Rail Transit Cable & Wire Harness Solutions
Railway sensor and control cables for high-speed rail and subway — IP67, anti-vibration, high-temperature and UV resistant.

Ride reliability, not just speed — by SAOJIE
Trains run on signals and sensors that can't afford to drop out. Our railway line covers sensor, detector and control cables for high-speed rail and subway projects, with IP67 sealing and anti-vibration construction.
High-temperature and UV-resistant jackets handle the exposure between cars and along the track. We build to project drawings and deliver in cut-to-length and harnessed form.
- Railway sensor & detector cables
- Control & signal harness (IP67)
- High-temperature, anti-vibration wiring
