High-efficiency dry-type and oil-immersed power distribution transformers engineered in compliance with IEC 60076, CENELEC, and EPS technical specifications.
As Serbia advances its National Energy and Climate Plan (NECP) alongside the comprehensive modernization of Elektroprivreda Srbije (EPS), the demand for high-reliability, low-loss power transformers has reached unprecedented levels. The Republic of Serbia serves as the vital energy transit hub of the Western Balkans, connecting Central Europe to the Black Sea region. Achieving long-term grid stability across 110kV transmission networks, 35kV regional distribution nodes, and 10kV/0.4kV industrial step-down substations requires electrical equipment designed to withstand rigorous thermal stress, harmonic distortions, and severe environmental swings.
Strategic Advantage for Serbian Procurement Directors: Our direct China wholesale manufacturing model bridges technical compliance with unmatched price-to-performance metrics. Every power transformer shipped to Serbia complies strictly with European EcoDesign Tier 2 losses (EN 50588-1), IEC 60076 standards, and custom EPS sub-station dimensions, ensuring zero friction during customs clearance and commissioning.
With over 44 years of specialized transformer manufacturing experience under our group's engineering framework, we provide comprehensive OEM/ODM solutions. From high-permeability Cold-Rolled Grain-Oriented (CRGO) silicon steel core assembly to 99.99% pure oxygen-free copper windings, our transformers minimize total cost of ownership (TCO) while guaranteeing operational lifespans exceeding 30 years under continuous full-load conditions.
Engineered specifically for the geographical, climatic, and industrial demands of Serbian regional power projects.
Rapid urban developments, commercial centers, and high-density residential towers require low-noise, flame-retardant indoor power distribution. Our SCB10 / SCB13 Cast Resin Dry-Type Transformers (1000kVA–2500kVA) feature F1 fire resistance class, producing zero toxic gases and eliminating oil-leak hazards in underground vaults.
The vast solar PV arrays and wind farms in the Pannonian Basin demand transformers capable of handling reverse power flows, severe voltage fluctuations, and transient harmonics. Our S20 Series 35kV ONAN Step-Up Transformers provide optimized tap-changer dynamics and extreme short-circuit withstand capabilities.
Serbia's copper mining hubs and industrial heavy plants operate in highly aggressive outdoor environments filled with dust, sulfur, and heavy electrical surge loads. Our 66kV / 35kV Substation Step-Down Transformers incorporate C5-M anti-corrosion surface treatments, reinforced oil conservators, and double-winding insulation.
To meet the technical expectations of Serbian energy engineers and EPC contractors, our manufacturing infrastructure incorporates zero-compromise metallurgy and automated winding systems:
We utilize high-permeability, cold-rolled grain-oriented silicon steel sheets with 45-degree fully slitted miter joints. This advanced stacking technique drastically reduces magnetic leakage, resulting in up to 30% lower no-load current and significantly reduced audible noise levels.
Both high-voltage (HV) and low-voltage (LV) coils are manufactured using 99.99% high-purity electrolytic copper. Insulated with DuPont Nomex or high-density insulating paper, our windings demonstrate exceptional mechanical strength during peak short-circuit electrodynamic forces.
Our oil-immersed tanks undergo thorough vacuum drying and high-vacuum oil filling processes. This eliminates micro-bubble voids within the insulating liquid, elevating dielectric strength above 60kV breakdown voltage.

As Serbia continues its alignment with EU energy market frameworks, compliance with stringent environmental and electrical parameters is mandatory for all imported power assets:
Our distribution transformers are designed to meet Tier 2 max load and no-load loss limits mandated across Europe. This directly mitigates carbon emissions and lowers energy operational expenditures for Serbian distribution system operators (DSOs).
Serbia's topography experiences periodic seismic activity. All transformer tanks and structural frame supports undergo finite element stress analysis (FEA) to endure horizontal and vertical acceleration forces exceeding Grade 8 on the MSK seismic intensity scale.
Winter ambient temperatures in mountainous Serbian regions like Zlatibor or Kopaonik can drop below -25°C. Our transformers utilize high-grade synthetic or refined mineral oils with pour points down to -45°C, ensuring instant cold-start reliability.
Addressing technical, logistical, and customs inquiries regarding power transformer imports to Serbia.
Yes. Our engineering team customizes vector groups (e.g., Dyn11, Ynd11), short-circuit impedance percentages, and tap changer ranges to integrate seamlessly into EPS 10kV, 35kV, and 110kV substation grids.
We routinely arrange multimodal shipments via ocean freight to major European entry ports such as Rijeka (Croatia), Bar (Montenegro), or Piraeus (Greece), followed by heavy-load road transport directly to your job site in Belgrade, Niš, or Novi Sad.
Every export order includes complete factory acceptance test (FAT) reports, CE declarations of conformity, ISO 9001 certificates, EUR.1 / Certificate of Origin, commercial invoices, and detailed packing lists signed by certified quality auditors.
We back our power transformers with a standard 24-month full warranty (extendable up to 60 months). Spare parts, including Buchholz relays, temperature control indicators, and oil bushings, are dispatched via expedited air cargo when requested.
