What Are Elevator Traveling Cables?

Elevator traveling cables used to transmit signals and power between the elevator car and the control systems. This includes sending command for opening and closing of elevator doors and movement of the elevator car.
In addition, these cables transmits data from sensors to the control panel. The control system uses this information to manage and adjust the elevator’s operation, ensuring safe and efficient operation. These cables are generally made with copper conductors and PVC.

How Does Elevator Traveling Cable Work?

When a passenger press a button inside an elevator, the elevator traveling cable transmits the signal to the control system which then directs the elevator cabin to the desired floor.
Additionally, it transmits signals for door operations such as opening and closing of doors as well as safety features.
The traveling cable provides power to the elevator car for lights, ventilation, and any other electrical mechanisms inside.
The cables are designed to be flexible to bend as the elevator moves and up and down. The flexibility adds to its durability to endure constant motion without breaking.
To ensure uninterrupted communication and power flow, the cables maintain constant electrical connection as the elevator moves.

Types of Elevator Traveling Cable

An elevator traveling cable can either be flat or round regardless of the application. Choosing elevator traveling cable based on shape is a design-based choice, taking into consideration factors such as flexibility, space constraints, and installation requirements.

Flat Elevator Traveling Cable

This type of cables is designed by laying conductors in parallel, forming a flat configuration, and enclosing them in a protective sheath.
These cables are generally compact and can be more flexible, which makes them suitable for applications with limited space and where there is a need for tight bending.
Flat cables are typically used in standard applications and moderate travel distances because they are easier to handle, simpler to install, and can be neatly layered within the elevator shaft.

Round Elevator Traveling Cable

Round traveling cables are constructed by twisting conductors around a central core. This provides enhanced flexibility and allows for a larger number of conductors, often exceeding 120. These cables are designed to endure the mechanical stress of vertical movement.
Round cables are often selected for high-rise buildings or installations requiring complex routing due to their ability to bend in all directions. However, they can also be used in standard applications where those features are required.
