Designed to satisfy the stringent requirements of Romania's distribution system operators (DEER, Rețele Electrice, Delgaz Grid), delivering optimal thermal performance and short-circuit withstand capabilities.
Our ground-mounted distribution transformers are manufactured to meet European standard EN/IEC 60076 and the EU EcoDesign Directive Tier 2 requirements, ensuring minimal no-load losses and enhanced structural integrity.
Optimized magnetic cores manufactured with high-permeability grain-oriented silicon steel significantly reduce load and no-load losses to meet European energy conservation benchmarks.
Reinforced clamping structures and advanced coil winding technologies guarantee proven withstand capability during sudden three-phase dynamic short-circuit surges.
Designed for severe temperature fluctuations common in Romania, ranging from -30°C winter conditions in mountainous zones to +42°C in the Danubian plain with C5-M anti-corrosion protection.
Pre-configured integration ports for fiber-optic temperature sensors, pressure relief telemetry, and on-load tap changer (OLTC) controllers supporting modern automated substations.
Romania represents one of the most dynamic energy markets in South-Eastern Europe. Driven by the National Energy and Climate Plan (NECP) and substantial European modernization funds, the Romanian power network is undergoing comprehensive technological revamping. The transition involves substituting aging medium-voltage infrastructure with energy-efficient, robust ground-mounted distribution transformers compliant with EU Regulation 2019/1783.
Major distribution system operators including DEER (Distribuție Energie Electrică Romania), Rețele Electrice (covering Banat, Dobrogea, and Muntenia Sud), and Delgaz Grid are actively upgrading their 6kV, 10kV, 20kV, and 35kV networks to minimize transmission losses and enhance reliability for industrial consumers.
Replacing high-loss legacy units with high-efficiency S13-M and S22-M oil-immersed ground-mounted units.
Stepping up generated electricity from large-scale photovoltaic and wind parks in Dobrogea and Muntenia to 20kV/35kV grids.
From heavy industrial plants along the Prahova Valley to modern high-tech automotive hubs in Transylvania, ground-mounted distribution transformers form the bedrock of continuous electrical distribution.
Powering complex robotic lines and stamping presses in automotive manufacturing hubs across Mioveni (Argeș), Craiova (Dolj), Timișoara, and Brașov with superior overload capacity.
Delivering customized step-up ground-mounted pad-mounted substations and zigzag earthing units for solar projects across Oltenia and onshore wind corridors across the Dobrogea plateau.
Installed in tier-3 data facilities around Bucharest-Ilfov and logistics hubs bordering the A1 and A3 motorways, supplying clean, stable electrical energy with low acoustic emission profiles.
Serving petrochemical installations near Ploiești and Constanța, utilizing specialized rectifier transformers and explosion-proof transformer enclosures engineered for harsh chemical environments.
Factory calibrated to align with Romanian standard transmission requirements (Transelectrica) and local medium-voltage distribution systems.
