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 SZ11 three-phase oil-immersed transformer is presented for power and distribution duties. The listed construction includes a core-type design, separated windings, three coils, and an oil-immersed cooling method. Rated frequency options are 50 Hz and 60 Hz, while the stated capacity range is 30–10,000 kVA.

For the documented 10,000 kVA configuration, the supplied data states a Yd11 connection group, 7.70 kW no-load loss, 47.7 kW load loss at 75°C, 0.55% no-load current, 5.5% impedance voltage, and overall dimensions of 2850 × 2880 × 3265 mm.

The description also identifies a fully sealed corrugated-tank design without an oil conservator and lists pressure-relief and gas-relay protection. The voltage information requires technical clarification.

The product title identifies a 110 kV transformer, while the basic specification states a service-voltage range of 0–35 kV and the narrative references a standard 10 kV/0.4 kV transformation.

Buyers should therefore treat the exact primary and secondary voltage ratings as configuration-dependent until confirmed in an approved datasheet. Customization is stated as available for rated capacity, input and output voltage, physical size, protective coating, and selected environmental requirements.

OEM service is also offered. The listed transport package is a wooden box;however, the published package dimensions and gross weight differ from the separate overall transformer dimensions and should be verified for the ordered configuration.

Before purchase, request a configuration-specific technical schedule covering rated voltages, tap range, vector group, frequency, losses, impedance, insulation levels, cooling arrangement, accessories, environmental limits, and final dimensions and mass.

Buyers should also confirm which standards and certificates apply to the exact unit, obtain the relevant test reports and wiring diagram, and agree on inspection, documentation, packing, delivery, commissioning support, and warranty terms in the purchase contract.

Buyer tips

  • State quantity range and split-delivery needs before price comparison.
  • Add certification, material or inspection standards when they affect acceptance.
  • For time-sensitive projects, include target arrival date and destination.
  • For special applications, describe operating condition, installation environment and duty cycle.

FAQ

What should buyers confirm first?

Confirm application, specification, quantity, destination and lead-time requirements before comparing offers.

Can buyers inquire when specs are incomplete?

Yes. Add model, material, size, use case and inspection needs in the RFQ to make replies comparable.

How should this listing be evaluated?

Check title, category, specifications and related keywords against the actual sourcing requirement.
