Direct answer: A useful MV switchgear quotation needs more than voltage and quantity. Send the SLD, system data, functional units, protection requirements, site conditions, document scope, testing requirements and delivery destination so the manufacturer can prepare a technically comparable offer.
Technical Comparison
| Factor | Information Required |
|---|---|
| Electrical data | Nominal/highest voltage, frequency, rated current, fault level and duration |
| Configuration | Incoming, outgoing, transformer, metering, PT and bus-section functions |
| Protection | Relay, CT/VT, trip supply, control voltage and communication |
| Mechanical | Indoor/outdoor, cable entry, dimensions, IP requirement and access |
| Commercial input | Quantity, destination, project stage and required delivery basis |
Selection Checklist
- Confirm nominal and highest system voltage.
- Confirm rated current, short-circuit duty and duration.
- Map every feeder from the approved SLD.
- Review protection, metering and remote-control requirements.
- State altitude, temperature, humidity, pollution and installation conditions.
- Define drawings, testing, FAT and handover documents.
Qiangchi Product Options
Qiangchi supplies QCL-12 RMU, QCL-24 GIS, QCL-40.5 GIS, XGN15 air-insulated RMU and YB compact substation. Rated current options include 630A, 1250A, 2500A and 3150A where applicable to the selected product and approved configuration.
Engineering Workflow
- Receive SLD, BOQ and specification.

- Issue technical proposal and clarification list.
- Prepare project-specific GA and documents.
- Confirm inspection, routine tests and FAT scope.
- Complete export packing and shipment documents.
FAQ
Can I request a preliminary proposal?
Yes. Open items will be marked for technical confirmation.
Can the configuration be customized?
It can be evaluated against the SLD and actual product capability.
Are dimensions fixed?
No. Use the project-specific approved GA drawing.
What site data is required?
Temperature, altitude, humidity, pollution, corrosion, installation and seismic requirements where applicable.
Can FAT be witnessed?
The FAT and witness scope can be agreed during technical clarification.
What reduces quotation delays?
A clear SLD, system data, quantity, application, destination and document list.
Request a Project-Specific Proposal
Prepare a Complete Switchgear RFQ
Provide system voltage, rated current, frequency, short-circuit level and duration, functional units, quantity, application, SLD, BOQ, specification and required documents. This reduces technical clarification cycles and quotation risk.
