Federal Pacific History

In 1987, the Electro-Mechanical Corporation acquired the dry-type transformer division of Federal Pacific Electric in Des Plaines, Illinois. It was moved to Bristol, Virginia and the name was changed to Federal Pacific (FP). A new 100,000 square foot facility was constructed where time-proven designs and modern technology were combined and deployed under new management. Expansion in early 1993 provided an additional 36,000 squarefeet ofmanufacturing space.

Federal Pacific Today

Federal Pacific is a major manufacturer of dry-type transformers which serve the industrial, construction, commercial, mining, OEM and utility markets. The product scope is 50 VA through 10,000 KVA and 120 volts through 25,000 volts. The 600 volt class offering includes industrial control transformers, encapsulated/compound-filled general purpose and buck-boost transformers, ventilated designs for general purpose applications, electrostatically shielded transformers and a complete line of motor drive isolation transformers. The medium voltage offering includes core and coil transformers, general purpose designs, pad-mount transformers, unit substation transformers, vacuum pressure impregnated transformers (VPI), and vacuum pressure encapsulated (VPE) transformers. K-Factor rated transformers are offered for the entire product scope.

Distribution

Regional warehouse stocks have been implemented across the United States, ensuring quick delivery of all products anywhere in the country.

Single & Three Phase Encapsulated and Ventliated Transformer Naming Convention

(using T48LH2Y-75 as an example)

T = Three Phase, Ventilated

N = Three Phase, Encapsulated

T
