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 3150 kVA cast resin dry-type transformer is configured for three-phase power and distribution duties. Its listed electrical ratings are 34.5 kV on the high-voltage side and 0.415 kV on the low-voltage side, with 50/60 Hz operation.
The transformer uses a two-winding, core-type design with silicon-steel core material and either copper or aluminum winding conductors. The stated configuration includes a Dyn11 vector group, 4–8% impedance, a tapping range of +2 × 2.5% and −2 × 2.5%, Class H insulation, and a 125 K temperature rise.
Cooling is identified as AN/AF, and IP20 or IP23 enclosures are listed. Fans and an enclosure are available among the accessories. The reference standard is IEC 60076-11, while impulse and AC withstand levels are specified as being according to the applicable IEC standard.
Customization is available for capacity, high- and low-voltage ratings, impedance, vector group, and insulation class.
This allows the final transformer schedule to be aligned with the purchaser’s network design, but the ordered configuration should be documented explicitly rather than inferred from the available options.
Before procurement, the buyer should confirm the required capacity—particularly whether the project needs the detailed 3150 kVA configuration or another customized rating—the exact system voltages and frequency, conductor material, tap arrangement, impedance tolerance, cooling mode, enclosure protection, installation environment, and accessory package.
The buyer should also request the certificates and test reports applicable to the exact offered model and confirm the required routine, type, and special tests.
Final dimensions, total mass, terminal arrangement, losses, sound level, short-circuit withstand requirements, and approved drawings are not established by the supplied technical details and should be agreed before manufacture.
