NIGP 28542: Insulation Materials and Insulators: Compounds, Varnish, etc.

NIGP 28542 Insulation Materials And Insulators: Compounds, Varnish, Etc., an Item code, represents electrical insulation products and components that state and local governments procure as part of building electrical upgrades, equipment repairs, and infrastructure maintenance—though recent solicitations show the code capturing broader electrical subpanel installation and replacement work where insulators and electrical components serve as line items within larger scopes. Housing authorities, school districts, county departments, and special-purpose cooperative purchasing entities are the primary issuing bodies, with activity concentrated in California and Texas in the recent post-market. The Housing Authority for the City of Alameda and Alameda Affordable Housing Corporation have each posted major electrical upgrade projects requiring licensed electrical contractors to supply and install multiple subpanels with itemized cost breakdowns by component, including insulators, bus bars, and breakers. Northside Independent School District in San Antonio solicited electrical equipment, parts, supplies, and repair services via IFB, while the County of Orange Sheriff-Coroner Department requested purchase and delivery of electrical connectors, components, and miscellaneous parts including heat shrink tubing and solders for radio and audio/video equipment upkeep.

The two largest current opportunities are the Housing Authority for the City of Alameda's RFP for Parrot Garden Electrical Subpanel Upgrade Work (2026RFPAHAHD006PG), with proposals due October 22, 2026, and the Alameda Affordable Housing Corporation's RFQ for Esperanza Electrical Upgrade Renovation Work (2026RFQAAHCHD004ESPELECTRICAL), with qualifications due September 10, 2026. Both projects require itemized cost breakdowns by component and operate on three-year initial terms with two optional one-year renewal periods. Northside Independent School District's IFB 2026098 for electrical equipment, parts, supplies, rentals, repairs, and services closed July 1, 2026, and replaced an expiring contract; the County of Orange's IFB 0603029702SC for electrical connectors and components closed May 14, 2026. Sourcewell, a Minnesota cooperative purchasing vehicle, issued RFP 061626 for law enforcement equipment on behalf of multiple Washington counties and other participating entities, with proposals due June 16, 2026, available exclusively through the Sourcewell Procurement Portal.
