Unit Auxiliary Transformers (UAT)


These high-performance transformers are designed for abnormal voltage fluctuation, and also have the added benefit of having a low flux density. These liquid-based transformers function on mineral oil or any one of many different liquids. These transformers tend to have a much longer working life than comparable transformers, while also maintaining a manageable maintenance cost.

Transformer Specifications

The largest benefit of this type of the Auxiliary Transformer is the multiple low-voltage windings, which allow the consumer to attach multiple generating units to be given auxiliary supply. Niagara Transformer’s superior engineering expertise paired with its unmatched years of manufacturing experience and high-grade materials allow them to provide the best in-class Auxiliary Transformers.
