UNSPSC 39121022: Electronic transformers

These are diode-based electronic transformers.

UNSPSC 39121022 Electronic transformers, a Commodity code, covers single-phase and three-phase distribution transformers, protection and automation relays, motor control centers, electrical components (ballasts, capacitors, solenoids), and associated enclosures that state and local governments procure for utility infrastructure, water treatment, transit, and municipal building operations. Recent solicitations show utilities and transit authorities as primary buyers, with water districts, counties, school districts, and cities purchasing transformers and related electrical equipment for system replacement, maintenance, and emergency operations. The work includes supply and installation of utility-grade outdoor pole-mounted transformers, medium-voltage pad-mounted units, feeder protection relays with integrated bay control and automation functionality, control panel fabrication with UL 508A certification, and standardized electrical component kits for SCADA integration and motor control applications.

Recent activity spans Florida, Texas, Georgia, Connecticut, and California. Kissimmee Utility Authority (Florida) issued a sole-source RFQ for SEL protection and feeder relays requiring full interoperability with existing SCADA infrastructure (due August 24, 2026, since passed). Hillsborough County Board of County Commissioners (Florida) solicited pump station control panels and other enclosures under ITB 26-00393, with bids due September 29, 2026 at $3.66 million over two years, requiring UL 508A certification and weekly fabrication capacity of two to four complete panels plus other enclosures. The City of Norwich, Connecticut requested bids on polemount distribution transformers (13.8 kV Grounded Wye, 7.97 kV, and 4.8 kV Delta systems) under ITB 27-06 (due August 13, 2026). California Department of Developmental Services posted an IFB to replace electrical transformers at Porterville Developmental Center, with a mandatory pre-bid meeting on May 14, 2026 and bid opening June 12, 2026. Gwinnett County, Georgia (Parks and Recreation) sought annual contract quotes for ballasts and capacitors on an approximately 200-unit-per-year basis (due June 12, 2026). Trinity Metro (Tarrant County, Texas) established an IDIQ electrical parts supplier contract for facilities maintenance and emergency operations (proposals due August 20, 2026). Northside Independent School District (San Antonio, Texas) issued IFB 2026118 for electronic equipment, parts, repairs, rentals, and services to replace expiring IFB 2024-160 (proposals due September 24, 2026).
