Original product description
This 250 kVA cast resin dry-type transformer is offered as a three-phase step-down unit for power and distribution duties.
The listed electrical configuration includes 10, 11, 22, or 35 kV high-voltage options, a 0.4 kV low-voltage rating, 50/60 Hz operation, a ±2 × 2.5% tapping range, 4% impedance voltage, and Yyn0 or Dyn11 connection groups. Aluminum and copper winding options are listed.
The transformer uses an epoxy-cast dry-type structure with core-type construction. Listed configuration options include ANAF cooling, Class F insulation, a 100 K temperature rise, and IP00, IP20, or IP30 protection levels. The stated installation altitude is no more than 1,000 m.
The broader listed series covers nominal capacities from 30 kVA to 2,500 kVA, allowing related ratings to be considered where the 250 kVA configuration does not match the project load. Several values in the available product information refer to different models or configurations.
In particular, one parameter table identifies model SCB10-50/10 and a 50 kVA rated capacity, while the product identity states 250 kVA. Listed dimensions and weights also vary.
Buyers should therefore obtain a unit-specific datasheet and approved drawing showing the exact 250 kVA rating, voltage ratio, winding conductor, connection group, enclosure, cooling arrangement, losses, dimensions, and weight before purchase.
For procurement, confirm the required primary and secondary voltages, system frequency, vector group, tapping arrangement, short-circuit impedance, installation environment, altitude, enclosure rating, cooling mode, and applicable test standard.
Certification documents, routine and type-test reports, terminal arrangement, accessories, shipping package, production schedule, and written warranty terms should also be reviewed for the exact offered unit.
