This hybrid watertight cable is specifically designed for underwater and harsh-environment applications requiring simultaneous medium‑power delivery and multiple independent signal channels. It integrates two 17 AWG power conductors and four individually twisted pairs (4×2×24 AWG) for low‑voltage signal transmission into a multi‑layer water‑sealed structure. Utilizing PE (Polyethylene) as the core insulation material for all electrical elements, the cable provides excellent dielectric properties, very low moisture absorption, and radial watertight performance. It is ideal for applications such as ROVs, subsea sensor arrays, shipboard instrumentation, offshore platforms, and underwater control systems - where reliable power distribution and multiple noise‑immune signal paths are critical, all within a watertight envelope. By combining good electrical characteristics with robust environmental resistance, this cable ensures stable operation even under deep‑sea pressure and long‑term seawater immersion.

Key Features – PE Insulated Power & Signal Cores
PE‑insulated 17 AWG power conductors offer low DC resistance for efficient power delivery. The four 24 AWG twisted pairs provide independent signal paths suitable for RS‑422, RS‑485, 4‑20 mA loops, or low‑speed digital control. PE insulation ensures a wide -40°C to +105°C operating range, very low moisture absorption (ideal for underwater use), excellent resistance to seawater and many hydrocarbons, and good flexibility. 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 separate power and multiple sensor/control signal lines
Shipboard and submarine bulkhead cables with watertight penetrations for distributed sensor networks
Subsea observatories and ocean monitoring nodes (cabled multi‑sensor arrays with individual RS‑485 channels)
Offshore drilling platforms and marine renewable energy systems
Underwater cameras, lights, and actuator assemblies needing both power and dedicated control pairs
Military and defense underwater communication and control systems
Any underwater application demanding reliable multi‑channel signal transmission + DC power + watertight integrity without mechanical tension requirements
This cable simultaneously satisfies underwater equipment needs for stable power delivery and multiple independent signal lines under high hydrostatic pressure.
It is an ideal solution for fields such as marine engineering, subsea instrumentation, oceanographic research, and underwater defense control systems.
