Engineered to withstand extreme ambient temperatures (up to 55°C), heavy dust ingress, and frequent grid fluctuations. Certified to IEC 60076, IS 2026, and IS 1180 international quality standards.
Rebuilding and expanding Iraq’s electrical infrastructure—ranging from the high-load industrial hubs in Basra and Zubair to urban transmission grids in Baghdad, Mosul, and Erbil—requires strict adherence to rigorous engineering parameters. Substation equipment deployed across the region must maintain thermal stability under continuous heavy load cycles while mitigating the destructive effects of ambient sandstorms (Shamal winds), fine particulate ingress, and frequent voltage unbalance inherent to recovering utility networks.
As a specialized global manufacturer and established substation equipment supplier for Iraq, our engineering division delivers custom-designed power transformers, distribution step-down units, cast resin dry-type isolation systems, and compact secondary substations (CSS). Engineered in strict accordance with IEC 60076, IS 2026, and IS 1180 energy efficiency benchmarks, our equipment provides turnkey power distribution reliability for oil & gas fields, public utility discoms, industrial manufacturing plants, and commercial infrastructure developments across Iraq.
Why engineering consultants, EPC contractors, and procurement executives specify our substation transformer range for critical projects throughout the Middle East.
Unlike conventional round copper wire windings that experience severe axial mechanical stress during short-circuit faults, our high-voltage and distribution transformers utilize continuous copper/aluminum sheet foil windings. This eliminates transposition joints, ensures uniform mechanical distribution of radial short-circuit forces, reduces hot-spot thermal gradients, and significantly prolongs transformer service life under fluctuating grid conditions.
Ambient temperatures in southern Iraqi desert regions regularly exceed 50°C to 55°C. To prevent winding insulation degradation and oil breakdown, our engineering team recalculates top-oil temperature rise limits and winding temperature rise limits according to IEC 60076 specifications. We incorporate enlarged radiator banks, corrugated tanks, and dual-speed ONAF forced-air cooling systems engineered with C5-M anti-corrosion exterior coatings.
Our magnetic cores are built utilizing cold-rolled grain-oriented (CRGO) silicon steel imported from top-tier global mills. Featuring step-lap miter-cut joints and automated stacking, our cores deliver ultra-low no-load losses (NLL), minimal excitation currents, and reduced acoustic noise levels, complying with stringent energy efficiency norms (IS 1180 Level 1 & Level 2 / IEC Tier 2 requirements).
Providing specialized electrical infrastructure tailored to the operational demands of Iraq's unique economic sectors and geographic environments.
Upstream crude extraction and refinery processing plants require heavy-duty 33kV/11kV power step-down transformers and explosion-proof compact substations. Our units feature hermetically sealed oil tanks, double-gasketed terminal boxes, nitrogen cushions, and elevated surge arresters to protect heavy pump motors against harsh ambient gas atmospheres and severe voltage surges.
To support high-density residential and commercial expansions in major urban centers, municipal utility networks deploy our 11kV/0.4kV and 13.2kV cast resin dry-type distribution transformers. Possessing F1 fire-behavior and E2 environmental resistance ratings, these units provide zero fire hazard and low-maintenance distribution inside indoor underground substations and high-rise structures.
Heavy industrial manufacturing facilities—including induction melting steel foundries, cement grinding plants, and ceramic clusters—require custom furnace step-down transformers and isolation transformers. Engineered with reinforced mechanical clamping and K-factor harmonic mitigation, these transformers withstand repetitive high-current thermal shock and harmonic distortion.
As Iraq accelerates solar PV integration to supplement utility power, our inverter-duty multi-winding step-up transformers (2500kVA to 4500kVA) serve as the bridge between solar inverter outputs and 33kV transmission lines. Designed with electrostatic shielding between windings, these units eliminate high-frequency switching noise and harmonic feedback into the national grid.
The electrical power landscape in Iraq is undergoing a major structural transformation driven by the Ministry of Electricity (MOE), international development funds, and private-sector industrial investments. Key procurement and market trends shaping substation equipment supply include:

Detailed technical answers addressing local grid specifications, thermal design, shipping logistics, and quality assurance.
Standard transformers designed under standard IEC conditions assume an average maximum ambient temperature of 40°C. For equipment bound for Iraq, our engineering team re-rates the transformer design. We increase the radiator cooling surface area, utilize higher temperature class insulation materials (Class F or Class H resin for dry-type; high-flashpoint mineral or synthetic ester oil for liquid units), and lower the design temperature rise limits (e.g., limiting top oil temperature rise to 45°C instead of 60°C). This thermal margin ensures full rated MVA output without thermal trip or insulation lifetime degradation.
Every transformer dispatched from our facility undergoes comprehensive routine testing in accordance with IEC 60076. Each shipment includes guaranteed technical particulars (GTP), approved General Arrangement (GA) dimensional drawings, schematics, and official routine test certificates covering: Winding Resistance, Voltage Ratio and Vector Group Verification, Insulation Resistance, Separate-Source Voltage Withstand, Induced Overvoltage Withstand, No-Load Loss & Current Measurements, and Load Loss & Impedance Tests. Complete type test and short-circuit test reports from accredited independent laboratories are also provided upon request.
We provide heavy-duty seaworthy packaging engineered for long-distance maritime and overland transit. Liquid-filled power transformers are shipped either oil-filled or sealed with a positive nitrogen gas pressure cushion to prevent internal moisture ingress during ocean transit to Umm Qasr Port, Iraq. Bushings, conservator tanks, and delicate protection relays are disassembled, vacuum-packed in moisture-proof barrier foil, and secured in reinforced steel-banded wooden crates suitable for heavy crane handling and desert transport truck routes.
Yes. We welcome witness testing by client engineering representatives or appointed international inspection agencies (such as SGS, Bureau Veritas, Intertek, or TÜV) at our modern Rajkot manufacturing facility prior to dispatch clearance. We issue testing schedules in advance and provide full access to our calibrated routine test bays, impulse test equipment, and oil dielectric testing laboratory.
For outdoor oil-immersed substations, cable boxes and control cabinets are built with high-grade synthetic gaskets providing IP55 or IP65 ingress protection. For dry-type transformers, we supply heavy-gauge sheet steel IP23 or IP54 protective enclosures equipped with sand-trap louvered filters, anti-condensation heaters, and dual-layer powder coating treated against fine dust abrasion and atmospheric corrosion.
Fluctuating grids often experience unexpected external short-circuits and sudden load surges. Conventional wire-wound coils contain multiple wire crossovers that concentrate mechanical stress and hot spots, leading to turn-to-turn insulation breakdown. Continuous copper/aluminum foil winding eliminates axial mechanical forces, spreads dielectric stress uniformly, and improves heat transfer across the entire coil surface, extending transformer life under harsh grid conditions.
