Application of high-speed rail transit switch High-speed railway and rail transport industry
1. The switches shall pass functional tests with stable performance. Their mechanical service life can support more than 10 years of operation without functional failures during service.
2. The switches feature excellent temperature resistance, with an operating ambient temperature range from -40℃ to 95℃. They also offer good resistance to humidity and salt spray, ensuring stable on-off performance under various extreme and complex climatic conditions.
3. High resistance to vibration is required. Tests are carried out in accordance with Chinese standard GB/T21563-2008 and international standard IEC61373:1999, to ensure all components of the switch stay securely assembled under high-vibration conditions with no functional failure.
