Single capacity row · unnamed 110 kV two-winding design
Yawei’s 110 kV two-winding, de-energized-tapping catalogue lists a 10,000 kVA row with 5.8 kW no-load loss and 45 kW load loss. It does not identify that row’s exact model code or load-loss reference temperature. A separate 220 kV test statement on the same page must not be used as test evidence for this 10 MVA record.

Extract the row and shared cells precisely
The source title identifies an oil-immersed, three-phase, two-winding transformer with de-energized regulation. The 10,000 kVA row publishes 0.46% no-load current and losses already in kW, so no W-to-kW conversion is needed. Preserve the source unit and ask for the test basis in the current proposal.
The table’s shared connection and impedance cells show YNd11 and 10.5%, with ±2 × 2.5% taps. Low-voltage choices include 6.3, 6.6 and 10.5 kV for this portion of the table. The high-voltage cell contains unclear additional text alongside 110; it is not repaired into extra voltage choices here. Request one explicit nameplate ratio and complete rating sheet.

| Capacity | 10,000 kVA | Catalogue row, exact model pending. |
| No-load / load loss | 5.8 / 45 kW | Reference temperature and current guarantee not supplied. |
| No-load current | 0.46% | Confirm measurement basis and tolerance. |
| Shared connection / impedance | YNd11 / 10.5% | Confirm against the selected design and study base. |
| Shared taps | ±2 × 2.5% | De-energized regulation, as source title states. |

Keep the 220 kV test claim outside this row
The surrounding introduction says an SSZ20-240000/220 product passed short-circuit withstand and routine/type tests. That is a named 240 MVA, 220 kV product reference, not the unnamed 10 MVA row reviewed here. Its statement cannot establish that this unit has passed the same tests.
The page also displays a company certificate gallery and general manufacturing information. Those materials have their own scopes. Request report identity, tested model, winding ratings, voltage, conditions and any design-applicability explanation relevant to the offered 10 MVA transformer. Separate corporate credentials, design evidence and the actual delivered unit’s routine-test record.
Agree which reports and witness points are required before factory release. A general “tested product” statement is insufficient to accept a different configuration; have the project reviewer evaluate the match and any limitations explicitly.
Identify the proposed unit
Obtain its exact model, complete rating and drawing revision.
Match each evidence item
Record the report’s tested design, rating, conditions and applicability to the proposed unit.
Agree release deliverables
Set guarantees, tolerances, routine tests, witness points and required signed reports.

Define the 10 MVA substation interfaces
Provide the system voltage, frequency, load duty, secondary-network requirement, protection interfaces and required taps to the maker. Ask for the selected impedance basis and tolerances, dielectric schedule, cooling ratings and temperature limits. Do not use the 10.5% shared cell alone to approve system compatibility or parallel operation.
No row-specific dimension, mass, oil quantity or terminal layout is established by this table. Request the installed and transport general arrangements, accessory removals, masses, lifting/centre-of-gravity information, foundation reactions, terminals and oil delivery condition. The generic photograph and compactness claim do not establish installation feasibility.
Supply site altitude, ambient and exposure, then request the matched cooling, accessories, alarms and maintenance instructions. The catalogue does not provide a complete site-specific operating envelope for this 10 MVA proposal.

Align the quotation with tests and transport
No verified current price or lead time is available. Obtain an itemized offer for the exact model and ratio, identifying oil, cooling/accessories, tests, packing, transport and site support. Require currency, trade term, date, validity and exclusions; do not use a price for the 220 kV reference or another capacity.
Ask for a schedule tied to an explicit starting event and separate design approval, manufacture, tests, release, dispatch and destination arrival. Name the documents needed at each gate and who approves electrical, mechanical and test evidence. A factory completion date does not establish site delivery or commissioning.

Buyer questions
Does the SSZ20-240000/220 test prove this row?
No. That is a different named 220 kV product. Request evidence whose scope applies to the offered 10 MVA design.
Is 45 kW directly comparable to another maker’s value?
Not without matching ratio, rating, cooling, reference temperature and test basis. The temperature is not supplied here.
Is the exact model already specified?
The reviewed table identifies a capacity row, not a model code. Ask the maker to identify the current proposed design.
Are the unclear HV choices corrected on this page?
No. The original ambiguity remains a supplier question; only a confirmed ratio should enter the order.
