Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Distribution Transformers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This S11 three-phase oil-immersed distribution transformer is listed for power and distribution duties. The stated configuration has a rated capacity of 500 kVA and a high-voltage rating of 11 kV. Its documented construction includes a core-type silicon-steel core, two windings, and Class A insulation.
Cooling is identified as ONAN/ONAF in the basic specifications, while the broader product parameter table lists ONAN. Supported configuration details include 50/60 Hz frequency, a 60/65 K temperature-rise value, and lightning impulse withstand performance stated as being in accordance with the applicable IEC standard.
Reference standard IEC 60076 is listed. The winding material is offered as copper or aluminum, so the selected conductor must be defined in the purchase specification. Customization is stated as available, and the listed packaging method is a wooden package.
Procurement questions to confirm: Buyers should request a final datasheet and drawing for the exact ordered unit.
Confirm the primary and secondary rated voltages, vector group, impedance, tap range and tap-changer type, selected winding material, guaranteed losses, efficiency, enclosure or tank arrangement, accessories, fluid specification, protection devices, terminals, ambient conditions, altitude, noise limits, and required tests.
Also reconcile whether the required cooling designation is ONAN or ONAN/ONAF. The source listing references both oil-immersed and dry-type transformers, but the detailed S11 configuration is identified as oil-immersed;confirm the required transformer technology before ordering.
Certification scope, inspection documents, final dimensions, shipping weight, and the standards applying to the purchased configuration should also be verified in writing.
