15kVA Pole Mounted Transformer 4160V Compact Pole Mounted Current Transformer
This 15kVA single phase pole mounted transformer is purpose-designed for overhead power distribution systems, delivering stable voltage conversion for residential, rural, light commercial, and utility applications. Built with a highly compact design that minimizes size and weight while maintaining full performance, it is optimized for quick and easy installation on standard utility poles without requiring dedicated ground space or complex civil works.
Featuring a rugged oil-immersed structure, reliable voltage regulation, and strong overload capacity, this transformer ensures consistent power output for long-term distribution use. Its space-saving form factor, simplified mounting system, and robust build make it the ideal choice for grid upgrades, street lighting, rural electrification, and small-scale power supply projects where quick deployment and efficient space usage are essential.
The transformer uses a streamlined cylindrical tank constructed from high-strength cold-rolled steel, resulting in a significantly reduced footprint and lighter weight compared to conventional models. The compact profile allows flexible placement on narrow or limited pole locations while maintaining excellent structural rigidity and wind resistance for pole-mounted suspension. Fully sealed construction prevents moisture and dust ingress, supporting long service life in outdoor environments.
The core is manufactured from high-quality cold-rolled oriented silicon steel with a precision step-lapped lamination process to reduce core loss and improve energy efficiency. Vacuum impregnation treatment enhances mechanical stability, reduces operating noise, and ensures reliable performance under continuous load. This design supports stable voltage output and low energy consumption throughout operation.
Windings are made from high-conductivity copper material for low resistance, high efficiency, and strong short-circuit withstand capability. Insulation components are processed using vacuum pressure impregnation (VPI) to deliver excellent dielectric strength and resistance to lightning impulses. High-creepage bushings ensure stable performance in humid, coastal, and polluted environments.
Engineered for fast field deployment, the transformer comes with standard mounting brackets and hardware compatible with most utility poles. Wiring terminals are clearly arranged for convenient connection, and the lightweight compact design reduces lifting and handling difficulty. No special tools or large-scale construction are required, enabling rapid installation and power-on.
