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 oil-immersed step-down distribution transformer is offered for three-phase power-distribution applications. The listed product range includes 250 kVA and 1000 kVA configurations, 10 kV and 13.8 kV input-voltage options, and selectable output voltages of 200 V, 208 V, 220 V, 380 V, 400 V, or 415 V.
The transformer is identified as a two-winding, core-type design with 50 Hz and 60 Hz frequency options. The described construction uses a fully sealed corrugated oil tank intended to prevent the transformer oil from .
For the listed 10 kV family, the supplied performance table identifies Dyn11, Yzn11, and Yyn0 connection-group options across the range, although the applicable group depends on rated capacity.
At 250 kVA, the table lists 230 W no-load loss, 2300/2195 W load loss at 75°C, 0.9% no-load current, and 4.0% short-circuit impedance. At 1000 kVA, it lists 665 W no-load loss, 7415 W load loss at 75°C, 0.6% no-load current, and 4.5% short-circuit impedance.
These figures should be treated as configuration-specific rather than universal values for every offered voltage arrangement. Customization is listed as available, including OEM and ODM service.
Copper and aluminum are both named in the product information, so the required winding or conductor construction must be defined in the purchase specification rather than assumed. A wooden transport case and standard specification are listed.
Procurement questions to confirm before ordering: Ask for a configuration-specific datasheet covering rated capacity, exact high- and low-voltage ratio, tapping range, vector group, frequency, conductor material, insulation system, cooling designation, temperature-rise limits, impedance, and guaranteed losses.
Confirm whether the requested 13.8 kV arrangement carries the same ratings shown in the 10 kV performance table.
Buyers should also request applicable drawings, terminal arrangement, overall dimensions, total and oil weights, accessories, protection devices, test schedule, inspection criteria, installation conditions, and document package.
Confirm the exact certification scope and edition required by the project, as well as quantity, production schedule, packing, shipping responsibilities, commissioning support, and warranty terms in the final contract.
