Green Line High Efficiency Transformers

Recent advances in materials and design tools mean Rex Premium High Efficiency transformers will pay back rapidly for the investment.

As you already know The Energy Policy Act of 2005 (EPACT 2005) requires that Low Voltage Dry Type Distribution Transformers (Input Voltage 600 or less) manufactured after January 1, 2007, meet the Class I Efficiency Levels for distribution transformers specified by NEMA TP-1 standards. The DOE officials also advised in 2006 that efficiency standards for Medium Voltage Dry Type Distribution Transformers (Input voltage of 601 Volts to 34.5 kilovolts) are expected to come into effect around the year 2010. With the DOE Final Rule published Oct.12 2007 these new efficiency levels for Medium Voltage Transformers come into effect on January 1, 2010. The regulations already in effect for Low Voltage Distribution Transformers remain unchanged.Recent advances in materials and design tools mean Rex Premium High Efficiency transformers will pay back rapidly for the investment.
