UNSPSC 39121045: Modulation transformer

A transformer that is used to match the impedance of the coil on secondary output from the amplitude modulation circuit.

UNSPSC 39121045 Modulation transformer (Commodity) reflects state and local procurement activity centered on power distribution equipment installation and replacement at utility and municipal facilities, rather than modulation-specific transformer components; recent solicitations show governments purchasing distribution transformers, step-up transformers, pad-mount transformers, and high-voltage switchgear equipment as part of larger electrical infrastructure projects. State and local issuing bodies soliciting under this code span utility departments, city procurement offices, school districts, universities, and special-purpose authorities. The City of Cumming, Georgia is executing a turnkey generator and switchgear project requiring a 3,750 kVA step-up transformer and 3,000 A, 5 kV paralleling switchgear as of August 7, 2026 (RFP deadline), while Lubbock Power & Light is procuring a 50 MVA, 115–12.47 kV three-phase power transformer for Oliver Substation delivery by April 3, 2028 (RFP 7133-26-ELD, proposals due August 5, 2026). The City of Albany, Georgia issued sealed bids for twelve 100 kVA and three 167 kVA pad-mount transformers (Bid 26-055, closed June 8, 2026), and the City of Austin posted an RFP for 285 units annually of three-phase pad-mounted distribution transformers ranging 75–2500 kVA across 20 configurations on an as-needed basis (RFP 1100 EAL3030, proposals due April 21, 2026).

Geographic activity concentrates in Texas, Georgia, and California, with secondary opportunities in Florida and Mississippi. Recent solicitations show steady demand from municipal utilities, water departments, transit authorities, and higher-education institutions pursuing electrical system upgrades and capacity expansion. The City of Fairburn, Georgia is installing underground primary distribution systems with pad-mount transformers and associated switchgear (IFB 26-016, closed July 22, 2026), while the Texas Department of Criminal Justice is replacing a 4,160-volt radial electrical distribution system at Memorial Unit requiring two redundant 2,500 kVA transformers and outdoor/indoor distribution loops (RFP 696-FD-26-P036, $6,806,200 budget, proposals closed June 8, 2026). The University of Mississippi is executing 13 kV electric distribution improvements at its NW Mechanical Plant (pre-bid February 3, 2026; bids closed February 26, 2026). Procurement activity demonstrates sustained investment in utility infrastructure modernization, with most opportunities structured as sealed competitive bids or proposals requiring professional engineering seals, performance and payment bonds, insurance certifications (typically $1 million general liability minimums), and compliance with prevailing wage, E-Verify, and security clearance requirements where applicable.
