This pure power watertight cable is specifically designed for underwater and harsh-environment applications requiring reliable AC or DC power delivery. It integrates three 2.5 mm² stranded tinned copper conductors into a multi-layer water-sealed structure. Utilizing PE (Polyethylene) as the core insulation material, the cable provides excellent dielectric properties, very low moisture absorption, and radial watertight performance. It is ideal for applications such as ROV power feeders, subsea junction boxes, shipboard bulkhead power distribution, offshore platforms, underwater lighting, and pumping systems - where continuous power transmission and absolute water sealing are critical. By combining good electrical conductivity with extreme environmental resistance, this cable ensures stable operation even under deep-sea pressure and long-term seawater immersion.

Key Features – PE Insulated Power Cores
PE-insulated 2.5 mm² conductors offer low DC resistance for efficient power delivery, a wide -40°C to +105°C operating range, negligible moisture absorption, excellent chemical 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) requiring dedicated power tether without integrated signal lines
Submarine and shipboard bulkhead power cables with watertight penetrations
Subsea observatories and ocean monitoring networks (cabled power nodes for instruments)
Offshore drilling platforms and marine renewable energy systems
Underwater pumps, thrusters, cameras (power-only feeds), and environmental sensor arrays
Military and defense underwater power distribution systems
Any underwater application demanding reliable power transmission + watertight integrity without mechanical tension requirements
This cable simultaneously satisfies underwater equipment needs for efficient power delivery and robust water sealing under high hydrostatic pressure.
It is an ideal solution for fields such as marine engineering, subsea infrastructure, oceanographic research, and underwater defense power systems.
