PDK81301 4x2.5 + 3x2x0.2 + 1x2x0.2 Multi-Core Subsea Power Cable

Product introduction

This product is a combined power, signal and fiber watertight (subsea) cable, designed for complex underwater systems that need high-current power supply, multi-channel signal control and optical data transmission at the same time, such as ROVs, AUVs, subsea production systems and underwater scientific instruments. It integrates high-voltage power transmission, twisted-pair signal cores and fiber units in a fully sealed construction, providing versatility without compromising watertight integrity.

The cable uses a PUR (polyether polyurethane) outer sheath with high abrasion resistance, good low-temperature flexibility and resistance to oil, grease and seawater, ensuring long-term durability in harsh subsea environments.

Ideally suited to:

ROVs and AUVs that need power, control and high-bandwidth data in a single tether

Subsea production systems and offshore oil and gas platforms

Underwater scientific observatories and real-time monitoring networks

Sonar systems, acoustic arrays and seabed instruments

Marine renewable energy systems and subsea power distribution

Any subsea equipment that requires integrated power, multi-channel signal and fiber transmission under extreme marine conditions

The cable is designed to carry high-current power together with sensitive control signals and high-speed fiber data without the need for several separate cables. It suits subsea robotics, deep-sea exploration, marine engineering and underwater defense systems.
