineering Features
Built to Specification
Every unit is engineered to your duty cycle, environment, and target standards — no off-the-shelf compromises.
Where Special Transformers Excel.
Hazardous Areas — Oil, Gas & Petrochemical
Refineries, offshore platforms, gas processing — ATEX/IECEx Zone 1 & 2 certified Oil & Gas variants up to 40 MVA, 72 kV.
Industrial DC Processes
Electrolysis, smelting, plating, ESP for cement & power plants — Rectifier and ESP transformer variants engineered for continuous DC duty.
Grid Balancing & Power Flow Control
Phase-shift transformers for transmission interconnections, multi-tap units for variable load profiles, earthing transformers for ungrounded systems.
Drive & Auxiliary Systems
VSD drive transformers for motors and pumps, station-service auxiliaries for power plants and substations — engineered for harmonic-rich operating profiles.
