PDK81301-5*0.75 Underwater Power Cable

This product is a 5-conductor pure power watertight (submersible) cable, purpose-built for high-power underwater equipment operating at significant depths (such as deep-sea ROV thrusters, subsea hydraulic power units, high-capacity pumps, and offshore drilling auxiliary systems). It delivers high current capacity with low voltage drop, while maintaining robust watertight integrity and excellent resistance to dynamic bending in rough subsea conditions. This cable carries no signal or fiber cores, making it the optimal choice for applications that demand clean, high-amperage AC/DC power delivery alone under extreme hydrostatic pressure.

The TPU (thermoplastic polyurethane) jacket is specially engineered for prolonged deep-sea immersion. Unlike standard elastomers, this TPU formulation offers exceptional resistance to hydrolysis, cathodic disbondment, and marine biofouling adhesion, while retaining superior abrasion, cut, and impact resistance. Its reliable performance across a wide temperature range (-40°C to +105°C) ensures consistent operation from arctic waters to tropical seas.

Ideal for:

Deep‑sea ROV/AUV power tether for high‑thrust propulsion and manipulator systems

Subsea hydraulic power units (HPUs) and electric actuators

High‑capacity subsea pumps, compressors, and blowers

Offshore drilling equipment and blowout preventer (BOP) control power

Marine renewable energy – tidal turbine and wave energy converter power links

Shipboard heavy‑duty power feeds requiring watertight bulkhead penetration

Any underwater system needing pure 3‑phase or single‑phase high current (up to 35A) without signal integration, in extreme marine environments and without mechanical tension requirements

This cable is dedicated to high‑capacity 3‑phase power transmission under high hydrostatic pressure, eliminating signal conductors and minimizing overall cable diameter for easier subsea handling. It is a preferred solution for marine engineering, deep‑sea mining, underwater propulsion, and offshore energy distribution.
