Power Transformers

Utility-Grade Power Transformers Engineered for Global Reliability

EUROGULF Transformers manufactures high-performance, custom-engineered power transformers ranging up to 132kV class at our state-of-the-art 100,000 sq ft facility in Hamriyah Free Zone, Sharjah, UAE. Designed to serve critical infrastructure within power generation plants, transmission substations, and sub-transmission electrical networks, our units guarantee seamless, continuous electricity delivery under harsh ambient temperatures and extreme operational environments.

Our engineering team utilizes advanced electromagnetic and thermal simulation software, combined with 3D Finite Element Analysis (FEA) modeling, to optimize core-and-coil configurations. This ensures extreme withstand capabilities against short-circuit forces, minimal electrical losses, low noise emissions, and extended equipment operational life exceeding 30+ years.

Key Engineering Specifications & Design Options

Each power transformer manufactured by EUROGULF is tailored strictly to international standards, regional grid codes, and specific client project tenders. Our units integrate premium raw materials sourced exclusively from Tier-1 global vendors, including high-permeability grain-oriented silicon steel cores and high-purity electrolytic copper windings.

Precision Manufacturing & Core-Winding Assembly

Our purpose-built plant operates under strict ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 quality and health-safety management systems. Electrical assembly takes place in environmentally controlled clean rooms to prevent moisture absorption and particulate contamination during critical manufacturing stages:

• Core Construction: Precision multi-step step-lap mitred lamination stacking minimizes no-load losses and magnetizing current.
• Winding Technology: Continuously Transposed Conductors (CTC) and high-grade insulating pressboard ensure uniform dielectric strength and heat dissipation.
• Vapour-Phase Drying & Oil Processing: Complete thermal-vacuum processing guarantees ultra-low moisture content inside the insulating cellulose insulation system prior to fluid filling.
• Corrosion-Resistant Enclosures: Tanks are shot-blasted and coated with heavy-duty multi-layer C5-M industrial marine-grade paint systems to resist coastal and desert weathering.

Independent Type Testing & Quality Control Verification

To provide absolute peace of mind for international procurement officers and utility engineers, EUROGULF power transformer ratings have undergone extensive short-circuit, temperature rise, and lightning impulse type tests at world-renowned independent laboratories, including KEMA (Netherlands) and CESI (Italy).
