UNSPSC 39121042: Filament transformer

Transformer for power supply that heats the filament in electron tube, and used in adjusting line voltage.

UNSPSC 39121042 Filament transformer is a Commodity code that captures state and local government procurement of specialized high-voltage testing and measurement equipment, distribution transformers, pad-mount transformers, substation power transformers, and related electrical components for utility system maintenance, expansion, and emergency infrastructure projects. Recent solicitations show governments buying precision testing devices (such as OMICRON CP TD12 modules for dielectric and capacitance measurement), distribution transformers in multiple kVA ratings and voltage configurations for overhead and underground installations, pad-mount transformers for utility distribution loops, large substation power transformers rated in the 20–50 MVA range, and associated electrical materials including reclosers, capacitor banks, surge arresters, and structural steel for 115 kV installations. Issuing bodies include municipal electric utilities (Kissimmee Utility Authority, Austin Energy, Lubbock Power & Light, Keys Energy Services, City of Leesburg, City of Monroe), electric cooperatives (Florida Keys Electric Cooperative), city utility departments (City of Covington, City of Albany, City of College Park), county water and power authorities, and state agencies (Texas Department of Criminal Justice, City of Atlanta Department of Watershed Management). Some procurements are structured as sole-source or pre-qualification efforts for specialized equipment; others use open competitive sealed bids or RFPs with cost-of-ownership and lifecycle-loss formulas as evaluation drivers.

Activity concentrates in Florida, Georgia, and Texas, with secondary presence in Virginia, Minnesota, and California. Representative recent opportunities include Kissimmee Utility Authority's Notice of Intent to Sole Source an Omicron CP TD12 Testing Device with alternative-vendor submissions due May 28, 2026 (solicitation SS26040JG); Florida Keys Electric Cooperative's request for quotes on 14 ABB-Elastimold 27 kV reclosers and 35 overhead transformers for 2027 installation, with quotes due November 3, 2026 (FKECBID2620); Austin Energy's IFB 1100 AGM1008 for capacitor banks and associated parts on an as-needed basis with offers due October 27, 2026 at 2:00 p.m. CT and local business preferences of up to 5% discount; City of Covington, Georgia's sealed-bid procurement for five pad-mount transformers (2000 KVA, 1500 KVA, and 750 KVA units) due October 14, 2026 with local-vendor preference; Lubbock Power & Light's RFP 7133-26-ELD for a 30/40/50/56.2 MVA three-phase power transformer for Oliver Substation delivery by April 3, 2028, with proposals due August 5, 2026 and delivery liquidated damages of $1,000 per day; and City of Leesburg, Florida's RFP26017LK for design, manufacture, supply, and installation of one 67–13,090 kV three-phase power transformer at North Substation with continental U.S. manufacturing requirement, fall 2028 delivery, and 20-year cost-of-ownership evaluation model incorporating factory loss values. Utility procurement under this code emphasizes long lead times, detailed technical specifications, cost-of-ownership modeling, and compliance with IEEE and ANSI standards; many municipalities attach local-vendor and small-business preferences where statutory authority permits.
