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 pad-mounted oil-immersed transformer is offered for three-phase power distribution. The listed configuration is an 800 kVA, two-winding, core-type transformer with a 0.4 kV low-voltage side, model S13, and support for 50 Hz or 60 Hz power-frequency systems.
The specification identifies an iron core and copper winding. A fully sealed, hermetic tank design is described, together with a corrosion-resistant tank intended for high-humidity and high-salt-spray environments. The stated operating ambient temperature range is -20°C to +40°C.
Listed technical characteristics include partial discharge below 5 pC, resistance to an impact of 2.5 times rated current, and an anti-seismic design rated for level-8 earthquake intensity.
The also identifies grain-oriented silicon steel for the core and cites IEC 60076 and GB/T 6451 as design and manufacturing standards. Customization is listed as available.
Important configuration note: the product title identifies a 27.5/0.4 kV transformer, while the attribute table lists the high-voltage side as 33 kV and the low-voltage side as 0.4 kV. These references should not be treated as interchangeable.
Before procurement, the buyer should obtain a unit-specific technical schedule confirming the required primary voltage, tapping arrangement, insulation levels, vector group, impedance, losses, temperature rise, cooling designation, enclosure arrangement, and terminal interfaces.
Buyers should also confirm whether every stated feature, standard, test, and certification applies to the exact 800 kVA unit being quoted. Request the final outline drawing, nameplate schedule, routine and type-test documentation, oil specification, accessory list, installation requirements, and packing dimensions.
Site altitude, ambient conditions, seismic requirements, corrosion exposure, protection coordination, cable entry, grounding, and compatibility with upstream and downstream equipment should be reviewed before approval.
