UNSPSC 39121044: Audio frequency transformer

Transformer used in conversion of voltage in the audio frequency range.

UNSPSC 39121044 Audio frequency transformer is a Commodity code. State and local governments use this code narrowly: the recent solicitations show utilities purchasing high-voltage testing equipment, distribution and substation transformers, capacitor banks, and associated electrical distribution components for system maintenance, operation, and infrastructure upgrade projects. The Kissimmee Utility Authority's procurement of an Omicron CP TD12 testing device (sole-source, alternative vendors considered), Florida Keys Electric Cooperative's request for ABB reclosers and overhead transformers for 2027 system-wide installation, and Austin Energy's as-needed supply contract for capacitor banks and related parts all exemplify the range of equipment state and local utilities actually buy under this code. Issuing bodies span municipal electric utilities (Kissimmee Utility Authority, Austin Energy, Lubbock Power & Light, Keys Energy Services, City of Leesburg), electric cooperatives (Florida Keys Electric Cooperative), city power and water departments (City of College Park, City of Cumming), and regional government purchasing on behalf of state criminal justice facilities (Texas Department of Criminal Justice). Repeat buyers include Lubbock Power & Light, which posted multiple RFQs and RFPs for transformers and electrical equipment within a six-month window, and municipal utilities across Florida and Georgia.

Recent activity concentrates in Florida, Texas, and Georgia. Representative opportunities include Florida Keys Electric Cooperative's RFQ for 14 reclosers and 35 overhead transformers due November 3, 2026 (two-phase 2027 installation project); Austin Energy's IFB 1100 AGM1008 for capacitor banks and parts as of October 27, 2026, with local business preferences up to five percent and initial contract term of 24 months; Lubbock Power & Light's RFP 7133-26-ELD for a 30/40/50/56.2 MVA power transformer for Oliver Substation due August 5, 2026, with liquidated damages at $1,000 per day for late delivery and 30-year life-cycle cost evaluation; and Kissimmee Utility Authority's sole-source notice for the Omicron CP TD12 device with alternative-vendor submissions due May 28, 2026, requiring written documentation of specification compliance. Specifications across these opportunities are highly technical, typically reference manufacturer part numbers or equivalents, demand compliance with ANSI and IEEE standards, and commonly impose strict performance metrics (e.g., 95 percent on-time delivery, specific voltage and current ratings, temperature operating ranges). Delivery requirements are routinely tight—Austin Energy requires arrival within two calendar days of order placement at two warehouse locations; Florida Keys Electric requires delivery to Tavernier Operations Center—and evaluation often weights cost, manufacturing quality, and delivery availability equally or nearly so.
