Power transformers are extremely important in the electrical energy transfer process. Power transformers allow for the transfer of electrical energy from one circuit to another inductively. They provide high energy efficiency and cut down on energy loss, improving their economic benefit. Power transformers are commonly used in large industrial factories, power plants, transformer substations and chemistry factories.

Niagara Transformer is one of the industry leaders in power transformer manufacturing and offers both single and three phase power transformers.

Each power transformer from Niagara Transformer is built according to a customer's needs and transformer application. All our transformers meet strict electrical code standards and are manufactured to be durable and low-maintenance.
