UNSPSC 39121032: Current transformer

A current transformer (CT) is a type of instrument transformer designed to provide a current in its secondary winding proportional to the current flowing in its primary winding.

UNSPSC 39121032 Current transformer is a Commodity code that captures state and local procurement of discrete power-distribution and electrical-equipment components, most recently characterized by bids and RFPs for medium- to large-scale transformers integrated into water utility, municipal utility, transit, and corrections-facility electrical infrastructure projects. Recent solicitations show government procurement of step-up transformers (3,750 kVA units), pad-mounted distribution transformers (100–167 kVA), high-voltage substation transformers (50 MVA), and replacement transformers for specialized facilities, alongside broader electrical-equipment frameworks that bundle transformers with switchgear, controls, and installation services. Issuing bodies span city utilities (Cumming, Georgia; Albany, Georgia; Fairburn, Georgia; Austin Energy), independent power utilities (Lubbock Power & Light), state agencies (Texas Department of Criminal Justice; Florida Department of Agriculture and Consumer Services; University of Mississippi), school districts (Pinellas County Schools; Northside Independent School District), and transit authorities (Charlotte Area Transit System). City utility departments and state infrastructure agencies represent the most active repeat buyers in the recent opportunity set.

Geographic activity is concentrated in Texas, Georgia, and Florida, with secondary presence in California, North Carolina, Mississippi, and Arizona. Representative recent opportunities include the City of Cumming's PWPF Generator and Switchgear Project (competitive sealed proposals, due August 7, 2026) procuring a 3,750 kVA step-up transformer as part of a $25-fee-gated plan-holder process; Lubbock Power & Light's RFP for a 50 MVA three-phase transformer for Oliver Substation (proposals due August 5, 2026, award anticipated September 15, 2026, delivery by April 3, 2028); the City of Albany's sealed-bid procurement for twelve 100 kVA and three 167 kVA pad-mount transformers (bids due June 8, 2026); and the City of Austin's RFP 1100 EAL3030 for three-phase pad-mounted distribution transformers ranging 75–2500 kVA on an as-needed basis (proposals due April 21, 2026). The Texas Department of Criminal Justice's Memorial Unit electrical replacement (RFP 696-FD-26-P036, June 8, 2026 deadline, estimated $6.8 million budget) includes dual 2500 kVA transformers as core components. Most solicitations require delivery and installation, compliance with ANSI/IEEE standards, proof of manufacturing experience, insurance and bonding, and response to specification-based evaluation criteria.
