About this opportunity
The Department of the Air Force Air Mobility Command seeks quotations for a single 750 kVA 3-phase pad-mount transformer, with proposals due June 12, 2026 at noon CST. This is a total small-business set-aside procured under FAR Part 12 procedures.
Place of performance is Scott Air Force Base, Illinois. The transformer must be manufactured with copper windings, meet DOE 2016 efficiency standards, and utilize Envirotemp FR3 insulating fluid. High-voltage specifications include 12470GY/7200 volts at 15 kV class with 95 kV BIL, dead-front primary termination with loop feed, and a 5-position tap changer with 2.5% taps above and below nominal. The unit requires six 200-amp Cooper bushing wells with removable studs, six 15 kV load-break inserts, three 15-38 kV 300A 2-position loadbreak switches, and three Varistar elbow arresters at 15 kV class. Low-voltage specifications designate 480Y/277 volts at 1.2 kV class with 30 kV BIL, live-front secondary termination, and radial feed. Overcurrent protection includes bayonet fuses in series with partial-range current-limiting fuses. Cabinet construction requires 304L stainless steel for sill, sides, and tank base with Federal Spec Sherwin Williams 6006 black bean brown paint. No fixed delivery deadline is imposed; the transformer serves as backup equipment.
NAICS Code 335311 and PSC Code 6120 apply. Evaluation uses Lowest Price Technically Acceptable (LPTA) criteria with a single award. Delivery is FOB Destination. Offerors must maintain active SAM registration. The specification was updated June 4, 2026 to mandate copper windings, superseding prior winding material requirements.
