3: Vehicle vibration.
3: Vehicle vibration W+G
W – Self weight G – Gravity generated by vertical vibration
Schematic diagram of gravity changes caused by vehicle vibration
4: Others
① Effects of various chemicals (oils, detergents, etc.) on accelerated aging of cable sheaths.
② Outdoor sunlight (UV), temperature differences during long-distance operation, and weathering can all affect cable aging.
③ The impact of high-speed airflow on cable impact and oscillation when passing through vehicles.
④ Fire safety meets the requirements of EN45545-2.
⑤ The cable material meets the requirements for prohibited substances for railways.
