Appendix VIII: Quarry Substation Equipment Inventory

This appendix provides the detailed equipment inventory and specifications for the Quarry Substation, one of seven substations included in the City of Palo Alto Utilities' electric substation equipment painting project. The Quarry Substation contains ten items requiring surface preparation and protective coating services, including two transformers (National Industries XF QR 20 and XF QR 21, each measuring 207"w x 146"d x 164"h with galvanized radiators), one Peterson switchgear unit (356"w x 195"w x 119"h) serving items 20 and 21, two Siemens circuit breakers (GCB 52QR 20 and GCB 52QR 21, model SP 72), two additional transformers (KHULMAN XF QR 22 and XF QR 23, each measuring 159"w x 161"d x 161"h), a second Peterson switchgear unit (356"w x 195"w x 119"h) serving items 22 and 23, one Westinghouse oil circuit breaker (OCB 52QR, model 690-G-3500), and one capacitor house by Butler (15'd x 45'w x 12'h). The Quarry Substation represents a mid-sized component of the overall project, with Year 1 painting costs estimated at $167,000. The appendix includes corresponding photographs and detailed images documenting each equipment item to support contractor planning and execution of the painting and protective coating services.
