Vehicle jumper cable

Vehicle jumper cable

The jumper is an off-board cable used for electrical connections between railway vehicles. This is a special type of cable that must withstand various mechanical changes, climate changes, and various chemical attacks. This type of cable has high reliability and safety. The following factors should be considered:
Product Details
1: Mechanical impact of train operation status on cables.

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.
