ROV Tethers for underwater robot

In underwater cable manufacturing, if you don’t solve the problems of tangling and signal loss, everything else is pointless.

Anyone involved in ROVs knows that cables are the lifeblood of the robot. However, in actual operation, the most troublesome issue is often not equipment failure, but cable malfunction:

• It’s advertised as zero buoyancy, but it starts sinking shortly after being submerged, or drifts erratically, getting caught in the thrusters.
• Insufficient tensile strength means it breaks easily when snagged on bottom obstacles, causing equipment costing hundreds of thousands or even millions to lose connection.
• Poor shielding results in static underwater transmissions and severe data packet loss.

As a domestic manufacturer specializing in ROV tethers, we don’t mince words; we solve these key performance indicators:

• Buoyancy precision down to the gram: Through physical foaming and density closed-loop control technology, we ensure that every cable achieves true neutral buoyancy in both seawater and freshwater. No drifting, no sinking—that’s what makes your ROV smooth to control.
• High-Tensile Strength: The entire cable core is reinforced with Kevlar braids, allowing even small-diameter cables to withstand instantaneous tensile forces of several hundred kilograms. It can withstand not only normal operation but also emergency equipment removal.
• Truly Watertight: Many cables will rot if the outer sheath is damaged, as water will seep into the gaps. Our product achieves longitudinal watertightness; even if the outer sheath is partially damaged, water will not seep in, protecting your expensive components and equipment.
• Interference Resistance and Stability: Signal and power lines are laid out separately with double-layer shielding. No matter how high the power output, 4K video signal transmission will be flicker-free.

Why choose us instead of those imported brands or ordinary cable manufacturers?

• Faster and Cheaper than Brands: Foreign brands are several times more expensive, with lead times often exceeding three months. We are located in China, with ample stock and extremely fast delivery for customized specifications, saving you a significant amount of project budget.
• We Understand Operating Conditions: We don’t just manufacture cables; we have studied countless cases of failed underwater operations. Our cable sheaths are abrasion-resistant, UV-resistant, and corrosion-resistant, specifically designed for the harsh environment of seawater, not modified from ordinary industrial cables.
• Flexible minimum order quantity: While other companies may require a minimum order of 500 meters, we support research institutions and startups. Even if you only need a few dozen meters for testing, we’ll accept it.

The underwater environment is complex; don’t let your cables become a weakness.
