UNSPSC 39121044: Audio frequency transformer

Transformer used in conversion of voltage in the audio frequency range.

UNSPSC 39121044 Audio frequency transformer is a Commodity code. State and local governments procure transformers—primarily power distribution and step-up units for utility infrastructure, water treatment facilities, and electrical system upgrades—under this and closely related transformer categories. The recent solicitations show substantial activity in high-voltage distribution transformers (ranging from 112 kVA to 50 MVA), pad-mounted distribution units (100 to 167 kVA), and specialized step-up transformers integrated into larger electrical infrastructure projects. Issuing bodies span city utility departments (Cumming, Georgia; Austin, Texas; Albany, Georgia), public power cooperatives (Lubbock Power & Light), state agencies (Florida Department of Agriculture; Texas Department of Criminal Justice), county parks departments (San Mateo County), and university facilities management (University of Mississippi). School districts and transit authorities also source electrical equipment under related codes, though transformer-specific procurements in this sample appear concentrated among utilities and state infrastructure agencies.

Recent opportunities cluster in Texas, Georgia, and Florida, with additional activity in Mississippi and California. Representative current solicitations include the City of Cumming's PWPF Generator and Switchgear Project (RFP, proposals due August 7, 2026), which specifies a 3,750 kVA step-up transformer as part of a turnkey 2,500 kW generator installation at a water production facility; Lubbock Power & Light's RFP 7133-26-ELD for a 50 MVA, 115-12.47 kV three-phase power transformer for Oliver Substation (proposals due August 5, 2026, with April 2028 delivery); the City of Albany's Bid 26-055 for twelve 100 kVA and three 167 kVA pad-mount transformers (sealed bids due June 8, 2026, awarded on unit pricing with thirty-day delivery); and the City of Austin's RFP 1100 EAL3030 for three-phase pad-mounted distribution transformers in multiple configurations on an as-needed basis (285 units annually estimated, proposals due April 21, 2026). Transformer procurements often include ancillary switchgear, bushings, fuses, and installation or integration services, and response deadlines typically allow six to eight weeks from posting. Liquidity in utility infrastructure modernization and water/power facility upgrades is driving steady demand.
