The Dalles Generator Step-Up Transformer Replacement

Added: Feb 09, 2016 5:41 pm Description of Requirement: Generator Step-up Transformer at the Dalles Dam, Dalles OR, 97058-0564. The Dalles Dam is undergoing an upgrade to the existing Step-Up Transformers and will be replacing the existing systems. The project will eventually replace a total of nineteen transformers of various specifications over the course of the next several years.
