Polemount Transformer
Overhead type transformers for both large and small utility scale applications.
Capabilities
Polemounted transformers are the standard for single-phase and three-phase power distribution across much of the US. Rucker stocks many overhead type transformers for both large and small utility scale applications. Rucker specializes in selling polemount transformers to non-utility customers in the commercial and industrial space.
Product Details
Rucker liquid-filled polemount transformers are designed, built, and tested in accordance with all applicable IEEE standards. Each unit is built to comply with the latest DOE efficiency regulations. They are ideal for utility applications requiring single-phase and three-phase distribution.
