Import 10kv-220kv Rectifier Transformer — Buy in Bulk from Supplier in China

This 10kV to 220kV rectifier transformer from Yugong Machinery is engineered as the AC power source for high-power rectifier equipment across industrial sectors. Its primary (line) side connects to the AC grid, while the secondary (valve) side connects directly to the rectifier. The design accommodates the non-linear, harmonic-rich load currents inherent to rectifier applications, requiring specialized winding configurations and robust construction to handle the electrical stresses.

The transformer features a variety of special coupling methods on the valve side, such as dual-back-star with inter-phase reactor or six-phase bridge, to meet different process requirements. Advanced techniques like star-delta winding phase displacement and phase-shift windings are employed to improve the system's power factor and reduce harmonic currents on the line side. Yugong's manufacturing process incorporates procedural design, numerical electric field analysis, and insulation breakdown studies to enhance product reliability.

Buyers for this equipment include operators in general industrial, electrochemical electrolysis, DC power transmission, traction frequency, and variable frequency power supply sectors. The supplier references a recent project supplying 220kV on-load-tap rectifier transformers for a major 600,000-tonne caustic soda plant. Specific commercial terms such as pricing, MOQ, and lead times are not listed and must be negotiated directly with the supplier.

Yugong Machinery Co., Ltd. operates from No.1288 Luban South Road, Yugong Industries, Tengzhou 277500, Shandong, China. The supplier profile is categorized with an 'imported' tier and a 'harbor' trust tier. The company states it collaborates with domestic colleges and universities on research projects related to transformer design, including insulation technology and loss calculation.

The listing highlights the company's manufacturing experience in rectifier transformers over 'many years,' claiming major breakthroughs beyond traditional calculation methods. However, the profile does not provide specific founding dates, employee counts, annual production capacity, or a list of certified clients. The response rate is currently listed as 0.00%, which buyers should consider when evaluating communication reliability for project coordination.
