About this file
This document is a detailed equipment data sheet for a high voltage circuit breaker procurement for Boulder City Substation #3, likely involving a municipal or utility agency. The project involves purchasing two 69kV 2000A circuit breakers with specific electrical requirements, including a rated maximum voltage of 72.5 kV, basic impulse lightning level of 350 kV peak, and a rated short-circuit current of 40 kA. The circuit breakers are intended for transformer switching, with no field services required. The quote is dated 6/26/25, with a project number of 185915 and revision 0.
The equipment specifications indicate operational parameters for standard utility infrastructure, with an ambient temperature range of -30°C to +40°C and compliance with specific technical standards. The circuit breakers are classified as S2 with a first pole to clear factor of 1.5, designed for an effectively grounded system with a system X/R ratio of 17. While pricing details are not explicitly provided in the document, the comprehensive technical specifications suggest a precise procurement process for critical electrical infrastructure components, likely through a competitive bidding or proposal process typical of municipal utility projects.
