UNSPSC 39121041: Constant voltage transformer

Transformer used for computer department or precision machine and devices that requires uniform voltage at all times, and has constant voltage device by utilizing the principle of parallel ferro resonance.

UNSPSC 39121041 Constant voltage transformer is a Commodity code that encompasses voltage regulation and transformation equipment state and local governments procure for utility infrastructure, facility power distribution, and emergency backup systems. Recent opportunities show this code applied to a mixed portfolio of utility-scale power distribution equipment including step-up transformers (3,750 kVA units), pad-mounted distribution transformers (75 kVA to 2,500 kVA units), and high-voltage substation transformers (50 MVA class), alongside general-use power distribution and transformation components specified in broader electrical supply contracts. The issuing bodies are predominantly municipal utilities and city governments, with secondary activity from county public safety departments, school districts, state technical colleges, and public universities. Lubbock Power & Light, the City of Austin (Austin Energy), the City of Albany Georgia, and the City of Cumming Georgia appear as repeat or recent procurers. The geographic spread spans Texas, Georgia, Florida, Arizona, California, and Mississippi, with concentrated recent activity in Georgia and Texas municipal utilities.

Representative recent opportunities include the City of Cumming, Georgia's PWPF Generator and Switchgear Project (RFP, proposals due August 7, 2026), a turnkey installation of 2,500 kW diesel generators with a 3,750 kVA step-up transformer and 3,000 A switchgear; Lubbock Power & Light's RFP for a 50 MVA, 115–12.47 kV three-phase power transformer for Oliver Substation (RFP 7133-26-ELD, due August 5, 2026), evaluated on specifications (15%), life-cycle cost including 30-year maintenance (30%), delivery schedule (40%), proposal completeness (5%), and references (10%); and the City of Austin's three-phase pad-mounted distribution transformer RFP (RFP 1100 EAL3030, due April 21, 2026) for an estimated 285 units annually across 20 configurations, evaluated on technical understanding, delivery lead time (30 points), prior experience, total annual owning cost, and local and small-business preferences. The City of Albany's sealed-bid procurement for pad-mounted transformers (Bid 26-055, due June 8, 2026) and the City of Fairburn's underground primary distribution installation (IFB 26-016, due July 22, 2026) demonstrate routine specification and delivery activity tied to broader utility grid modernization and electrification projects.
