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
The Hairui S11 is a three-phase, core-type oil-immersed transformer intended for power and distribution service. The listed configuration uses separated windings, three coils and a fully sealed corrugated tank. The tank design eliminates the oil conservator and isolates the transformer oil from air and moisture.
Available parameters are stated as 30 to 10,000 kVA rated capacity, 0 to 35 kV service voltage, and 50 or 60 Hz frequency. Capacity, voltage, dimensions, color and protective coating can be customized.
A 10,000 kVA reference configuration is documented with a Yd11 connection group, 7.70 kW no-load loss, 47.7 kW load loss at 75°C, 0.55% no-load current and 5.5% impedance voltage. Its stated overall dimensions are 2850 × 2880 × 3265 mm. These reference values should not be assumed for other ratings or configurations.
Supported construction and production features include vacuum drying and oil filling, balanced winding ampere-turn distribution, and structural fastening intended to improve mechanical and short-circuit resistance. Listed protection options include a pressure-relief valve and gas relay.
The transformer is presented for grid distribution, industrial and mining power distribution, infrastructure projects, renewable-energy step-up or grid-connection duties, and integration into prefabricated substations.
Suitability for any specific installation remains dependent on the selected electrical and environmental specification.
Buyer confirmation before ordering: request the final datasheet and nameplate schedule for the required primary and secondary voltages, capacity, vector group, tapping arrangement, frequency and impedance. Confirm whether the order is based on the stated 10 kV/0.4 kV configuration or another customized voltage.
Verify guaranteed no-load and load losses for the selected rating, applicable efficiency class, required test reports and the exact standards named in the purchase contract.
Also confirm insulation level, temperature-rise limits, cooling designation, oil specification and quantity, terminal arrangement, accessories, enclosure details, corrosion protection, installation altitude, ambient conditions, indoor or outdoor placement, seismic requirements, noise limits, IP rating where applicable, and short-circuit withstand requirements.
Obtain an approved outline drawing because the listed package measurements and the reference unit dimensions are not interchangeable. Warranty, spare parts, commissioning support, inspection scope, documentation package, production schedule and shipping terms should also be agreed in writing.
