UNSPSC 32121803: Microwave filter

UNSPSC 32121803 Microwave filter is a Commodity code that state and local governments use to procure electrical components and enclosures for water and wastewater utility operations, building infrastructure, and transit maintenance. Recent solicitations show that the code captures protection relays, control panels, motor control centers, electrical component assemblies, and related equipment used in SCADA systems, pump stations, lift stations, and utility distribution networks. Issuing bodies include county utility authorities (Kissimmee Utility Authority, Hillsborough County Board of County Commissioners, Bay County Board of County Commissioners), independent school districts (Northside Independent School District), municipalities (City of Tampa, City of Arlington, City of Fort Worth, City of Bartow), regional transit authorities (Trinity Metro), and county park departments (Gwinnett County Parks and Recreation). The work ranges from sole-source replacements of standardized relay systems to competitive sealed bids for fabricated control cabinets, multipurpose electrical materials contracts, and specific component procurements on as-needed bases.

Activity spreads across Florida, Texas, and Georgia in recent postings.
