Hybrid Coaxial Armoured Cable for Subsea Systems
TEBAOFLEX Hybrid Coaxial Armoured Cable is a custom subsea cable solution that combines coaxial signal transmission with additional power, control, signal or optical elements inside a mechanically protected armoured construction. It is designed for marine towing, subsea equipment, offshore survey, sonar and underwater systems that require more than one transmission function in a single cable.
The hybrid cable is engineered around the connected equipment, signal impedance, electrical load, operating depth, tensile requirement, bending conditions and deployment method. Coaxial and non-coaxial elements can be arranged together with copper shielding, protective layers and preformed galvanized steel wire armour.
Key Features
- Hybrid construction combining coaxial transmission with power, control or data elements.
- Double-layer preformed galvanized steel wire armour for mechanical protection and tensile performance.
- Coaxial impedance options can be selected according to the connected signal system.
- Suitable for marine towing, subsea survey, sonar and underwater instrumentation.
- Custom core arrangement, cable diameter, strength, jacket and termination design.
- Designed for controlled bending and repeated deployment or recovery cycles.
Hybrid Cable Construction
| Layer or element | Typical design function |
|---|---|
| Coaxial core | High-frequency signal, sonar, video, telemetry or data transmission. |
| Power conductors | Electrical supply for subsea sensors, instruments, tools or remote equipment. |
| Control and signal cores | Low-voltage control, instrumentation and monitoring circuits. |
| Shielding | Copper braid, spiral shield or foil and tape systems selected for signal protection. |
| Inner sheath and tape | Core protection, separation and construction stability. |
| Armour | Preformed galvanized steel wire armour selected for tensile load and crush resistance. |
| Outer jacket | Marine-grade protection selected for water, abrasion, oil, corrosion and environmental exposure. |
Applications
- Subsea sonar and acoustic systems.
- Marine survey and geophysical towing equipment.
- ROV and underwater robotic systems.
- Offshore inspection and monitoring equipment.
- Oceanographic sensors and underwater instrumentation.
- Subsea targets, cameras and equipment requiring combined signal and power transmission.
Selection Requirements
Before ordering, confirm the coaxial impedance, operating frequency, attenuation limit, capacitance, voltage rating, power load, conductor count, fibre-optic requirements, operating depth, towing load, cable length, minimum bending radius and termination arrangement.
TEBAOFLEX can review the complete duty profile and recommend the appropriate hybrid construction. The cable should be evaluated together with the winch, towing body, connectors and deployment system.
