Recently, CEEG successfully developed its independently designed 8000 kVA epoxy cast resin dry-type 12-pulse rectifier transformer. This marks a milestone breakthrough for CEEG in the field of ultra-high-power rectifier transformers.
1. Six-Dimensional Performance for Exceptional Excellence
CEEG’s 12-Pulse Rectifier Transformer redefines industrial power equipment performance benchmarks through six core technological innovations. By deeply integrating breakthrough structural design with advanced material processes, it achieves comprehensive upgrades in electrical performance, safety protection, and energy efficiency.
① Large Capacity with Exquisite Structure
Single-unit capacity exceeds 8000 kVA, pushing manufacturing capabilities to new heights. The high-voltage multi-layer segmented structure enhances electrical performance, while vacuum epoxy resin casting with high-temperature curing ensures insulation reliability. Low-voltage copper foil winding technology significantly improves mechanical strength, achieving top-level deformation resistance.
② Electromagnetic Optimization with Safety Barrier
The high/low voltage axial split arrangement optimizes electromagnetic ampere-turn distribution, significantly improves short-circuit resistance, and increases fault protection response speed to milliseconds.
③ Exceptional Energy Efficiency – A Model of Energy Saving
Secondary winding output voltage difference <0.2%, reducing circulating currents between secondary windings and improving output power efficiency. No-load losses are low, achieving efficiency above 99.2%, in line with national energy-saving and emission-reduction policies, with excellent environmental performance.
④ Harmonic Purification – Guardian of the Grid
Effectively eliminates specific-order harmonics, providing excellent harmonic suppression and reducing power pollution to the grid.
⑤ Scene Adaptation – Cost Innovation
Suitable for high-power rectifier equipment, especially in scenarios requiring advanced harmonic control and power factor improvement, helping to reduce overall costs.
⑥ Safe Isolation – Dual Protection
Effectively provides electrical isolation between the rectifier and the grid, enhancing the safety of the rectifier system.
