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/S13 oil-immersed transformer is intended for three-phase power distribution, including photovoltaic substation projects. The listed design is a core-type, two-winding transformer with oil cooling.
Available configuration information includes copper or aluminum coils, a 380 V stated output, and selectable high-voltage arrangements. The supplied performance table covers rated capacities from 30 kVA to 3150 kVA and lists Dyn11, Yyn0, and Yzn11 vector-group options. A tapping range of ±2 × 2.5% is also shown.
Supported configuration details The transformer is described as customizable for project voltage, capacity, tap-changer, bushing, protection-accessory, and color requirements. The listing identifies 6 kV, 10 kV, and 35 kV input options, while the product identity also references 11 kV and 33 kV systems.
Cooling references include ONAN and ONAF. Individual table values are provided for no-load loss, load loss at 75°C, no-load current, impedance voltage, and total weight across multiple capacity ratings.
Procurement questions to confirm Before specifying or ordering, the buyer should confirm the exact primary and secondary voltages, rated capacity, system frequency, vector group, impedance, tapping method and range, winding conductor, cooling arrangement, insulation level, temperature-rise requirement, and required protection accessories.
The 11 kV and 33 kV should be reconciled with the separa ecause performance and weight vary by capacity.
Confirm the applicable test standard, required certificates, enclosure or ingress-protection requirement, installation environment, dimensional drawing, terminal arrangement, oil specification, and approved single-line diagram before production.
