High-Efficiency Overhead Power Distribution Transformers
Urja Techniques (India) Pvt. Ltd. designs, engineers, and exports top-tier Pole Mounted Transformers (single-phase and three-phase) optimized for reliable voltage stepping down in rural, urban, and industrial overhead distribution grids. Engineered with low-loss High-Grade Electrolytic Copper windings and prime-grade Cold Rolled Grain Oriented (CRGO) silicon steel cores, our transformers ensure superior efficiency, reduced operational losses, and exceptional lifespan.
Built to withstand extreme atmospheric conditions, ambient temperatures from -25°C to +50°C, and heavy electrical surges, each pole transformer features a corrosion-resistant steel tank, high-dielectric mineral oil (or eco-friendly ester fluids), and robust porcelain bushings to maximize power uptime for international electrical utilities, EPC contractors, and commercial projects.

Design & Structural Superiority
- Overhead Pole Mounting Brackets: Heavy-duty mounting lugs designed for easy installation on single or double pole structures.
- Robust Hermetic Seal: Sealed tank structure prevents moisture ingress, oxidation, and oil degradation over extended service life.
- Corrosion Weatherproofing: Shot-blasted steel tanks treated with polyurethane and epoxy paint systems to endure UV rays, coastal salt mist, and industrial environments.
- Enhanced Surge Withstand: High basic impulse level (BIL) insulating design safeguards against lightning and grid switching surges.
Operational Benefits for Buyers
- Energy Conservation & Low Losses: Exceeds global eco-design requirements to minimize no-load and load loss costs for power utilities.
- Zero Maintenance Design: Sealed oil system minimizes fluid degradation, reducing maintenance overhead and service intervals.
- High Short-Circuit Resistance: Rigid mechanical clamping of core and coil assemblies withstands severe grid fault stresses.
- Global Export Readiness: Tailored to fit diverse international grid voltage ratings and environmental parameters across Africa, Middle East, Europe, and Latin America.
