- Description
- Notice of intent to use a brand name product. The Naval Facilities Engineering Command, Pacific (NAVFAC Pacific) is performing a market survey to determine if other potential sources of supply can provide for a medium voltage vacuum circuit breaker interoperable with the existing Westinghouse VAC-CLAD switchgear. The distribution and control business unit of Westinghouse was acquired by Eaton Corporation in 1994. FY20 Unspecified Minor Construction Project P-216, UEM Interconnect Station C to Hickam, Joint Base Pearl Harbor-Hickam, Pearl Harbor, Hawaii, requires a vacuum circuit breaker with the following characteristics: 1. The vacuum circuit breaker shall be fully interoperable with the existing Westinghouse VAC-CLAD switchgear S.O.# 71Y1267 and G.O.# HL-46302-Y1. The vacuum circuit breaker shall maintain the Short Circuit Current Rating of 18 kAIC and shall be UL-listed. Interphase barrier for type VCP breakers is part of the switchgear compartment and is not required to be provided with the circuit breaker. A safety interlock is provided that prevents the insertion of the breaker into the test position unless the barrier is in place. 2. The vacuum circuit breaker shall be an electrically operated, three-pole, circuit interrupting device rated 13.8 kV nominal voltage. The vacuum circuit breaker shall be rated for 1200 A continuous current at 60 Hz and at maximum voltage of 15 kV and 110 kV BIL. The vacuum circuit breaker shall be designed for service on a 11.5 kV system with a short-circuit capacity of not less than 500 MVA. The rating shall be based on IEEE C37.04 and IEEE C37.06. The vacuum circuit breaker shall be horizontal draw-out type with position indicator, operation counter, auxiliary switches, and primary and secondary disconnect devices. Circuit breaker shall be operated by an electrically charged, mechanically and electrically trip-free, stored-energy operating mechanism. Provide for manual charging of the mechanism and for slow closing of the contacts for inspection or adjustment. Circuit breaker control voltage shall be 125 VDC. 3. The vacuum interrupter shall be mounted vertically in a molded pole base and supported from the fixed stem clamped to the top conductor. Multiple sliding finger type primary disconnects at the ends of the top and bottom conductors shall provide means for connecting and disconnecting the vacuum circuit breaker to the primary stabs in the switchgear compartment. Additional requirements include: a. Contact wear gap indicator to determine erosion of contacts. b. Ground contacts to provide a means for grounding the breaker chassis when it is inserted into the switchgear compartment. c. Undervoltage trip device that trips the breaker when the voltage on its coils falls to between 60 and 30 percent of nominal. d. Breaker - Compartment Code Plates to prevent insertion of lower rated breaker into higher rated compartment. e. Anti-Close Interlock that prevents releasing the closing springs electrically or manually when the breaker is closed. f. Floor Tripping and Spring Release Interlocks that provide the following functions: - Hold the breaker in the trip free mode between the test and connected positions. The latch check switch is also held open thus preventing any electrical close signal. - Permit the breaker to be withdrawn in safe mode (breaker open, springs discharged) when moved from the test to the withdrawn position or vice versa. Note that there is never a free discharge of the closing springs that unduly imposes heavy stresses on the mechanism parts. - Trip the breaker (if closed) before being levered from test position. g. Levering Interlock to prevent engaging the levering crank when the breaker is closed in the connected position. h. Mechanism-Operated Cell and Truck-Operated Cell Switch Operators This notification is for market research purposes only to identify if other potential sources of supply can meet the requirements of the Government. This is not a request for proposals, quotes or an invitation for bid. The intent of this notice is to identify other potential sources for this product. To be considered, please submit detailed technical data in order for the Government to conduct a comprehensive evaluation of your product to ensure compatibility with the existing system. In accordance with FAR 15.201(e), a response to this notice is not an offer and cannot be accepted by the Government to form a binding contract. The responder is solely responsible for the information it submits and any associated costs. The Government reserves the right to disregard any submittal that is incomplete or that is vague. Please do not submit your company brochures. Please submit your information via email to Shaun Chow at shaun.chow@navy.mil no later than 10:00 a.m. HST on April 5, 2019. Information received after this date and time will not be considered. NOTE: THIS NOTICE WAS NOT POSTED TO FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (19-MAR-2019); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE. PLEASE CONTACT 877-472-3779 or fbo.support@gsa.gov REGARDING THIS ISSUE.
