Eaton's Cooper Power series PEAK three-phase pad-mounted transformer is filled with FR3 dielectric fluid and is uniquely designed to manage increased loads and temporary overload capacity without loss of life expectancy compared to mineral oil-filled alternatives. Offering the ability to operate beyond full rated load from 12% to 22%, the transformer’s smaller, lighter footprint further enhances value.
Cargill's FR3 dielectric fluid provides superior transformer performance, safety and environmental friendliness.
