110 kV RFQ Readiness Checker - Talite Transformer Co., Ltd

Electrical duty Define the network interface before discussing configuration or price.

1. Rated powerRequired MVA rating and any future loading expectation. 2. System voltageNominal system voltage and highest voltage for equipment. 3. Frequency and phases50/60 Hz and three-phase system confirmation. 4. Winding voltagesHV, LV and tertiary requirements where applicable. 5. Vector group and neutralConnection, phase displacement and grounding arrangement. 6. Impedance requirementTarget impedance and tolerance tied to the system study.

Voltage withstand and regulation Translate the grid duty into a project-specific insulation and control brief.

7. Withstand levelsPower-frequency and lightning-impulse withstand requirements. 8. Tap changerDETC or OLTC, regulation range, steps and control interface. 9. Short-circuit dutyAvailable fault level, duration and system-study reference. 10. Loss guaranteesNo-load, load and auxiliary loss evaluation basis.

Site and environment Factory design inputs and site-owner obligations need a clear boundary.

11. Site environmentIndoor/outdoor use, altitude, temperature and humidity. 12. Pollution and seismic dutyCreepage, contamination and seismic design criteria. 13. Cooling and sound limitsCooling stages plus factory and site acoustic acceptance. 14. Civil and fire interfacesFoundation, oil containment, clearances and fire strategy.

Accessories, testing and records State the evidence package as part of the supply scope.

15. Bushings and cable interfacesTerminal type, ratings, clearances and connection details. 16. Monitoring and protectionTemperature, gas, pressure and condition-monitoring requirements. 17. Applicable standardsContract edition, local rules and any purchaser specifications. 18. FAT and witness planRoutine, type or special tests plus hold and witness points. 19. Document packageDrawings, calculations, schedules, reports and O&M format.

Delivery and commercial boundary A comparable price needs a comparable responsibility split.

20. Transport envelopeRoute limits, shipping split, handling points and final location. 21. Field assembly and commissioning scopeSupplier supervision, assembly, oil treatment and energization support. 22. Schedule, warranty and serviceRequired dates, acceptance milestone, warranty basis and response expectations.
