This pure power watertight cable is specifically designed for underwater and harsh-environment applications requiring reliable multi-conductor power or control signal delivery. It integrates eight 1.5 mm² stranded bare copper conductors into a multi-layer water-sealed structure. Utilizing PP (Polypropylene) as the core insulation material and TPU (Thermoplastic Polyurethane) as the outer sheath, the cable provides excellent dielectric properties, low moisture absorption, outstanding abrasion resistance, and radial watertight performance. It is ideal for applications such as ROV power distribution, subsea junction boxes, shipboard bulkhead wiring, offshore platforms, underwater lighting, sensors, and valve actuators - where multiple independent power or control circuits and absolute water sealing are critical. By combining good electrical conductivity with robust environmental and mechanical resistance, this cable ensures stable operation even under deep-sea pressure and long-term seawater immersion.

Key Features – Bare Copper Conductors, PP Insulation & TPU Sheath
Bare copper conductors (8×1.5 mm²) – excellent electrical conductivity for efficient power or low-voltage control signal transmission; corrosion-resistant in dry or sealed environments.
PP insulation – offers a wide -40°C to +105°C operating range, very low moisture absorption (ideal for underwater use), good dielectric strength, and resistance to seawater, oils, and many chemicals.
TPU outer sheath – provides exceptional abrasion resistance, high tensile strength, UV stability, flexibility even at low temperatures, and resistance to marine biofouling, oils, and hydrolysis.
Multi-layer watertight construction – radial water sealing under high hydrostatic pressure, preventing longitudinal water ingress even if the jacket is nicked.
Ideal For
Subsea robots (ROVs/AUVs) requiring multi-conductor power tether without integrated signal lines
Submarine and shipboard bulkhead power cables with watertight penetrations for multiple circuits
Subsea observatories and ocean monitoring networks (cabled power nodes for instruments)
Offshore drilling platforms and marine renewable energy systems
Underwater pumps, thrusters, valves, and lighting fixtures needing separate power feeds
Military and defense underwater power distribution systems
Any underwater application demanding reliable multi-conductor power transmission + watertight integrity without mechanical tension requirements
This cable simultaneously satisfies underwater equipment needs for efficient multi-circuit 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.
