Xinguang SC(B)10 800 kVA catalogue row

The SC(B)10 performance table lists 1,520 W and 6,953 W for 800 kVA. Divide each by 1,000 to obtain 1.520 and 6.953 kW. The load-loss heading states 120 °C, which must travel with the converted number. A loss copied without its design reference or temperature is an incomplete comparison entry.

The same row shows 1.36% no-load current and 54 dB noise. No complete measurement arrangement or current guarantee is established by those catalogue cells. Ask for the proposed unit’s test conditions, noise quantity/method and tolerances before using the noise number in a room or tender assessment.

The table shares HV choices 6/6.3/6.6/10/10.5/11 kV and LV 0.4 kV, with connection and tap options. The separate SC(B)11 table below it contains another 800 kVA design reference. Keep that later row separate; this page does not select its values for the SC(B)10 unit.

Source notes: [P1]

Give the supplier the existing nameplate, single-line diagram, primary and secondary interfaces, taps, connection and protection requirements. Ask the responsible engineer to review the selected ratio and impedance, compatibility and fault/protection implications. An 800 kVA label alone is insufficient to establish a drop-in replacement.

Attach the existing footprint, mounting, terminal locations, cable/bus approach, access route and room clearances. Ask for final installed and shipping dimensions, mass, lifting instructions and terminal drawings for the actual offer. The source’s compactness statements and product photograph do not provide an 800 kVA dimensional schedule.

The manufacturer’s description allows open or enclosed arrangements and natural or forced-air cooling. Specify the required enclosure, cooling duty and controller/fan/alarms/trip package. A fan option must come with an explicit rating and operating conditions; the page’s general increased-capacity statement does not define a continuous overload allowance.

The SC(B)10 narrative uses F-class wording for the high-voltage winding, while the technical description states H-class values. Ask for the complete insulation system and thermal limits of the proposed replacement. The foil-form low-voltage description also leaves conductor materials open; do not assign copper to both windings without confirmation.

1. Capture the existing installation

   Collect nameplate, diagrams, connections, protection and mechanical interfaces.

2. Approve the current proposal

   Compare the proposed rating sheet, cooling/insulation and drawings against the installation requirements.

3. Freeze the acceptance basis

   Agree numerical guarantees, test conditions and document identity before manufacture or release.

The catalogue’s SC(B)10 conditions are indoor use, ambient no higher than 40 °C and altitude no higher than 1,000 m. Provide actual room ventilation, contamination and condensation conditions; broad humidity and application statements are not installation-specific approval. Obtain instructions for heat rejection, clearances, controls and maintenance under the chosen package.

The page cites older standards and does not establish current availability or compliance. Request the applicable project requirements and exact proposed model. Match factory reports, ratings, test temperatures and drawing revisions to that unit, and separate design evidence from the actual delivered unit’s routine-test records.

No verified purchase price or lead time is available. Obtain an itemized quotation including enclosure, fans/controller, tests, packing, transport and site support, with currency, trade terms and dated validity. For a replacement shutdown, agree drawing approval, factory release, dispatch and arrival separately; define the lead-time start and required handover documents instead of assuming a factory date covers the site programme.

Provide existing 800 kVA nameplate, diagrams and replacement scope.
