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
This 1250 kVA three-phase dry-type transformer is specified for industrial step-down service from 20 kV to 0.4 kV. The listed model is SCB11, with a core-type construction, separated windings, three coils, and ANAF cooling. Rated-frequency information includes both 50 Hz and 60 Hz.
The states that core components are vacuum-cast with epoxy resin and have self-extinguishing properties. It also describes moisture-resistant operation in environments with up to 100% humidity and says the unit can return to service after shutdown without pre-drying.
In forced-air cooling mode, output capacity is stated to increase by up to 50% for emergency overload operation. The supplied information also lists Dyn11 or Yyn0 connection groups, high-voltage tap options of ±5% or ±2 × 2.5%, and wooden-case transport packaging.
The configuration is described as customizable, including adjustments to power, dimensions, input and output voltage, protection level, and working-environment requirements.
Procurement note: several entries in the supplied technical information describe a broader transformer range rather than an unambiguous final configuration for this specific 1250 kVA unit.
Before ordering, the buyer should obtain a project-specific datasheet confirming the 20 kV primary, 0.4 kV secondary, frequency, connection group, tap range, cooling duty, insulation level, enclosure or IP rating, and guaranteed loss and noise values.
Buyers should also confirm whether the stated packed dimensions and gross weight apply to the selected configuration. For technical approval, request the final outline drawing, wiring diagram, terminal arrangement, routine test report, product certificates, installation manual, and declared standards.
Confirm site altitude, ambient temperature, humidity, indoor or outdoor placement, ventilation, harmonic loading, short-circuit requirements, seismic conditions, and any enclosure or fire-safety requirements before final selection.
