Liquid filled transformers are filled with non-combustible mineral oil that is used to insulate internal parts of the transformer. They are usually used for large projects and can operate heavy machinery for long periods of time. Liquid filled transformers are custom built to include certain features based on their application and voltage demands.

 

Our voltage regulators are manufactured with exceedingly high safety, durability and performance standards. Niagara Transformer's liquid filled transformer specifications include:
