Send an InquiryAs Serbia advances its National Energy and Climate Plan (NECP) and modernizes its distribution network under the stewardship of Elektroprivreda Srbije (EPS), the demand for high-reliability, low-loss overhead line equipment has reached an unprecedented peak. Pole-mounted transformers serve as the critical backbone of medium-to-low voltage (10kV, 20kV, and 35kV down to 0.4kV) step-down electrification across Serbia's agricultural zones in Vojvodina, industrial clusters in Kragujevac and Niš, and mountainous terrains in Šumadija and Zlatibor.
As an established ISO 9001:2015 certified transformer manufacturer and exporter, Chetan Electric Pvt. Ltd. delivers custom-engineered overhead pole-mounted transformers and dry-type cast resin units specifically tailored to meet European Committee for Electrotechnical Standardization (CENELEC EN 60076) standards and the European Union EcoDesign Directive (Tier 2 EU No 548/2014 & 2019/1783 no-load and load loss requirements). Our manufacturing footprint combines 30+ years of electromagnetic design expertise with CPRI (Central Power Research Institute) type-tested short-circuit thermal withstand guarantees.
The table below provides a comprehensive engineering benchmark comparing oil-immersed pole transformers, cast-resin dry-type units, and specialized industrial furnace/rectifier transformers manufactured for Serbian energy importers and B2B buyers.
| Transformer Type | Voltage Rating (kV) | Capacity Range (kVA) | Loss Compliance | Dielectric Insulation | Ideal Serbia Application |
|---|---|---|---|---|---|
| Single-Phase Oil Pole Unit | 10kV / 20kV / 35kV | 10 kVA – 167 kVA | EU 2019/1783 Tier 2 | Mineral Oil / Synthetic Ester | Rural overhead lines, agricultural pumping in Vojvodina |
| Three-Phase Hermetically Sealed | 10kV / 20kV | 50 kVA – 2500 kVA | EN 60076-1 / EN 60076-2 | ONAN Oil Cooled (CPRI Tested) | Urban step-down sub-stations, Belgrade industrial parks |
| Epoxy Cast Resin Dry-Type | 11kV / 20kV | 100 kVA – 3150 kVA | F1 / E2 / C2 Fire-Safe Class | Vacuum Cast Epoxy Resin (3:1) | High-density residential buildings, indoor mining shafts |
| PU Solid Encapsulated Pole Unit | 10kV / 20kV | 25 kVA – 500 kVA | High Moisture Shock Tolerant | Solid Polyurethane Elastomer | Sub-zero Balkan mountain passes, high seismic regions |

Optimized with Cold Rolled Grain Oriented (CRGO) prime silicon steel step-lap core stacking, significantly reducing no-load core losses (Po) and load losses (Pk) to exceed EU Directive 2019/1783 energy standards.
Deep hot-dip galvanized tanks combined with electrostatic polyurethane/furan resin powder coating. Tested for 1500+ hours under salt spray exposure to withstand harsh continental climate shifts.
Rigid internal axial and radial clamping system using thermally upgraded Kraft paper and high-density pressboard insulation, verified by CPRI short-circuit mechanical stress certification.
Serbia represents the central industrial and logistical nexus of the Western Balkans. Our CE certified pole-mounted transformers and advanced cast resin distribution products are designed to address the specific grid challenges encountered across Serbia’s regional geography:
The flat, fertile plains of Northern Serbia (Subotica, Sombor, Zrenjanin) demand continuous seasonal power for large-scale grain silos, automated irrigation pumps, and cold storage facilities. Our single-phase and three-phase pole transformers (ranging from 25 kVA to 160 kVA, 20kV/0.4kV) feature high surge impulse withstand capabilities to protect equipment against localized seasonal lightning strikes and long rural feeder voltage sags.
In the mining and smelting basins of Bor and Majdanpek, equipment is subjected to heavy particulate pollution, acid rain vapors, and extreme load harmonics. Chetan Electric supplies heavy-duty furan resin coated pole transformers and furnace units built with high-viscosity epoxy resin bushings, preventing tracking discharge and dielectric flashovers in heavily contaminated industrial environments.
Rapid urban expansion in Greater Belgrade (Novi Beograd, Eagle Hills waterfront developments) and Novi Sad requires fire-safe compact distribution nodes. Our vacuum cast resin (VPI) dry-type transformers eliminate transformer oil leakage risks, providing self-extinguishing Class F1 fire performance for pole platforms attached directly to mixed-use commercial buildings.
For small hydropower plants (SHPP) and solar microgrids across the Dinaric Alps and Stara Planina regions, temperature fluctuations can drop to -25°C in winter. Our hermetically sealed ONAN transformers utilize synthetic ester or refined mineral oil with pour points below -45°C, ensuring reliable cold-start performance and seamless bidirection power feed back into the national grid.
Essential technical insights for procurement engineers, EPC contractors, and electrical distributors in Serbia importing pole transformers from India.
Founded in 1994, Chetan Electric Pvt. Ltd. has grown into a premier international transformer manufacturing company with over 30 years of continuous innovation in electromagnetic engineering. Headquartered in Bangalore, India—a global hub for heavy electrical engineering—our facility boasts over 600 satisfied corporate and utility clients spanning real estate conglomerates, state power utilities, defense establishments (ISRO, BEL, BEML), and heavy process industries.
Every transformer design is type-tested at the renowned Central Power Research Institute (CPRI). All routine tests—including winding resistance, voltage ratio, phase displacement, short-circuit impedance, separate-source AC withstand voltage, and induced overvoltage tests—are performed in-house on 100% of production units prior to export.
In addition to traditional oil-cooled units, our facility specializes in state-of-the-art cast resin insulation. Utilizing low-viscosity 3:1 deep-casting epoxy resins, 1:1 polyurethane fast-cure polymers, and furan anti-corrosion coatings, our dry-type pole units offer superior moisture, fire, and chemical resistance.
We do not force rigid off-the-shelf constraints. Our experienced electrical engineering design team custom-configures kVA capacity, primary/secondary voltage ratios, vector groups (Dyn11, Dyn5, Yyn0), loss parameters, tank dimension constraints, and mounting bracket geometry to perfectly fit your existing pole platforms.
