DOE
Three Phase 15 to 1000 kVA
Our new line of general purpose transformers not only meets but exceeds the new, more stringent DOE 2016 Energy Efficiency
Standards.
Designed with feedback from our customers, the line is fully compatible in size with comparable transformers meeting the old 2007
TP-1 standards.
Replacing older general purpose transformers with our DOE 2016 compliant equipment will result in increased profitability from
lower operating costs as well as a positive impact on the environment from a reduced carbon footprint.
Features:
Q
Core Design. Cores are high-quality electrical steel from industry-leading suppliers
Q
3R Compliant. All new units ship with weather shields already installed
Q
Flexibility. When a weather shield is not needed, it can easily be removed
Q
Terminal Lugs. Primary and secondary terminals come standard with lugs (up to 112.5kVA) for quicker, easier connections
Q
Isolating Pads. Extra padding reduces noise and vibration, assuring quiet operation
Q
Aluminum Windings. Aluminum provides increased insulation life, cooler operation, and lower losses
Q
Consistent Fit/Form. Enclosure sizes of DOE 2016 units are identical to TP-1 sizes
