Original product description
Product overview This SCB-series dry-type power transformer is offered for three-phase power applications in 400 kVA and 500 kVA configurations. The advertised configuration uses an 11 kV input and 480 V output.
The listing identifies a core-type, two-winding construction, dry-type cooling, a layer-coil core shape, and support for 50 Hz or 60 Hz systems. Copper and aluminum are both listed as core-material options, so the selected construction should be documented for each order.
Published performance data For the 6–11 kV / 0.4 kV table, the published 400 kVA values are 1.0% no-load current, 980 W no-load loss, 3,750 W load loss at B (100°C), 3,990 W at F (120°C), and 4,280 W at H (145°C), with 4.0% short-circuit impedance.
The corresponding 500 kVA values are 1.0%, 1,160 W, 4,590 W, 4,880 W, and 5,230 W, with 4.0% short-circuit impedance.
These table values reference a 0.4 kV low-voltage configuration, while the advertised product configuration states 480 V;buyers should therefore obtain performance data for the exact 11 kV / 480 V unit being quoted.
Configuration information The listing identifies Yyn0 and Dyn11 connection-group symbols for the referenced series and shows high-voltage tapping of ±2 × 2.5% in the 6–11 kV table. It also lists 10.5 kV, 11 kV, 12.47 kV, and 13.2 kV input-voltage options, plus 415 V and 480 V output options.
Customization is stated to be available, and the transport package is listed as a wooden case.
Buyer confirmation before procurement Confirm the final rated capacity, exact primary and secondary voltages, frequency, winding or core-material selection, connection group, tapping arrangement, insulation and temperature class, loss values, impedance, enclosure configuration, overall dimensions, weight, terminal arrangement, installation environment, and required accessories.
Also request the exact technical datasheet and routine test documentation for the ordered configuration. Warranty, lead time, freight, commissioning scope, and after-sales terms are not defined in the and should be agreed in the purchase contract.
