When it comes to elevator installations, few components are as important as the traveling cable. This flexible, multi-conductor lifeline connects the elevator cab to fixed controls, powering lights, sensors, alarms, and more. Without it, the entire system cannot operate safely or reliably.
In this guide, you’ll learn how to select the right traveling cable for your elevator project. Additionally, we’ll highlight common mistakes, explain why code compliance matters, and recommend a trusted manufacturer. With the right cable, your elevator installation will perform efficiently and meet all safety expectations.
What Is Elevator Traveling Cable?
Elevator traveling cable is a flexible multi-conductor cable designed to move with the elevator car. It carries power, control signals, and communication data between the elevator controller and the moving cab. Unlike standard wiring, these cables are engineered to bend constantly without wearing out.
Typically, a traveling cable includes finely stranded copper conductors, shielded twisted pairs, coaxial lines, or fiber optics—depending on what the system requires. These elements are bundled together and wrapped in a flame-retardant outer jacket. As a result, the cable functions as the communication backbone of the elevator, allowing the cab to respond to every button press, sensor, and system call.
How to Choose the Right Cable
Choosing the correct traveling cable depends on your elevator’s design, features, and environment. The following sections explain the most important criteria to evaluate before you order cable.
1. Voltage and Power Needs
To begin, identify the voltage requirements for your elevator system. Most traveling cables are rated for 300V, which is suitable for lighting, control systems, and standard accessories. However, some elevators require cables or conductors rated for 600V to handle components like fans or high-output lighting.
Therefore, you should always check the voltage rating and conductor gauge against your system’s electrical load. Doing so ensures the cable won’t overheat or degrade from excess current. More importantly, it prevents long-term performance and safety issues.
2. Number of Conductors
Next, determine how many conductors your elevator requires. This includes wires for lighting, alarms, door sensors, intercoms, cameras, and access systems. For larger or more advanced elevators, the count may exceed 60 conductors.
Moreover, it’s smart to include several spare conductors in your design. These allow for future expansion and reduce the chance of needing to rewire later. Be sure to include a dedicated ground wire as well, since it’s required by code.
3. Signal Shielding
If your elevator includes data, video, or voice systems, shielding becomes essential. Shielded twisted pairs reduce electromagnetic interference (EMI), ensuring clean phone calls, stable video feeds, and noise-free intercom systems. Coaxial or CAT5/CAT6 lines are also common in elevators with CCTV or network-connected controls.
For that reason, always specify a cable that includes proper shielding for any sensitive components. Otherwise, performance issues may arise due to electrical noise from motors or nearby equipment.
4. Flexibility and Bending Life
Traveling cable flexes every time the elevator moves, which could be hundreds of times per day. Because of this, durability and flexibility are non-negotiable. Round traveling cables with finely stranded copper conductors perform well in these conditions.
Additionally, confirm that the cable’s minimum bend radius is compatible with the pulleys or loops in your hoistway. Cables that bend too tightly may wear out faster. By selecting cable designed for frequent bending, you’ll extend its life and reduce maintenance issues.
5. Elevator Travel Height
The total travel distance of your elevator directly affects your cable choice. For short and mid-rise elevators, jute-core cables usually provide enough support. However, high-rise elevators require steel-core traveling cables that support their own weight without stretching.
Furthermore, when installing cables in high-rise applications, you must use additional support methods such as saddles, clamps, or cable guides. These prevent excessive strain and ensure the cable stays in alignment over time.
6. Code Compliance
Beyond performance, safety and compliance are critical. In the United States, traveling cables must meet NFPA 70 (NEC) Article 620 and carry a UL listing as Type ETT. These certifications confirm the cable has passed flame tests and complies with durability standards.
Using a compliant cable not only ensures the job passes inspection—it also protects building occupants, your crew, and your reputation. As a result, choosing certified cable is one of the most important steps in the process.
Common Mistakes to Avoid
Even seasoned professionals sometimes make costly errors when selecting traveling cable. Below are common mistakes and how to avoid them:
Underestimating Conductor Count
One of the most frequent issues is underestimating how many conductors the system requires. For instance, failing to include a wire for a future card reader or camera could require installing an entirely new cable. To prevent this, always build in extra conductors for future needs.
Mismatching Voltage or Gauge
Choosing the wrong conductor size or voltage rating can lead to serious problems. For example, using an 18 AWG conductor for a fan motor might cause overheating or voltage drops. Always verify the electrical load and choose the right wire gauge accordingly.
Omitting Shielding
In elevators with communication lines, a lack of shielding leads to EMI-related issues. This might result in static on phone lines or distorted video feeds. Including shielded pairs or coax components helps maintain clean, uninterrupted signals.
Ignoring Travel Distance and Cable Weight
Some cables are only rated for short vertical runs. If you install a jute-core cable in a high-rise system, it might stretch or fail under its own weight. In contrast, steel-core cables are designed for longer runs and maintain performance without sagging or pulling.
Why Quality and Compliance Matter
Traveling cables are safety-critical components. Choosing a low-cost, non-compliant cable increases the risk of failure, safety violations, and costly rework. Conversely, selecting high-quality cable protects your crew, the elevator, and the building’s occupants.
Safety Standards
UL, CSA, and NEC-compliant cables meet strict fire, flexibility, and electrical performance standards. For example, cables rated UL VW-1 must pass vertical flame tests to ensure fire resistance. Compliance also protects you from legal or liability issues.
Long-Term Reliability
Premium cable manufacturers use better insulation, higher-quality copper, and more robust cable designs. As a result, these cables last longer, resist wear, and require fewer repairs. Over time, quality cables reduce service calls and lower total cost of ownership.
Inspection and Liability
Most elevator jobs must pass inspection. If the cable lacks UL certification or is visibly inappropriate for elevator use, inspectors will flag it. That can delay your project or force a costly redo. Therefore, always select certified cable with the required markings and documentation.
