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 covering equipment and components used to step voltage up or down in electrical distribution systems. State and local governments procure transformers directly for installation at water treatment facilities, substations, and utility distribution networks. Sourcing includes new equipment purchased competitively from manufacturers and distributors, as well as services bundled with procurement—design, site surveys, testing, commissioning, operator training, and installation supervision. The issuing-body mix spans utility departments (city water and power authorities), state higher-education institutions, county parks departments, and specialized transit authorities. Cities of Cumming and Austin, Lubbock Power & Light, and the City of Dallas appear in recent activity; utility procurement is concentrated among municipal water and electric departments in mid-sized jurisdictions.

Recent solicitations reflect two procurement patterns. Turnkey installation contracts dominate: the City of Cumming, Georgia posted a competitive sealed proposal (RFP) for a 2,500 kW diesel generator system with a 3,750 kVA step-up transformer and switchgear at its potable water production facility, due August 7, 2026; the Texas Department of Criminal Justice solicited proposals for a two-phase electrical distribution system replacement at the Memorial Unit in Rosharon, involving two redundant 2,500 KVA transformers, with an estimated budget of $6,806,200.00 and a June 8, 2026 deadline. Standalone equipment procurement also appears: Lubbock Power & Light issued an RFP for a 50 MVA, 115–12.47 kV three-phase power transformer for Oliver Substation, due August 5, 2026; the City of Austin, operating as Austin Energy, sought three-phase pad-mounted distribution transformers ranging from 75 to 2,500 kVA on an as-needed basis, estimated at 285 units annually, through RFP 1100 EAL3030 due April 21, 2026. Geographic spread centers on Texas, Georgia, and California, with additional activity in Florida and Mississippi. The code shows steady quarterly activity tied to utility infrastructure maintenance and expansion cycles, particularly water and wastewater operations and utility substations.
