Denton seeks utility PTs, CTs, and CCVTs for high-voltage systems

The City of Denton is seeking proposals for high-voltage instrument transformers to support its electric utility system. - Government buyer: City of Denton, Denton Purchasing / Purchasing and Materials Management. - Procurement: Supply completely assembled and tested potential transformers (PTs), current transformers (CTs), and capacitor-coupled voltage transformers (CCVTs) for utility systems from 13.2 kV through 345 kV. Respondents must identify the manufacturer and catalog number for proposed equipment; no transformer OEM or supplier is specified. - Estimated five-year quantities: 3 each 69 kV PTs, 80 each 138 kV PTs, 36 each 345 kV PTs, 3 each 69 kV extended-range CTs, 6 each 138 kV extended-range CTs, 36 each 345 kV CCVTs, 3 each 13.2 kV dry-type PTs, and 3 each 24.9 kV dry-type PTs. No part numbers are specified. - Named manufacturers: Burndy (YA28A5) and Anderson (VACL4012BN) are cited only as examples of compatible grounding lugs, not as required brands or selected suppliers. No other transformer OEMs or vendors are named. - Notable technical requirements: Equipment must meet applicable ANSI and IEEE standards, be factory tested with certified reports, and include drawings and product documentation. CTs require shorting-type secondary terminal boards that permit ratio changes without taking a CT offline. Dry-type 13.2 kV and 24.9 kV PTs are specified with cast hydrophobic cycloaliphatic epoxy or an equal material. - Delivery and warranty: FOB-destination delivery to the Spencer Utility Site or other Denton-area substations; units must ship fully assembled on open flatbed trucks. A manufacturer warranty must remain in effect for at least 12 months after first energization, with replacement units provided at no charge and delivered within 60 days of a replacement request. Proposals must provide delivery schedules and include delivery-related costs. - Contract term: One-year initial term, with four optional one-year renewals and a possible extension of up to six months. Listed quantities are estimates over five years.
