High-Flex TPU Pipeline Robot Cable / CCTV Coaxial Cable

High-Flex TPU Pipeline Robot Cable / CCTV Coaxial Cable

Reliable Power and Signal Transmission for Demanding Pipeline Inspections

Pipeline inspection robots and CCTV crawler systems operate in some of the harshest conditions found in industrial and municipal infrastructure. Tight bends, continuous pulling, abrasion against pipe walls, moisture, oil, and signal interference all place extreme demands on the cable connecting the system.

High-Flex TPU Pipeline Robot Cable / CCTV Coaxial Cable is purpose-built to meet these challenges. Rather than adapting a standard industrial cable, this solution is engineered specifically for robotic inspection environments where flexibility, durability, and signal integrity are equally critical.

Manufactured by Shanghai Rousheng Wire & Cable Co., Ltd., a specialist in high-flex drag chain and special-purpose cables, this product is designed to perform reliably over long service cycles in real-world inspection work.

Why the Cable Is a Critical Component in Pipeline Robotics

In pipeline inspection systems, the cable is more than a power line—it is the lifeline of the robot. Common failure points in conventional cables include conductor fatigue, jacket wear, water ingress, and unstable video signals.

A well-designed cable must:

• Maintain flexibility under repeated bending and torsion

• Withstand abrasion and pulling forces inside confined pipes

• Deliver stable power and clear video signals over long distances

• Resist water, oil, sewage, and chemical exposure

The High-Flex TPU Pipeline Robot Cable / CCTV Coaxial Cable addresses these requirements at both structural and material levels, ensuring consistent performance throughout the inspection process.

Composite Cable Structure Designed for Integration

Integrated Power, Signal, and Coaxial Transmission

This cable combines power conductors, control or signal cores, and dedicated coaxial elements into a single compact structure. The integrated design simplifies system layout, reduces overall diameter, and improves handling during deployment and retrieval.

High-Purity Copper Conductors

Fine-stranded oxygen-free copper conductors are used to ensure:

• Low electrical resistance over extended cable lengths

• Stable voltage supply to robotic drive and lighting systems

• Reliable data and control signal transmission

Dedicated Coaxial Core for CCTV Video

The coaxial unit features optimized impedance and multi-layer shielding to minimize attenuation and electromagnetic interference, supporting clear and stable video transmission even in electrically complex environments.

TPU Outer Jacket: Built for Harsh Pipeline Conditions

Advantages of TPU in Inspection Applications

The outer jacket is made from high-performance thermoplastic polyurethane (TPU), selected for its superior mechanical and environmental properties:

• Excellent abrasion resistance against pipe walls and debris

• High tear strength under dynamic load

• Outstanding flexibility at low temperatures

• Resistance to oil, sewage, grease, and mild chemicals

Compared with PVC or conventional rubber jackets, TPU significantly extends service life in confined and abrasive environments.

Reduced Drag Inside Pipelines

The smooth jacket surface lowers friction during operation, reducing mechanical stress on the robot and cable reel system while improving overall efficiency.

High-Flex Performance for Continuous Movement

Optimized for Repeated Bending

Internal stranding geometry and lay length are designed for continuous dynamic motion, allowing the cable to withstand frequent bending during deployment, navigation, and retrieval.

Torsion Resistance

The internal structure maintains stability during rotational movement, helping prevent conductor displacement and extending operational lifespan in crawler systems that twist or turn inside pipelines.
