Henan Tinde Power Co., Ltd. manufactures large power transformers rated above 250 MVA for utility‑scale applications. The units use a cold‑rolled grain‑oriented (CRGO) electrical steel core and electrolytic copper windings of Cu‑ETP 99.9 % purity. Cooling is provided by mineral oil or ester oil, while the insulation system consists of Nomex/Kraft paper. Transformers are available with off‑load or on‑load tap changers and operate at system voltages from 110 kV up to 765 kV.
In the industry, typical efficiency for transformers of this size exceeds 98 % and the standard insulation class is B, complying with IEC 60076 and ANSI/IEEE standards. A common cooling classification is ONAN/ONAF, which matches the heat‑dissipation requirements of high‑power installations. Standard core thickness for CRGO steel in this rating range is 0.35 mm, and winding loss is usually limited to 0.5 % of rated power. These technical baselines ensure that the equipment can be integrated into generation, step‑up, step‑down or inter‑tie configurations without bespoke redesign.
Utility companies, independent power producers and grid operators are the primary buyers of such transformers. Units are shipped internationally in flat‑rack containers or as break‑bulk cargo, and buyers should confirm container dimensions and handling requirements. Because the listing does not state minimum order quantity, lead time or Incoterms, importers must verify those details directly with the supplier before placing an order. Payment terms and warranty conditions are also subject to negotiation and should be clarified in the contract.

Henan Tinde Power Co., Ltd. is registered at 15th Floor, Block D, Building 18, No.283 Xisanhuan Road, High‑Tech District, Zhengzhou, Henan 450000, China. The company is listed as a harbour‑tier supplier, indicating it meets the platform’s verification criteria, although its response rate is currently recorded as 0 %.
The supplier states that its large power transformers are manufactured in accordance with IEC 60076 and relevant ANSI/IEEE standards, and that they can be customised with off‑load or on‑load tap changers, multi‑winding or auto‑transformer designs. No specific information about minimum order quantities, lead times or pricing is provided in the listing, so buyers should request those details directly.
Large power transformers rated above 250 MVA are critical components in power generation and grid infrastructure. These generator step-up (GSU) and network intertie transformers typically operate at voltages ranging from 110kV to 765kV, featuring either off-load or on-load tap changers for voltage regulation. As heavy industrial capital equipment, they are shipped internationally via flat-rack containers or breakbulk vessels, making them a significant category in global electrical equipment trade.

Before placing an order, importers should request the IEC 60076 test report, any ANSI/IEEE compliance certificates, and a material test certificate for the CRGO steel core and copper windings. Verifying the exact voltage class, tap‑changer configuration and insulation class will ensure the transformer matches the target grid specifications and climate conditions.
Logistics for large power transformers typically involve flat‑rack containers or break‑bulk vessels; buyers must confirm container dimensions, weight limits and handling equipment at the destination port. Lead‑time, Incoterms such as CIF or FOB, and payment terms are not disclosed, so they should be negotiated and documented in the purchase agreement to avoid unexpected delays or costs.
Quality assurance commonly includes factory acceptance testing, partial discharge measurement and oil dielectric testing. Importers are advised to arrange a third‑party inspection before loading and to obtain the full test report, warranty certificate and as‑built drawings to support commissioning and future maintenance.
