Qingdao Hengfengyou Electric Engineering Co., Ltd. supplies three phase transformers rated from 10kVA to 2500kVA, designed for step-up and step-down voltage conversion in industrial, commercial, and utility applications. The transformer cores use imported cold-rolled silicon steel sheet, a material choice that reduces no-load losses and no-load current. Windings are wound from oxygen-free copper: low-voltage units up to 500kVA employ a double-layer cylinder structure, while 630kVA and above use double or four-helix configurations. The high-voltage side uses a multi-layer cylinder arrangement throughout the range.
These transformers use a Dyn11 connection group, which suppresses third-harmonic currents and helps maintain grid power quality. The fully sealed tank receives three coats of primer and one finish coat on all internal and external surfaces, providing resistance to salt fog, moisture, and fungal growth. Measured noise levels fall below the relevant national standard, and under normal operating conditions the units are maintenance-free. Buyers should confirm exact voltage ratios, cooling method (ONAN/ONAF), and insulation class with the supplier before ordering, as these details are not listed in the current specification sheet.

Importing 10-2500kVA Three Phase Transformers from Qingdao Hengfengyou Electric Engineering Co., Ltd. in China
When sourcing 10-2500kVA three phase transformers from China, buyers should verify that the supplier can provide test reports, type-test certificates, and compliance documentation relevant to their destination market. Qingdao Hengfengyou Electric Engineering Co., Ltd. is based in Qingdao, Shandong Province, a region with established electrical manufacturing infrastructure. Requesting factory audit reports or third-party inspection before shipment is a standard practice for power equipment procurement.
Transformer procurement often involves customisation of voltage ratios, tap changers, cooling arrangements, and enclosure ratings. Before finalising a purchase order with Qingdao Hengfengyou, confirm all technical specifications in writing, including insulation class, impedance voltage, and noise level guarantees. Ask the supplier about warranty terms and after-sales support, particularly for units above 630kVA where installation and commissioning complexity increases.
Import duties, local grid compliance requirements, and transport logistics vary by destination country. Buyers in Southeast Asia, Africa, and the Middle East frequently source transformers from Shandong Province manufacturers. Work with a freight forwarder experienced in heavy electrical equipment to arrange appropriate container or breakbulk shipping from Qingdao port.
