Buyer's Digest

Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Pad Mounted Transformers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

This 750 kVA three-phase pad-mounted transformer is configured for stepping a 13.8 kV primary supply down to a 480Y/277 V secondary. It is intended for power distribution projects, including commercial facilities, urban distribution networks, industrial parks, and solar-power installations.

The listed design uses a two-winding, core-type transformer arrangement with ONAN cooling and 100% copper winding. Published electrical parameters include 60 Hz frequency, 2%–5% impedance voltage, and an off-circuit tap changer with a regulation range of ±2 × 2.5%. Listed vector-group options are Dyn11 and Yyn0.

The stated operating envelope is an ambient temperature range of -30°C to +40°C and a maximum altitude of 1,000 m. The product is listed as UL certified, with additional certifications or standards identified as ISO 9001, CCC, CE, and IEC 60076.

Buyers should request the applicable certificate, test report, and nameplate schedule for the exact 750 kVA, 13.8 kV/480Y/277 V configuration before approval, because the broader product listing includes customized voltage, capacity, winding-material, cooling, and compliance options.

Procurement review should confirm the required vector group, impedance, tap positions, insulation and protection arrangement, enclosure details, accessories, losses or efficiency values, and applicable utility requirements.

Buyers should also confirm whether ONAN alone or an ONAN/ONAF arrangement applies to the ordered unit. Final drawings should document terminal configuration, overall dimensions, gross weight, site elevation, ambient conditions, and foundation or cable-entry requirements.

The listed shipping package is a customizable wooden case;quoted package dimensions and weight should be verified against the approved production design.
