Standardized solutions engineered for 20kV Romanian regional distribution grids, 35kV renewable collection substations, and heavy industrial step-down installations.
Class F/H insulation, self-extinguishing epoxy, optimized for Romanian commercial complexes and indoor substations.
Heavy-duty capacity engineered for Dobrogea wind farms and Muntenia utility-scale photovoltaic collector systems.
Ultra-low no-load loss design tailored directly to Transelectrica and regional Romanian power distribution requirements.
Robust dynamic withstand capability with on-load tap changers for regional transmission nodes and industrial hubs.
Navigating the modernization of Romania's national transmission network (Transelectrica) and regional distribution operators (Electrica, Distribuție Oltenia, Rețele Electrice Dobrogea/Muntenia/Banat, Delgaz Grid).
Romania represents one of the most dynamic and fast-evolving electricity markets in Central and Eastern Europe. As part of its commitments under the European Union Green Deal and the National Energy and Climate Plan (PNIESC), Romania is undergoing a comprehensive transition toward modern, decarbonized, and intelligent power distribution networks. Key utility operators across regions such as Muntenia, Oltenia, Transylvania, Banat, and Moldavia are rapidly replacing aging legacy substations with modern cast resin dry-type transformers and high-efficiency oil-immersed units.
Cast resin transformers have emerged as the preferred technological choice for industrial and commercial projects across Romania. Unlike oil-immersed transformers, epoxy cast resin units completely eliminate dielectric fluid leaks, offer exceptional fire self-extinguishing capabilities (Class F1), generate zero toxic gases (Class F0/F1), and can operate securely in harsh environmental and condensation conditions (Class E2/E3, Climatic Class C2/C3/C4). These characteristics make them irreplaceable for metropolitan centers like Bucharest, Cluj-Napoca, Timișoara, Brașov, and Iași where fire safety regulations in densely populated areas, high-rise commercial facilities, and underground substations are strictly enforced by European safety codes.
The Dobrogea region boasts some of Europe's premier wind energy corridors, while southern and western Romania are experiencing a massive surge in utility-scale photovoltaic (PV) solar farms. Our 35kV and 20kV dry-type transformers provide exceptional transient surge withstand and low-loss inverter stepping to handle severe harmonic loads without thermal degradation.
Serving major manufacturing hubs in Pitești, Mioveni, Craiova, and Arad. From automotive assembly lines to metallurgical and chemical facilities, our cast resin solutions deliver non-stop operational security, eliminating downtime caused by insulation breakdown or fire containment protocols.
Bucharest and Cluj-Napoca are booming IT and hyperscale data center nodes in Eastern Europe. Our dry-type transformers feature extremely low noise emissions, compact footprint, IP21-IP31 protective enclosures, and intelligent PT100 temperature monitoring systems integrated into local SCADA.
Designed strictly in compliance with IEC 60076-11, EN 50588-1, and the European Union Ecodesign Directive (EU) No 548/2014 & 2019/1783.
Our transformers utilize top-tier Huntsman/Araldite epoxy resin systems infused with silica quartz filler, cast under high vacuum conditions. This sophisticated casting ensures void-free encapsulation of high-voltage windings, keeping partial discharge levels below 5 pC (picocoulombs)—well beyond typical European requirements. This virtually eliminates insulation aging and ensures maintenance-free operation over a 30+ year service life.
In Romania, continental climate extremes bring freezing winter temperatures dropping below -25°C in the Carpathian Mountain areas and hot summer peaks exceeding +38°C in the Wallachian Plain. Our cast resin formulation provides exceptional thermal elasticity, preventing micro-cracking during sudden cold starts or severe dynamic load swings.
