What is an elevator traveling cable?

Elevator traveling cables are specialized cables used in elevator operation. There are elevator traveling cables for video surveillance and those for digital networks. This article mainly introduces elevator traveling cables for digital networks. Elevators are indispensable transportation facilities in high-rise buildings. They frequently move up and down, and the cables that provide power for the elevators also inevitably move up and down along with them. Moreover, with the development of technology and the needs of people's work and life, there also need to be some activities such as communication and monitoring within the elevators.

For this reason, during the high-speed movement of the elevator, the wind resistance of the cables is large, causing the cables to be frequently pulled, which affects their service life. Due to the excessive complexity of various circuits, these circuits have relatively poor tensile performance. After long-term and frequent lifting and lowering movements, they may break or be damaged, resulting in power failure, stoppage or interruption of other related functions. As the elevator speed increases, The greater the wind resistance of the cable, the lower the speed range the elevator can operate at to ensure the safe operation of the cable, which affects the work efficiency.

The elevator traveling cable is a type of traveling cable with data signal transmission or power lines. It contains steel wire support components, which effectively solve the problems existing in the operation of elevators due to wires and cables.

The performance characteristics of elevator traveling cables

The elevator traveling cable is composed of a communication cable and a power cord. The communication cable is usually a network data cable. The internal conductor can be a single or twisted soft copper wire. The outside of the conductor has an insulating layer and a sheath layer. The power cord can be selected in different specifications and models according to the purpose of the power supply. The power cord conductor adopts a multi-strand twisted structure, which is flexible. The communication cables are isolated from each other by filled insulating materials. In the elevator traveling cable, there are two steel wires, which serve as load-bearing and tensile components.

The network data cable, power cord and load-bearing tensile components are all included in a flat elevator traveling cable, which greatly reduces the number of cables in the elevator shaft, facilitates elevator maintenance and saves installation space. During the operation of the cable along with the elevator, due to the presence of steel wires, the self-weight of the cable and the external force of pulling are all borne by the reinforcing steel wires Protecting cables from damage, effectively reducing the number of elevator cables, greatly facilitating the operation of elevators, and also ensuring the safe operation of elevator cables.
