About this file
This document contains the Salient Characteristics for the requested pad mount and pole mount transformers under the federal contract opportunity FA4610Q0222 issued by the Department of the Air Force Space Command.
The key details are:
- All transformers are required to have copper windings, stainless steel tanks/construction, FR3 insulation, and be made in the USA.
- Pad mount transformers must have dead front loop feed, tap changers, and bayonet fusing.
- Specific technical requirements are provided for temperature rise, cooling class, insulating fluid, elevation, sound level, efficiency, harmonic factor, voltage class, taps, bushings, overcurrent protection, and other design elements.
- The federal contract opportunity is for the purchase of five medium voltage pad-mounted transformers of varying kVA ratings (122.5 kVA, 150 kVA, 300 kVA, 500 kVA, 750 kVA) to replace aging equipment at Vandenberg Space Force Base, which has a corrosive environment requiring the unique stainless steel construction.
