Direct Recommendation
An 11kV compact-substation RFQ should define the MV source and feeder duty, transformer capacity and LV system, protection and metering, enclosure arrangement, cable entry, site environment, auxiliary supply, tests, drawings, and package boundary.
For commercial developments, industrial distribution, utilities, infrastructure, and replacement packages, the useful deliverable is not another broad definition. It is a marked specification, a deviation list, and enough project information for a supplier to identify the correct equipment family. Start from Compact Substations; those pages define the current public Jinxing product scope.
Decision Summary
- Buyer intent: RFQ checklist.
- Project context: commercial developments, industrial distribution, utilities, infrastructure, and replacement packages.
- First evidence to prepare: the approved single-line diagram plus the equipment data sheet, load schedule, or feeder schedule that applies to this request.
- Expected supplier response: a model-family match, marked technical exceptions, applicable evidence, missing inputs, and a defined quotation boundary.
Product Scope Relevant to 11kv compact substation
The rows below are limited to products already published on the Jinxing website. Use them to identify the relevant family and voltage class, then verify the actual rating, arrangement, components, tests, and documents against the project specification.
| Jinxing product | Public voltage scope | Typical website application | Use this page to |
|---|---|---|---|
| American Compact Substation | 10kV / 11kV / 20kV / 35kV project classes | Outdoor utility, commercial, and industrial distribution | Check the model family and send project-specific requirements |
| European Compact Substation | 10kV / 11kV / 20kV / 35kV project classes | Commercial buildings, infrastructure, and industrial parks | Check the model family and send project-specific requirements |
| YB Prefabricated Substation | Project-based MV/LV configuration | Factory distribution, parks, substations, and municipal projects | Check the model family and send project-specific requirements |
Quotation-ready specification structure
A useful RFQ defines the system, equipment duty, physical interfaces, verification scope, and commercial boundary in one package. For 11kv compact substation, the review should produce the following evidence or decision at each stage.
| Review area | Question to close | Evidence or output |
|---|---|---|
| System definition | Single-line diagram, source, load, fault level, earthing, and operating philosophy | Approved electrical design basis |
| Equipment schedule | Ratings, feeder or transformer duties, quantities, spares, and future provision | Data sheet and equipment list |
| Interfaces | Cable, busduct, control, communication, civil, room, enclosure, and environmental constraints | Interface and layout drawings |
| Acceptance and delivery | Standards, tests, documents, inspection, packing, destination, and target date | Document and commercial schedule |
Stop and clarify the offer when any of these red flags appear:
- Requesting a price from only a product name and voltage.
- Missing fault level, feeder schedule, or installation environment.
- Not defining drawings, tests, packing, and delivery boundary.
Six Technical Decisions to Record
These six decisions are selected for the rfq checklist behind 11kv compact substation.
| Decision | Why it changes the offer | Required project input |
|---|---|---|
| Package boundary | Define which transformer, MV, LV, enclosure, protection, metering, auxiliaries, and site works are included in the supplier scope. | Record the project value or mark it as an open package boundary clarification |
| Voltage class and ratio | Match the upstream supply, downstream system, insulation coordination, and local utility requirements. | Record the project value or mark it as an open voltage class and ratio clarification |
| Capacity and load profile | Use connected load, demand, motor starting, harmonics, redundancy, and future expansion rather than nameplate totals alone. | Record the project value or mark it as an open capacity and load profile clarification |
| Feeder function | Separate incomer, outgoing, transformer feeder, motor feeder, bus coupler, metering, and compensation duties. | Record the project value or mark it as an open feeder function clarification |
| Protection and coordination | Confirm breaker or fuse duty, relay functions, CT/VT inputs, selectivity, earthing, and upstream/downstream coordination. | Record the project value or mark it as an open protection and coordination clarification |
| Drawings and test documents | List required GA drawings, single-line diagrams, nameplate data, routine tests, report references, certificates, and shipping documents. | Record the project value or mark it as an open drawings and test documents clarification |
Engineering Review Notes
1. Package boundary
Define which transformer, MV, LV, enclosure, protection, metering, auxiliaries, and site works are included in the supplier scope. In the context of commercial developments, industrial distribution, utilities, infrastructure, and replacement packages, write this decision into the 11kv compact substation data sheet and ask the supplier to mark any deviation. The review output should be a value, drawing reference, calculation input, or explicit technical clarification rather than an unrecorded assumption.
2. Voltage class and ratio
Match the upstream supply, downstream system, insulation coordination, and local utility requirements. In the context of commercial developments, industrial distribution, utilities, infrastructure, and replacement packages, write this decision into the 11kv compact substation data sheet and ask the supplier to mark any deviation. The review output should be a value, drawing reference, calculation input, or explicit technical clarification rather than an unrecorded assumption.
3. Capacity and load profile

6. Drawings and test documents
List required GA drawings, single-line diagrams, nameplate data, routine tests, report references, certificates, and shipping documents. In the context of commercial developments, industrial distribution, utilities, infrastructure, and replacement packages, write this decision into the 11kv compact substation data sheet and ask the supplier to mark any deviation.

Applicable Evidence and Its Limits
The Jinxing website references GB/T 17467, IEC 62271 reference support for the relevant product families. These are standards families or project references to discuss. They are not a statement that every rating, arrangement, component, or optional test is automatically covered by the same document.
Public evidence available for early review includes:
For this rfq checklist, request a document register that ties each report, certificate, drawing, and routine test to the quoted model or project. Sample evidence supports early qualification; final acceptance records must match the approved configuration and contractual inspection plan.
RFQ Package for 11kv compact substation
Use this product-specific structure instead of sending only a keyword, catalogue request, or target price.
