Historical family catalogue · SC(B)10 and SC(B)11 kept separate
Xinguang’s combined SCB10(11) page contains two construction descriptions and two performance tables. It is best read as a catalogue navigator: choose the design and capacity first, preserve the 120 °C load-loss reference, and resolve source inconsistencies before requesting a current offer. It is not one universal specification for the entire family.

SCB10 / SCB11- Design references
- SC(B)10 and SC(B)11
- Narrative capacity range
- 80–2,500 kVA
- Performance tables
- Include separate 30 and 50 kVA rows
- Load-loss reference
- 120 °C in both table headings
Keep narrative ranges and table coverage distinct
Both technical descriptions state 80–2,500 kVA, while the performance tables also include 30 and 50 kVA entries. This is a source-scope difference. The family record preserves the stated narrative range rather than silently expanding it; if a lower capacity is needed, ask the manufacturer whether it is currently offered and which design schedule applies.
The SC(B)10 description centres on a 10 kV class, with several HV choices in its table. The SC(B)11 narrative additionally lists 6, 10, 20 and 35 kV classes, while its displayed loss table has a narrower set of shared voltage choices. Do not apply that loss table indiscriminately to a 20 or 35 kV design. Obtain the configuration-specific schedule.

Use paired rows as historical references
The examples below retain the design name and rating. All load-loss values come from columns headed 120 °C. Each watt value is divided by 1,000 for kW, for example SC(B)11 1,250 kVA: 1,885 W = 1.885 kW and 9,210 W = 9.210 kW. The figures are catalogue references, not fresh factory guarantees.
At a given capacity the tables publish different loss values, but a current purchase still needs the same ratio, taps, cooling, temperature and agreed tolerances. Do not use these examples to assert a universal saving across all capacities or as evidence of current stock.

Resolve conflicts instead of silently repairing the source
The SC(B)10 high-voltage-coil narrative refers to F-class insulation, while its technical description gives H-class thermal values. In the SC(B)11 prose, a temperature-rise figure differs from the technical list. Neither discrepancy is resolved here by choosing the more favourable statement; ask for the complete insulation system and thermal guarantees for the selected design.
The SC(B)11 1,600 kVA load-loss cell displays an anomalous value relative to neighbouring entries. It is excluded from the comparison examples. No replacement number is inferred or “corrected” into a specification. Request a signed current schedule if this capacity is required.
The ventilation wording includes an unclear unit string, and noise/partial-discharge comparative statements do not provide a complete selected-unit test basis. Keep these as unresolved evidence questions. The older standards named in the page are historical references rather than a present compliance conclusion.

Choose enclosure, cooling and controls as one package
The page describes AN/AF cooling, open or enclosed installation and IP00/IP20/IP23 options, with temperature monitoring and fan/alarm/trip functions. These choices are not one standard bill of materials. Specify the supplied enclosure, continuous ratings, controls, terminals and accessory responsibilities together.
The descriptions also discuss indoor ambient no higher than 40 °C and altitude no higher than 1,000 m, while separate enclosure wording discusses outdoor use. Do not infer that selecting an enclosure automatically qualifies every design for every outdoor exposure. Give the site conditions and obtain an explicit installation proposal with ventilation, clearances and maintenance instructions.
Request final drawings and masses for the chosen capacity and package. Construction descriptions and broad application lists do not establish the offered conductor materials, a fixed footprint or suitability for a particular high-rise, tunnel or other special location.
Source notes: [P1]
Request one current design against a clear requirement
Identify SC(B)10, SC(B)11 or the manufacturer’s current alternative, then ask for a complete model/rating sheet and matched test scope. Use that offer to resolve the historical catalogue gaps rather than blending the two descriptions. Agree losses, temperatures, insulation, dielectric requirements, controls and release documents.
No verified price or lead time is available. Request a dated quotation for the selected design and supplied package, with currency, trade terms, validity and separate accessories/tests/packing/transport costs. Name the event starting the schedule and separate drawing approval, manufacture, factory tests, dispatch and destination arrival.
Select the catalogue identity
Name the design and capacity, and state which historical values are reference only.
Resolve the open fields
Obtain current ratio, thermal/insulation, losses, cooling and installation data.
Approve the matched offer
Align guarantees, reports, drawings, supply scope and commercial milestones before ordering.

Buyer questions
Does the combined title mean one shared specification?
No. The page contains distinct SC(B)10 and SC(B)11 descriptions and tables.
Is the family range 30–2,500 kVA?
The narrative says 80–2,500 kVA, while tables include smaller entries. Confirm current availability rather than silently changing the range.
Can the table guarantee a 35 kV SC(B)11 design?
The narrative and displayed table have different voltage coverage. Obtain the 35 kV configuration’s own schedule.
Did this page correct the anomalous 1,600 kVA cell?
No. The ambiguous cell is excluded from comparison and requires a current supplier schedule.
Are the paired figures a guaranteed saving?
They are historical references. A current comparison needs matched design conditions and project duty.
