About this opportunity
The Department of the Army Materiel Command Mission and Installation Contracting Command Fort Drum seeks procurement of one pad-mounted transformer rated 750 kVA, 13.2 kV primary / 208Y/120 V secondary, with proposals due July 29. The procurement is a Total Small Business set-aside.
Place of performance is Fort Buchanan, Guaynabo, Puerto Rico. The transformer must be a three-phase, 60 Hz unit with ONAN cooling and mineral oil, dead front construction, stainless steel tank and cabinet (304), and radial feed configuration. Mandatory dimensions are height 63 to 64 inches, width 65 inches, and depth variable (existing unit is 41 inches); the contractor shall confirm manufacturing dimensions in writing or by shop drawing for government approval.
Electrical requirements include primary bushings with six 200 A load break wells (inserts for three LV and three 10 kV arresters), NEMA spade secondary terminals with supports (10 holes for three LV and one neutral per ANSI), standard ANSI impedance values, and 2 by 2.5 percent no-load tap changer. Protection and monitoring equipment required includes bayonet fuse with isolation link, current limiting fuses, two-position load break switch, nitrogen pressure gauge with test port and blanket, temperature gauge, pressure vacuum gauge, liquid level indicator, and Schrader valve; all gauges must be visible. Construction must include pentahead security hardware, ANSI 61 grey color, welded and sealed tank with pressure test, one-inch oil drain valve on primary side with 3/8-inch water sampler, arc-flash and safety labeling, and lifting and jacking hardware.
The transformer must comply with ANSI/IEEE C57.12 series, DOE 2016 efficiency standards, and National Electrical Code requirements. NAICS code is 335311, Power, Distribution, and Specialty Transformer Manufacturing; PSC is 6120, Transformers: Distribution and Power Station.
