The operating environment of rail transit and high-speed train equipment is complex, and there are strict standards for the safety, stability, anti-interference, and vibration resistance of magnetic core products. Shenye lattice magnetic cores are widely used in key parts such as high-speed train traction converters, auxiliary power supplies, current/voltage transformers, signal detection, filtering systems, and control systems to ensure stable train operation and safe driving. The product is made of amorphous, nanocrystalline, and high-grade silicon steel materials, which have the advantages of wide temperature range stability, low loss, high precision, strong anti-interference, and long service life. It can adapt to high-speed operation, strong vibration, high current, and complex electromagnetic environments. We strictly follow the quality system requirements of the rail transit industry, ensuring high consistency and reliability of our products from raw materials, production to testing. We provide safe, efficient, and stable magnetic core matching for rail transit equipment such as high-speed trains, subways, and intercity trains, and help promote the intelligent and efficient development of rail transit.
