The RONA RECH 16×0.3mm² transverse watertight underwater cable is a specialized transmission solution engineered to solve the most challenging problems in water-exposed and subsea industrial applications. Built on the innovative "radial all-sealed protection + multi-environment adaptability" principle, this 300/1000V underwater cable integrates finely stranded tinned copper conductors with a composite insulation and sheath structure to deliver reliable power and signal transmission in harsh aquatic environments. Unlike traditional underwater cables that suffer from radial moisture penetration, corrosion, and insulation degradation, our transverse watertight cable provides complete protection against water ingress, ensuring uninterrupted operation from shallow coastal waters to mid-depth subsea installations. It serves as a critical lifeline for subsea automated systems, marine infrastructure, and high-humidity industrial facilities.
The defining feature of this submarine cable is its advanced transverse watertight design, which creates a continuous radial seal along the entire length of the cable. This effectively blocks moisture penetration even if the outer jacket is damaged, preventing water from traveling along the conductor and causing catastrophic system failure. This technology addresses the single most common cause of underwater cable failure, significantly improving system reliability and reducing maintenance costs in remote or hard-to-access locations.
Constructed with finely stranded tinned copper conductors compliant with VDE 0295 Class 5, this saltwater resistant cable offers exceptional corrosion resistance in saltwater and brackish environments. The chloroprene rubber outer sheath provides high tensile strength, tear resistance, and UV aging protection, ensuring long-term performance even when exposed to harsh marine weather conditions, salt spray, and tidal immersion.
Engineered to operate in the most demanding temperature conditions, this waterproof signal cable supports fixed installation temperatures from -40℃ to 90℃ and moving installation temperatures from -35℃ to 90℃. Its ethylene propylene rubber (EPR) or fluorinated ethylene propylene (FEP) insulation delivers high dielectric strength and stable corona resistance, maintaining electrical performance across extreme temperature fluctuations without degradation.
Designed to withstand the mechanical stresses of subsea operations, this ROV underwater cable resists torsion from robotic arms and drag from ocean currents. Its flexible construction allows for smooth movement in dynamic applications, while its compliance with IEC 60332-1 flame-retardant standards ensures safety in both underwater and above-water installations. With an insulation resistance of ≥500 MΩ·km, it provides enhanced electrical safety for critical systems.

This offshore platform cable is indispensable for a wide range of water-exposed industrial applications. In underwater industrial automation, it powers and controls remotely operated vehicles (ROVs), submersible motors, and underwater welding systems, withstanding the mechanical stresses of robotic manipulation and ocean currents. It is widely used in marine and water engineering projects, including offshore platform power supply, bridge structural monitoring systems, and aquaculture aeration setups, where resistance to saltwater and tidal immersion is critical. Additionally, it serves as a reliable connection for subsea sensor cables in offshore surveying operations, enabling stable data transmission from water quality monitors and environmental sensors. It is also ideal for high-humidity industrial settings such as printing and dyeing workshops, wastewater treatment plants, and port cranes.
Standard waterproof cables only protect against surface water penetration, while transverse watertight cables feature a radial seal that prevents water from traveling along the length of the cable even if the outer jacket is damaged. This makes them far more reliable for long-term subsea and underwater applications.
This cable is designed for shallow to mid-depth underwater applications up to 100 meters. For deeper subsea installations, we offer specialized high-pressure rated cables tailored to your specific depth requirements.
Yes, we offer both EPR and FEP insulation options. EPR provides excellent flexibility and cost-effectiveness for most applications, while FEP offers superior chemical resistance and higher temperature performance for more demanding environments.
