EUROGULF Transformers delivers world-class factory repair, emergency site overhauling, and rating upgrades for power and distribution transformers up to 132kV class. Engineered for minimal downtime and maximal operational life extension.
Turnkey Transformer Maintenance & Overhauling Solutions
Industrial power transformers represent crucial capital assets in electrical infrastructure. While transformers are inherently low-maintenance compared to rotating machinery, aging insulation, thermal stresses, moisture ingress, and short-circuit forces require specialized refurbishment to prevent catastrophic failure.
Equipped with a 100,000 sq. ft. purpose-built manufacturing and service facility in Hamriyah Free Zone, Sharjah, UAE, EUROGULF Transformers provides utility-grade factory overhauling alongside rapid-response on-site repair capabilities. Our engineering team combines over 30 years of manufacturing expertise with state-of-the-art diagnostic and processing technology.
Core Repair & Refurbishment Capabilities
Whether handling scheduled preventative maintenance or emergency breakdown recovery, EUROGULF executes repair projects under strict international compliance standards including IEC 60076, IEEE C57, BS, and NEMA specifications.
1. Factory-Based Complete Overhaul & Rewinding
For severely degraded or failed transformers, factory overhauling offers a cost-effective alternative to complete replacement. Our facility handles active part extraction, core re-stacking, and high-precision coil rewinding using high-purity copper conductors and thermally upgraded insulation materials.
- High-voltage and low-voltage winding replacement (copper/aluminum conductors).
- Core restoration, lamination repacking, and core-clamp insulation testing.
- KEMA & CESI type-tested technology alignment for guaranteed electrical performance.
- Complete tank surface treatment, sandblasting, and anti-corrosion poly-urethane painting.
2. On-Site Emergency Repair & Field Refurbishment
To minimize transportation downtime for large power transformers, EUROGULF deploys specialized mobile field units equipped with high-vacuum oil processing rigs, precision testing equipment, and experienced site engineers.
- Gasket, seal, and bushing replacement on-site to eliminate oil leaks.
- On-Load Tap Changer (OLTC) contact overhaul, timing measurement, and mechanism servicing.
- Radiator bank replacement, valve servicing, and cooling system upgrades (ONAN to ONAF).
- On-line passive moisture extraction and continuous oil degassing setup.
Advanced Diagnostic Testing & Quality Assurance
Every repaired or overhauled transformer undergoes rigorous testing inside our electrically isolated High Voltage Test Laboratory before recommissioning. Diagnostic verification guarantees that repaired units meet original OEM insulation thresholds and power efficiency metrics.
- Dissolved Gas Analysis (DGA): Early detection of thermal faults, arcing, and paper degradation.
- Sweep Frequency Response Analysis (SFRA): Detecting winding mechanical displacement and core deformation.
- Dielectric Withstand & Impulse Testing: Confirming BIL withstand capability under transient surge conditions.
- Turns Ratio & Winding Resistance Measurement: Verifying magnetic circuit symmetry and tap changer continuity.
