Direct Recommendation
Oil-immersed transformer installation should coordinate foundation and oil containment, lifting, clearances, earthing, bushings and cable connections, oil and accessory checks, protection and alarms, cooling equipment, fire provisions, pre-energization inspection, and site acceptance records.
For outdoor substations, industrial sites, utility feeders, commercial projects, and replacements, 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 Oil-Immersed Transformers; those pages define the current public Jinxing product scope.
Decision Summary
- Buyer intent: Installation checklist.
- Project context: outdoor substations, industrial sites, utility feeders, commercial projects, and replacements.
- 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 oil immersed transformer installation
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 |
|---|---|---|---|
| 10kV Oil-Immersed Transformer | 10kV / 11kV class | Commercial, residential, rural grid, industrial | Check the model family and send project-specific requirements |
| 20kV Oil-Immersed Transformer | 20kV class | Utility distribution and industrial systems | Check the model family and send project-specific requirements |
| 35kV Oil-Immersed Transformer | 35kV class | Medium-voltage distribution and substations | Check the model family and send project-specific requirements |
| 110kV Oil-Immersed Transformer | 110kV class | Grid and large industrial projects | Check the model family and send project-specific requirements |
Site and lifecycle control points
Installation and maintenance work must follow the approved drawings, manuals, safety procedure, and local rules for the exact equipment. For oil immersed transformer installation, the review should produce the following evidence or decision at each stage.
| Review area | Question to close | Evidence or output |
|---|---|---|
| Site readiness | Foundation, access, clearances, ventilation, containment, trench, and lifting route | Approved civil and equipment drawings |
| Assembly | Accessories, conductors, torque, earthing, control wiring, and labels | Installation checklist and supplier instructions |
| Functional verification | Protection, alarms, interlocks, indications, mechanisms, and communication | Recorded test results and settings |
| Ongoing maintenance | Inspection interval, cleaning, thermal checks, operation counts, spares, and records | Site maintenance plan and equipment history |
Stop and clarify the offer when any of these red flags appear:
- Changing the layout without checking cable and maintenance access.
- Treating visual inspection as complete commissioning.
- Performing work without isolation, approved procedures, or recorded results.
Six Technical Decisions to Record
These six decisions are selected for the installation checklist behind oil immersed transformer installation.
| Decision | Why it changes the offer | Required project input |
|---|---|---|
| Installation environment | Indoor or outdoor location, altitude, humidity, salt, dust, corrosion, and ambient temperature can change the enclosure and accessory scope. | Record the project value or mark it as an open installation environment clarification |
| Panel or package layout | Align feeder sequence, busbar arrangement, metering, cable rooms, ventilation, transport sections, and future spare ways. | Record the project value or mark it as an open panel or package layout clarification |
| Cable entry and termination | Coordinate cable size, bend radius, entry direction, termination height, gland plates, phase spacing, and site trench layout. | Record the project value or mark it as an open cable entry and termination 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 |
| Inspection and acceptance | Agree document review, factory inspection, routine tests, witness points, packing checks, and site acceptance responsibilities. | Record the project value or mark it as an open inspection and acceptance 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. Installation environment
Indoor or outdoor location, altitude, humidity, salt, dust, corrosion, and ambient temperature can change the enclosure and accessory scope. In the context of outdoor substations, industrial sites, utility feeders, commercial projects, and replacements, write this decision into the oil immersed transformer installation 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. Panel or package layout
Align feeder sequence, busbar arrangement, metering, cable rooms, ventilation, transport sections, and future spare ways. In the context of outdoor substations, industrial sites, utility feeders, commercial projects, and replacements, write this decision into the oil immersed transformer installation 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. Cable entry and termination

Applicable Evidence and Its Limits
The Jinxing website references GB 1094, GB/T 6451, IEC 60076 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 installation 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.
