Elevator systems are the lifelines of modern infrastructure, but they are only as reliable as the connections that run them. For engineers and building managers, the traveling cable is often the single most critical point of failure. It undergoes constant motion, immense mechanical tension, and environmental stress.
At Shanghai Rousheng, we understand that a standard cable often isn’t enough. Our Cold-Resistant Elevator Composite Cable is engineered to solve three specific problems: cable brittleness in low temperatures, signal interference in video feeds, and the messy inefficiency of running multiple cables for power and data.
Engineered for Extreme Flexing and Cold Environments
The biggest enemy of a traveling cable is the combination of cold weather and constant bending. Standard PVC jackets stiffen when the temperature drops, leading to micro-cracks in the sheath. Over time, these cracks expose conductors, leading to short circuits or complete system failure.
Our flat lift monitoring cable utilizes a proprietary, high-flexibility PVC compound. This material remains pliable even in temperatures as low as -30°C to -40°C. Whether installed in an unheated panoramic elevator in Northern Europe or a high-rise logistics center, the sheath maintains its integrity, ensuring a lifespan that significantly exceeds standard traveling cables.
The “All-in-One” Composite Solution
Space inside the elevator shaft is premium real estate. Running separate lines for CCTV, power, and network data is inefficient and increases the risk of tangling or “corkscrewing.”
This composite cable integrates three vital functions into a single, flat profile:
- Video Transmission: Coaxial cores for crystal clear analog video.
- Network/Data: Integrated twisted pairs (Cat5e/Cat6 equivalent) for IP cameras and digital signage.
- Power: Dedicated power cores to run cameras, sensors, and lighting.
By combining these into a flat structure, we achieve a smaller bending radius and tighter stacking capabilities compared to round cables.
Tensile Strength and Signal Integrity
A cable hanging from a 30-story height bears its own weight, which can stretch copper conductors to the breaking point. To counteract this, our design incorporates dual high-tensile steel wire ropes embedded parallel to the core. These steel members absorb the tensile load, ensuring the copper conductors carry only the signal, not the weight.
Furthermore, elevator shafts are electrically noisy environments. Motors and variable frequency drives (VFDs) generate significant electromagnetic interference (EMI). Our cable features high-density shielding (braided copper and aluminum foil options) to reject this noise, preventing the “ghosting” or signal loss often seen on elevator security feeds.

Frequently Asked Questions (FAQ)
Q: Can this cable support IP Cameras for digital monitoring?
A: Yes. The composite design includes network data pairs specifically designed for IP camera transmission, ensuring stable high-bandwidth connectivity alongside power delivery.
Q: What is the maximum suspension length for this cable?
A: Thanks to the dual steel wire reinforcement, this cable is suitable for suspension lengths up to 150m (standard) and can be customized for higher-rise applications up to 300m upon request.
Q: How does the flat design compare to round cables?
A: Flat cables dissipate heat better and flex more uniformly in one plane. This eliminates the internal twisting (corkscrewing) common in round cables, significantly extending the mechanical life of the system.
Q: Is this cable suitable for outdoor panoramic elevators?
A: Absolutely. The UV-resistant and cold-resistant PVC sheath makes it ideal for outdoor or exposed elevator shafts where environmental protection is required.
