1 Three-Phase transformers and substations COOPER POWER. SERIES. Effective January 2018. CA202001EN Supersedes October 2015. Substation Transformers-Unit and open types General Eaton designs its Cooper Power series Substation transformers to meet a wide variety of customer specifications. Flexibility in design, combined with the highest quality manufacturing processes, equipment, and testing procedures, enable Eaton to provide a product optimized to the customer's requirements. All units meet applicable American National Standards Institute (ANSI ), Institute of Electrical and Electronics Engineers, Inc.

2 (IEEE ) and National Electrical Manufacturers Association (NEMA ) standards, as well as National Electric Code (NEC ), Department of Energy (DOE). and Canadian Standards Association (CSA ). specifications. Substation transformers are available with cover- mounted bushings or sidewall-mounted bushings for connections to primary and/or secondary switchgear. Substation transformers are made with a wide range of core steels and winding conductors to optimize efficiency versus cost. Flexible core/coil and tank construction enable your dimensional requirements to be met.

3 Eaton's Cooper Power series transformers are available with Envirotemp FR3 fluid, a less-flammable and bio-degradable fluid, or electrical grade mineral insulating oil. Substation transformers intended for indoor use are solely filled with Envirotemp FR3 fluid, which meets Occupational Safety and Health Administration (OSHA) and Section , 2014. NEC requirements. Electrical codes recognize the advantages of using Envirotemp FR3 . fluid both indoors and outdoors for fire-sensitive applications.
