CRCBC-06 15kV Power Circuit Breakers

The Colorado River Commission is soliciting bids for the production of 15kV power circuit breakers. The bid solicitation is for the supply of three-phase, medium voltage, vacuum insulated, dead tank circuit breakers, maintenance tools, and spare parts. The circuit breakers should conform to the requirements of IEEE Std. C37.04 and C37.06.1, and should be suitable for operation in a power system with characteristics such as three-phase, 60 Hertz, and effectively grounded or non-effectively grounded. The bid should include a complete set of special tools, wrenches, and other equipment necessary for maintenance. The supplier should also provide a technical description of all tests and record the results. • The circuit breakers should have a vacuum interrupting medium and should be capable of successful load interruption up to the rated continuous current. • The circuit breakers should have a mechanical endurance as indicated on the CIRCUIT BREAKER DATA SHEET. • The supplier should provide a pre-connectorized system for interconnecting wiring between poles. • The circuit breaker control system should have capability for single-pole and three-pole operation. • The supplier should provide a system to determine breaker contact travel time for contact maintenance.
