Hybrid Watertight PE Insulated PUR Jacketed Industrial Marine Cable For ROV & Subsea Systems

This hybrid watertight cable is specifically designed for underwater and harsh-environment applications requiring simultaneous DC power delivery and reliable RS485 serial communication. It integrates two 1.5 mm² power conductors and one shielded RS485 twisted pair (2×0.5 mm²) into a multi-layer water-sealed structure. Utilizing PE as the core insulation material for all electrical elements, the cable provides radial watertight performance, making it ideal for applications such as ROVs, subsea sensors, shipboard instrumentation, offshore platforms, and marine control systems - where stable power supply and noise-immune RS485 data transmission are critical, all within a watertight envelope. By combining excellent dielectric properties with extreme environmental resistance, this cable ensures reliable operation even under deep-sea pressure and long-term seawater immersion.

Key Features – PE Insulated Cores & Shielded RS485 Pair

PE-insulated power and RS485 signal cores offer superior electrical integrity, a wide -40°C to +105°C operating range, negligible moisture absorption, excellent chemical resistance, and inherent flame retardancy. The RS485 twisted pair is individually shielded (overall foil/braid) to ensure outstanding EMI rejection and long-distance differential signaling. Multi-layer water-blocking and pressure-resistant construction guarantees absolute watertight integrity without requiring mechanical tension strength.

Ideal For

Subsea robots (ROVs/AUVs) and underwater instruments requiring sensor data acquisition and DC power distribution

Shipboard and submarine control systems with watertight bulkhead penetration for RS485 networks

Subsea observatories and ocean monitoring nodes (cabled sensor arrays using Modbus/RS485)

Offshore drilling platforms and marine renewable energy equipment

Military and defense underwater communication and control systems

Any underwater application demanding reliable low-voltage power + RS485 communication + watertight integrity without mechanical tension requirements

This cable simultaneously satisfies underwater equipment needs for stable power delivery and noise-immune RS485 serial data transmission under high hydrostatic pressure.

It is an ideal solution for fields such as marine engineering, subsea instrumentation, oceanographic research, and underwater defense control networks.
