This 50kVA single-phase pole mounted transformer is professionally designed to convert 4.16kV high voltage to standard 120V low voltage for reliable overhead power distribution. Built with optimized magnetic circuit, precision winding structure and robust oil-immersed design, it delivers ultra-stable voltage output under fluctuating load conditions, avoiding voltage drops or surges that affect equipment operation.

Featuring high-quality materials, fully sealed construction and anti-aging insulation system, this unit achieves an exceptionally long service life with consistent performance over decades of outdoor use. Ideal for residential communities, small industrial loads, street lighting networks and rural power grids, it combines stable power delivery, long-term durability and low maintenance to provide a cost-effective, long-lasting solution for utility and commercial power distribution projects.

The transformer adopts precision-designed winding turns ratio and optimized magnetic circuit structure to ensure accurate voltage conversion from 4.16kV to 120V. With excellent load regulation performance, it maintains stable output voltage even under sudden load changes, effectively protecting connected electrical equipment. Built-in voltage regulation capability further enhances operational stability for long-term distribution applications.

The tank is manufactured from high-strength cold-rolled steel with anti-corrosion coating, providing excellent resistance to outdoor weather, UV radiation and moisture. Fully sealed with vacuum oil filling technology, it completely isolates air and moisture to prevent insulation oil oxidation and winding aging, greatly extending product service life. Integrated cooling fins ensure efficient heat dissipation for continuous full-load operation.

High-permeability cold-rolled oriented silicon steel is used with step-lapped lamination technology to reduce core loss and improve energy efficiency. Overall vacuum impregnation enhances mechanical strength, reduces noise and improves resistance to short-circuit impact, laying a solid foundation for stable performance and long service life.

High-conductivity copper windings ensure low resistance, high efficiency and strong overload capacity. Insulation materials are treated with vacuum pressure impregnation (VPI) to enhance dielectric strength, moisture resistance and aging resistance. High-creepage bushings ensure stable performance in harsh outdoor environments, further supporting long-term reliable operation.

Designed for standard utility pole mounting, it comes with complete installation fittings for fast and convenient installation without large-scale civil engineering. Compact structure saves space and reduces construction difficulty, suitable for various distribution network scenarios.

Custom voltages such as 120/240V split-phase are available to meet different project requirements.
