Reliability where it matters most: deep underwater and in constant motion.
In the demanding world of subsea exploration and industrial automation, cable failure isn’t just an inconvenience—it’s a mission stopper. The Shanghai Rousheng High-Flex ROV Cable is engineered to withstand the brutal realities of dynamic stress. Whether you are powering a Remotely Operated Vehicle (ROV) 200 meters below the surface or equipping a multi-axis industrial robot, this cable delivers continuous power and precise signal transmission without compromising flexibility.
Unlike standard cabling that stiffens or snaps under constant torsion, our cable utilizes fine-stranded twisted copper conductors and a specially modified PVC compound. This combination ensures high tensile strength and superior resistance to seawater, oil, and abrasion, extending the operational lifespan of your equipment and reducing costly downtime.
Key Performance Features
- Engineered for Torsion & Flex: Designed to handle repetitive bending and torsional stress (up to ±180°), making it ideal for drag chains and robotic arms that never stop moving.
- Superior Signal Integrity: High-purity, oxygen-free twisted copper conductors ensure stable data transmission, critical for real-time video feeds and control signals in underwater environments.
- Rugged Modified PVC Jacket: Our specialized outer sheath offers the durability of industrial-grade protection—resisting hydrolysis, oil, and microbial attack—while maintaining the flexibility required for tight bending radii.
- High Tensile Strength: Integrated reinforcement allows the cable to bear significant mechanical loads, a necessity for tethering applications and deep-water retrieval.
- Neutral Buoyancy Options: Available designs can approach neutral buoyancy, minimizing drag and allowing for smoother vehicle maneuverability in water.

Frequently Asked Questions (FAQ)
Q: Can this cable withstand continuous saltwater exposure?
A: Yes, the modified PVC jacket is specifically formulated to resist hydrolysis and microbial degradation common in seawater environments, ensuring long-term performance for subsea applications.
Q: Is this cable suitable for drag chains with tight bends?
A: Absolutely. The cable is constructed with a fine-stranded copper conductor and a pressure-extruded sheath that prevents “corkscrewing.” It supports a bending radius as small as 7.5x the cable diameter in motion.
Q: Do you offer custom core counts or hybrid cables?
A: Yes, Shanghai Rousheng specializes in customization. We can integrate power, signal, and data cores (including twisted pairs for communication) into a single high-flex sheath to meet your specific equipment needs.
Q: How does this cable handle electromagnetic interference (EMI)?
A: For signal-sensitive applications, we offer versions with high-density tinned copper braiding (over 85% coverage), effectively shielding your data from external electrical noise.
