UNSPSC 39121037: Limiting transformer

Transformer used when boosting or stepping down voltage for application in households, offices or others, and used for small capacity devices.

UNSPSC 39121037 Limiting transformer is a Commodity code. State and local governments procure distribution transformers, pad-mounted transformers, substation power transformers, pole-mounted transformers, and specialized testing equipment under this code. Recent opportunities show utilities and municipal power departments buying pole-type distribution transformers (typically 100–1,500 KVA at 240–480V or 13.8 kV systems), pad-mount transformers in single-phase and three-phase configurations, large substation transformers (20–50+ MVA at 115 kV and higher), and precision high-voltage test modules compatible with existing OMICRON test systems. Issuing bodies span municipal utilities (Kissimmee Utility Authority, Austin Energy, Lubbock Power & Light, Keys Energy Services, City of Palo Alto), county and city power departments (Covington, Monroe, Fairburn, Albany, College Park, Athens-Clarke County), regional cooperatives (Florida Keys Electric Cooperative), and state procurement offices (Texas Department of Criminal Justice, Florida Department of Agriculture). Repeat buyers include Kissimmee Utility Authority (two test-equipment solicitations within the past month) and Lubbock Power & Light (multiple component and transformer RFPs).

Geographic activity concentrates in Florida, Georgia, and Texas, with recent solicitations also posted from Connecticut, Virginia, and California. Representative opportunities include Lubbock Power & Light's RFP 7133-26-ELD for a 30/40/50/56.2 MVA, 115–12.47 kV three-phase power transformer for Oliver Substation with an August 5, 2026 deadline; Austin Energy's IFB 1100 AGM1008 for capacitor banks and associated parts on an as-needed basis under a 24-month term with local business and small business preferences (up to 5% discount for bids under $500,000), bids due October 27, 2026; the City of Palo Alto's pre-qualification of vendors for six 20/26/34 MVA substation transformers (115/60–12.47Y/7.2 kV) with questionnaires due and evaluation criteria emphasizing ISO 9001 and ISO 45001 certification; and the Texas Department of Criminal Justice's RFP 696-FD-26-P036 for electrical system replacement at Memorial Unit in Rosharon, involving two redundant 2500 KVA transformers and 12.5KV/4160V distribution loops, with proposals due June 8, 2026 and an estimated project budget of $6.8 million. Kissimmee Utility Authority's sole-source Notice of Intent for an Omicron CP TD12 Testing Device (SS26040JG, due May 28, 2026) and competitive IFB 26046JG for the same module (due September 22, 2026) illustrate testing equipment procurement tied to substation maintenance. Florida Keys Electric Cooperative's FKECBID2620 for 14 ABB-Elastimold 27 kV reclosers and 35 units of 1 kVA overhead transformers, quotes due November 3, 2026, shows materials procurement for system-wide recloser installation projects. Utility contracting licenses and manufacturer experience requirements (typically five to ten years for transformers and substation equipment) are standard; evaluation often includes total cost of ownership models, loss warranties, delivery schedules, and on-site installation and testing capability.
