Rail Transit｜High speed EMU Case
As core passenger transport equipment in rail transit, high speed electric multiple units (EMUs) run under rigorous conditions of high speed vibration, frequent start stop cycles and dynamically fluctuating voltages. Dense on board electrical equipment creates complex electromagnetic environments that readily produce power quality issues including harmonic interference, inrush currents and voltage surges, triggering hidden troubles such as on board electric control faults, equipment abnormal noise and component aging. Special purpose transformers and reactors for high speed EMUs act as key supporting components of on board power systems, performing core functions such as voltage conversion, galvanic isolation, harmonic suppression, current stabilization and electromagnetic compatibility protection. Custom developed against strict industry standards for high reliability, high safety, vibration resistance, low loss and strong electromagnetic compatibility for high speed EMUs, our products deliver superior stability, ultra low noise, wide range temperature tolerance and strong anti interference performance compared with general purpose industrial products. They eliminate operational hidden dangers of on board electrical equipment and guarantee safe, smooth and efficient full journey operation of high speed EMUs.
