Clemson University Ionwave #6140AP

Clemson University medium-voltage switchgear and relay package

Clemson University is seeking two custom medium-voltage switchgear sections that integrate with its existing Siemens West Campus equipment. - Government buyer: Clemson University; the referenced installation is at Clemson University–West Campus. Delivery is to Clemson, South Carolina. - OEMs and named manufacturers: Siemens Industry Inc. is identified on the existing GMSG/GM-SG switchgear drawings and is the OEM of the equipment the new sections must interface with. SEL is specified for the SEL-751 feeder protection relay family, or an approved compatible relay. - Main equipment: Two indoor, 15 kV-class metal-clad switchgear sections for a 12.47 kV system, each with provisioned upper and lower compartments and a middle relay/wiring compartment; two 1200 A, minimum 40 kA horizontal drawout vacuum breakers; 3000 A silver-plated copper main bus with 63 kA symmetrical bracing; and 1200 A silver-plated copper ground bus. - Protection and accessories: Twelve 1200:5 MD-MR current transformers; twelve 3000:5 Type MD current transformers (part number 62300066302); six 9 kV surge arresters; two feeder relays (SEL-751 or compatible); and the specified relay test provisions, breaker and selector switches, indicators, control and lockout relays, terminal blocks, heaters, lighting, labels, and cable termination hardware, including 12 sets of 350 kcmil tinned-copper two-hole compression lugs. - Compatibility and technical requirements: New sections must be mechanically, electrically, and operationally compatible with the existing Siemens GMSG lineups. The supplier must verify and certify the interface before manufacture and furnish all transition bus, splice hardware, adapters, barriers, wiring, terminations, and other components needed for a complete operable installation. Comparable alternatives may be proposed subject to approval and documented compliance. - Services and deliverables: Provide equipment engineering and submittals, routine factory testing and certified reports, factory acceptance testing, manuals, installation and field-assembly instructions, and interface support. Separately identify engineering, configuration/programming, integrator-facility functional testing, and site acceptance testing for the two feeder relays, including secondary injection, trip simulation, and a written service report. - Reference equipment: The attached Siemens drawings document existing six-section, non-arc-resistant indoor 15 kV switchgear with a 12.47 kV operating system and 3000 A main bus; they do not specify additional standalone purchase quantities.
