Single-phase overhead transformer

SH Power offers full life-cycle support for its transformers,covering solution design, model optimization, and on-site commissioning—all handled by our experienced technical team. We provide tailor-made solutions for various applications to ensure efficient operation and maximize energy savings.

Description

A single- phase overhead transformer with a rated capacity of 5~250kVA and a frequency of 60Hz, used in column overhead installation, has a small radius of low-voltage power supply, and low-voltage line loss is low. It is widely used in rural and urban power grids.The products have been tested in strict accordance with the latest versions of applicable standards such as ANSI, NEMA, and ANSI C57.12.20. Our company will provide valid test reports.
