[0002] Elevator traveling cables are professional cables used in elevator operation. There are elevator traveling cables for video surveillance and elevator traveling cables for digital networks. Elevators are indispensable transportation equipment in high-rise buildings and they need to move up and down frequently.

However, existing elevator traveling cables often become brittle and break due to low temperatures in cold places, causing the cables to be damaged and unable to work normally. In addition, during the use of the cables, they are prone to friction with the surrounding environment, causing damage to the outside of the cable body and shortening the cable's service life. For this reason, we have proposed a cold-resistant elevator traveling cable. Utility Model Content
