This product is a hybrid power-and-signal watertight (submersible) cable, specifically engineered for underwater systems that require both moderate power delivery and multiple independent signal circuits (such as subsea cameras, sonar heads, underwater sensors, and small ROV control umbilical). It integrates two 1.0 mm² power cores with two twisted-pair signal cores (2×2×0.2 mm²) within a single compact jacket. The cable deliberately adopts dual insulation materials – XLPE for the power cores and PE for the signal cores – to optimize electrical performance for each function while maintaining outstanding watertight integrity.

The PUR (polyrther urethane) outer jacket provides exceptional abrasion resistance, low-temperature flexibility, and long-term resistance to seawater, oils, and marine growth. This jacket, combined with a fully water-sealed core assembly, ensures zero leakage under continuous high hydrostatic pressure (up to 1000m depth) without relying on tensile strength design.
This intentional material differentiation ensures that the power cores can safely carry higher current without overheating, while the signal cores maintain clean, low‑loss transmission even in the presence of nearby power conductors.
Ideal for:
Subsea cameras and LED lighting systems (power + video control signals)
Sonar transducers and acoustic positioning beacons (low‑noise signal + power)
Underwater sensors (pressure, temperature, turbidity, conductivity) requiring separate power and analog outputs
Small ROVs and AUVs where weight and diameter are critical
Scientific marine instruments and data loggers
Any underwater equipment needing two independent power conductors plus two twisted signal pairs with optimized insulation materials for each function, without mechanical tension requirements
This cable leverages the best of both insulation worlds: XLPE for robust, heat‑resistant power delivery and PE for low‑loss, high‑integrity signal transmission – all within a single watertight PUR jacket. It is an ideal solution for marine engineering, subsea instrumentation, underwater surveillance, and oceanographic research.
