Urja Techniques (India) Pvt. Ltd. manufactures and exports heavy-duty electrical transformers and substations compliant with international power utility specifications. With 30+ years of domain expertise, our transformers undergo rigorous ERDA & CPRI type testing to ensure high short-circuit withstand capacity, low acoustic noise, minimal harmonic losses, and exceptional dielectric strength.
We serve international EPC contractors, state electricity utilities, mining complexes, steel mills, solar plants, and heavy industrial facilities across more than 40 countries worldwide.
Complete indoor and outdoor package substations engineered for reliable power distribution networks, rapid site assembly, and long-term environmental durability under severe operational conditions.
Energy-efficient, low-loss oil-filled distribution transformers designed to regulate voltage fluctuations and reduce power grid losses across urban, rural, and industrial electrification projects.
Neutral Earthing Transformers designed to provide a neutral ground reference for ungrounded electrical systems, effectively controlling single line-to-ground fault currents and unbalanced load demands.
High-voltage power transformers up to 33kV and 66kV ratings. Built with high-grade electrolytic copper windings and cold-rolled grain-oriented (CRGO) steel cores for maximum efficiency.
Fire-safe, self-extinguishing vacuum pressure impregnated (VPI) and cast resin dry-type transformers (CRT) engineered for high-rise buildings, data centres, hospitals, subways, and chemical plants.
Heavy-duty multi-winding converter duty transformers designed to withstand complex harmonic distortion and thermal stresses caused by thyristor and VFD drive systems in industrial processes.
Rugged arc furnace and submerged arc furnace transformers optimized for extreme mechanical stress, frequent short-circuit currents, and heavy current output required in steel and smelting facilities.
Integrated modular compact substations combining HT switchgear, distribution transformer, and LT distribution panel inside a weatherproof enclosure for space-constrained urban environments.
