DOE 2010 efficiency standards
On January 1, 2010, new Department of Energy efficiency standards for distribution transformers 2500 KVA and below went into effect. Transformer pricing has risen due to the use of higher quality materials needed to achieve the standards. The new standards are not applicable to transformers manufactured prior to January 1, 2010, nor to transformers that are remanufactured or reconditioned. For more information visit 10 CFR Part 431 Subpart K at GPO Access.
high voltage dry type transformers
Alfa Transformer stocks remanufactured and reconditioned, medium and high voltage, three-phase dry type transformers through 2500 KVA.
Alfa also provides standard and custom designs through 10 MVA, up to 35kV. Transformers can be designed to meet existing specifications, fit into existing enclosures, or between primary and secondary switchgear.
low voltage dry type transformers
Alfa Transformer can ship new, 600V class, three-phase and single-phase dry type transformers through 500 KVA from warehouses across the U.S. Available in ventilated, encapsulated, and open core and coil designs. Alfa also stocks motor drive isolation transformers up to 770 KVA.
If you have a special application, Alfa Transformer can have a transformer designed, built and shipped in as little as a few days.
pad mounted transformers
Alfa Transformer stocks new, remanufactured, and reconditioned three-phase and single-phase pad mounted transformers through 2500 KVA.
Alfa offers standard and custom designs through 10 MVA, up to 69kV primary voltages and up to 25kV secondary voltages.
Pad mounted transformers are available with standard and optional accessories and in many connection configurations.
substation transformers
Alfa Transformer provides three-phase and single-phase substation transformers up to 300 MVA, 230kV with the fastest lead times in the industry. Standard design and custom-designed units are available. Alfa offers designs for explosion-proof, 6-pulse, and other special applications.
On many power transformers Alfa offers additional services such as offloading, setup, installation, filling with oil, and more.
pole mounted transformers
Alfa Transformer offers new and reconditioned pole mounted transformers through 333 KVA, primary voltages up to 35kV and secondary voltages up to 5kV.
Pole mounted transformers are available in two-bushing conventional and CSP designs. Many reconditioned transformers can be shipped within 24-48 hours.
