Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Dry Type Transformers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The SCB18 is a three-phase, two-winding, core-type dry transformer intended for power and distribution service. The supplied specifications identify a 20 kV rated primary, 0.4 kV output, 50/60 Hz power-frequency operation, copper windings, EI core construction, and a Dyn11 vector group.
The windings are described as epoxy-resin cast coils, and the listed cooling method is AN/AF. An off-circuit tap changer is specified with either ±5% or ±2 × 2.5% tapping.
The listed capacity range is 30–3150 kVA, although the detailed description separa;buyers should therefore confirm that the required rating is available and obtain the exact model schedule before ordering. Impedance is described as 6% for models from 30 to 1600 kVA and 8% for ratings of 2000 kVA and above.
For the 1000 kVA model, the supplied data lists 1.40 kW no-load loss and load loss of 8.80 kW at F-class 120°C or 9.36 kW at H-class 145°C, with 6% short-circuit impedance. These figures apply only to the stated 1000 kVA configuration and should not be extrapolated to other ratings.
The product information associates the series with IEC 60076, IEEE, ANSI, and DOE standards and separa ot provided, buyers should request model-specific documentary evidence rather than assume that every configuration carries every listed approval.
Before procurement, confirm the required kVA rating, primary and secondary voltages, tap range, frequency, vector group, cooling arrangement, impedance, insulation temperature class, loss limits, enclosure or ingress-protection requirement, ambient and installation conditions, accessories, monitoring requirements, dimensions, weight, terminal arrangement, and applicable testing.
The listing indicates that customization is available, but the exact configurable options must be agreed for the selected model.
