WINLEY supplies pole-mounted transformers that meet your high expectations, including both single-phase and three-phase. Single-phase transformers range from 15 kVA to 333 kVA, three-phase range from 15 kVA to 500 kVA. These transformers comply with ANSI, IEEE, CSA, IEC60076, and other international standards. 

Pole-mounted transformers are characterized by their compact size, strong overload capacity, high reliability for continuous operation, and simple maintenance. They are suitable for rural power grids, remote mountainous areas, scattered villages, agricultural production, lighting, and power consumption.Through optimized electrical design and the use of high-quality materials and components, WINLEY's pole-mounted transformers are safe, stable, and efficient, helping you reduce operating costs.

Pole Mounted Transformer​ Design Capability

Pole Mounted Transformer Type

WINLEY offers a comprehensive range of pole-mounted transformers, including both three-phase and single-phase models, as well as conventional and completely self-protected (CSP).

[Conventional Type]

[CSP Type]

The CSP-type pole-mounted transformer features an integrated surge arrester on the high-voltage side, a circuit breaker on the low-voltage side, and a built-in protective fuse. This all-in-one design eliminates the requirement for separate protective devices, significantly reducing installation costs. The following additional features are all standard on self-protected type CSP units：

• Primary protective link
• Surge arrester
• Secondary circuit breaker
• Secondary breaker operating handle with emergency overload reset
