Xinguang SC(B)10 1250 kVA catalogue row

The first performance table is headed SC(B)10. Its 1,250 kVA entry gives 2,088 W and 9,690 W, with the load-loss column explicitly referenced to 120 °C. The conversions are 2,088 ÷ 1,000 = 2.088 kW and 9,690 ÷ 1,000 = 9.690 kW. Preserve that temperature when comparing offers; it is not an allowable room temperature.

The shared high-voltage cell lists 6, 6.3, 6.6, 10, 10.5 and 11 kV; the secondary cell is 0.4 kV. Connection and tap cells also list options. Select one ratio, connection and tap arrangement and ask the maker to confirm the row’s relevance to the current design. Shared cells do not establish every possible combination.

The separate SC(B)11 1,250 kVA row has its own values. This page remains an SC(B)10 reference; it does not silently adopt the later table’s performance or comparative marketing claims.

Source notes: [P1]

If considering an upgrade from the existing 1,000 kVA reference, provide the actual load requirement and existing nameplate to the responsible engineer. Ask for review of downstream equipment, protection, voltage/connection, impedance and site interfaces. The higher kVA catalogue row is not by itself evidence of a compatible replacement or permission to increase the load.

The source’s neighbouring SC(B)10 rows list 1,000 kVA at 1.768/8.126 kW and 1,250 kVA at 2.088/9.690 kW, both with load loss referenced to 120 °C. Those are different capacities. Their absolute losses should not be treated as a matched efficiency ranking or an annual saving calculation. Use the same project duty when comparing candidate sizes and include all relevant design conditions.

Request the final installed and transport dimensions, masses, mounting pattern, terminals and service clearances for the selected 1,250 kVA unit. No capacity-specific layout is supplied in the reviewed text. Existing floor space or terminals cannot be assumed compatible from the product-family photograph.

1. Define the capacity need

   Return load duty, future requirement and the existing installation data for engineering review.

2. Review electrical interfaces

   Approve the selected rating, connection, taps, impedance and protection interfaces.

3. Release the room layout

   Use order-specific dimensions, terminals and ventilation instructions before civil or cable work.

Source notes: [P1]

The SC(B)10 description gives indoor operation, ambient no higher than 40 °C and altitude no higher than 1,000 m, with AN/AF cooling and enclosure choices. It describes temperature monitoring and fan/alarm/trip functions. Confirm the actual supplied controls, enclosure and rating under each cooling condition.

The original ventilation wording contains an unclear unit string. No airflow figure is transferred from it into this page. Ask the manufacturer for ventilation and heat-rejection requirements for the chosen duty, enclosure and cooling package; do not treat the sum of catalogue loss columns as a constant room heat load.

The high-voltage-coil narrative uses F-class wording while the technical description uses H-class wording. Resolve the complete insulation system and permitted temperature rise in the current rating sheet. A low-voltage foil-form winding description does not prove the conductor metal of either complete winding.

Source notes: [P1]

The source cites older standards. Request the applicable current project requirements and matched test scope for the offered unit rather than assuming present compliance or production availability from the historical catalogue. Require losses, reference temperature, dielectric/thermal guarantees, controller checks and installation instructions in the acceptance schedule.

No verified price or lead time was established. Ask for an itemized offer for the selected 1,250 kVA configuration, including enclosure, fans, temperature controller, tests, packing, transport and site support. Request dated currency, trade terms and validity. Name the schedule’s start event and separate drawing approval, manufacture, tests, dispatch and arrival.

Source notes: [P1]

Define the 1,250 kVA duty and any replacement/upgrade context.
