SH Power provides full-lifecycle support for its transformers, encompassing solution design, model optimization, and on-site commissioning—all delivered by our highly experienced technical team. We offer tailored solutions for a wide range of applications to ensure efficient operation and maximize energy savings.
Single-phase overhead transformers with a rated capacity of 5–250 kVA and a frequency of 60 Hz are designed for pole-mounted overhead installation. Characterized by a small low-voltage (LV) power supply radius and low LV line losses, they are widely evaluated and deployed in urban and rural power grids. The products have been rigorously tested in strict accordance with the latest applicable standards, such as ANSI, NEMA, and ANSI C57.12.20. Our company can provide valid test reports.
