Energy Transformer — Manufacturer, Supplier, Wholesale & Custom OEM Factory

The 37.5 kVA Electric Pole Transformer is one of the most widely used single-phase distribution transformers in North America and South America, supporting residential, rural, agricultural, and light-commercial loads. As an essential component of the overhead power grid, this oil-filled pole-mounted transformer provides reliable voltage conversion from medium-voltage primary lines (such as 13.2 kV, 13.8 kV, 12.47 kV, 7.62 kV) to standard low-voltage outputs like 120/240 V.

Energy Transformer manufactures and supplies high-performance 37.5 kVA pole transformers engineered to meet ANSI, IEEE, DOE, CSA, and various South American utility standards. Our units are built for long service life, low maintenance, and stable operation in harsh climates including tropical, coastal, desert, high-altitude, and rural environments.

With factory-direct production, competitive pricing, and full customization options, Energy Transformer is the preferred supplier for utility companies, distributors, EPC contractors, and government electrification programs across the Americas.
