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 S13 series unit is a three-phase, two-winding, oil-immersed distribution transformer intended for power-frequency service. The listed design is core-type and uses a laminated silicon-steel core.
Available configuration details include 6.6 kV and 11 kV voltage classes, 50/60 Hz frequency, copper or aluminum conductor options, and either an on-load or off-load tap changer. The transformer uses a corrugated, hermetically sealed tank intended to limit .
Transformer oil provides cooling for the windings and core while contributing to the insulation system. A pressure-relief device is described for releasing excessive internal pressure. Outdoor construction and customizable gray, green, or other requested colors are listed.
Connection-group options are stated as Yyn0 and Dyn11, while the broader listing also references Y, Yn0, D, and Yn11 arrangements. IEC 60076 and GB 1094 are identified as available standards.
Because the supplied performance table is labeled for S11-M models rather than the titled S13 series, buyers should request the exact S13 datasheet and guaranteed values for the selected rating instead of applying the S11-M figures automatically.
Before procurement, confirm rated power, exact primary and secondary voltages, vector group, conductor material, tap-changer type and range, impedance, no-load and load losses, temperature-rise limits, cooling designation, insulation levels, accessories, enclosure details, overall dimensions, total and oil weights, and installation environment.
Also request the applicable test plan, routine test reports, drawings, nameplate schedule, packing method, delivery schedule, and written warranty terms for the offered configuration.
