Rona specialized watertight cables and connectors are designed for a wide range of subsea and marine applications, including ocean engineering, underwater exploration and monitoring, aquaculture, hydraulic engineering, offshore wind power, oil platforms, and submarine optical cables. They provide safe, stable, and efficient power transmission and signal control for equipment operating anywhere from shallow waters to deep-sea environments up to 11,000 meters.
Featuring multi-layer sealing structures (e.g., dual O-rings and pressure-adaptive sealing) and corrosion-resistant materials such as titanium alloy and nickel-aluminum bronze, our products offer high waterproof performance and can withstand hydrostatic pressures up to 140 MPa. They are operational in extreme temperatures ranging from -40°C to 80°C.
Key performance metrics are on par with leading international brands, including:
Contact resistance: ≤10 mΩ
Insulation resistance: ≥500 MΩ
Mechanical durability: over 300 mating cycles
