TEBAOFLEX coaxial armoured tow cable for subsea and marine equipment

Choose by system duty, not by name alone

Use this page to narrow the cable route before comparing a product model or submitting a specification.

Start with the equipment

Identify the machine, circuit function, route and the consequence of cable failure at that location.

Define the complete duty

State voltage or transmission needs together with movement, bending, load, fluids, temperature and installation exposure.

Confirm one construction

Review conductor or fibre elements, screens, reinforcement, sheath, termination, standards and documentation as one schedule.

Match the cable to the equipment and route

Start with the equipment mission and deployment method, then choose the cable family that carries the required services and mechanical duty.

ROV and AUV systems

Power, control, video, Ethernet or fibre services matched to tether handling, vehicle interface and termination constraints.

View a compact power-and-fibre route

Towed sonar and arrays

Load-bearing coaxial, paired-signal or hybrid routes for sonar bodies, hydrophones and marine survey equipment.

View a coaxial tow-cable route

Oceanographic instruments

Winch-deployed cables for CTD systems, cameras, sensors, samplers and research-vessel equipment.

View an instrumentation route

Underwater video and telemetry

Coaxial transmission, power, control cores or screened pairs combined where separate cables complicate deployment and termination.

View a hybrid coaxial route

Optical monitoring and sensing

Load-bearing fibre for high-bandwidth underwater links that do not need copper power conductors.

View a pure optical route

Deepwater hybrid systems

Electro-optical and mechanically reinforced routes reviewed around load, handling, waterblocking and termination.

View a deepwater high-load route

Define the conditions that control cable life

The costly failure is rarely described by the product name. Separate signal compatibility, movement, environment and interface risks before choosing a construction.

Signal mismatch

A nominal cable type is not enough. Define coaxial impedance and frequency, allowable attenuation, or fibre type, count and wavelength together with cable length.

Fatigue and load-path failure

A static underwater cable can fail on a winch. State whether the route is suspended, reeled, towed or repeatedly deployed, with load and bend geometry.

Heat, water and material ageing

Temperature, water migration, hydrolysis, abrasion, chemicals and corrosion determine which insulation, sheath, waterblocking and armour route is credible.

Connector and termination bottlenecks

Diameter, bend radius, armour anchoring, sealing, moulding and available equipment space can eliminate an otherwise suitable electrical or optical design.

Compare suitable cable-family routes

Use the limiting engineering problem to choose a family first. The product routes below then separate impedance, circuit count, temperature, optical power integration and load capacity.

Impedance plus towing load

For a single 39-45 Ohm or 50 Ohm coaxial path that must also carry deployment load. Match the equipment interface before comparing diameter and strength.

Start with 39-45 Ohm coaxial routes

Heat, sensor circuits and compact envelopes

For elevated-temperature conductors or compact underwater sensing and control circuits where material, core count and handling duty are the limiting choices.

Start with instrumentation routes

Coax, power and control in one interface

For sonar, video or telemetry systems that need coaxial transmission plus electrical services without separate tow-cable terminations.

View hybrid coaxial constructions

Optical data, with or without power

Choose pure optical cable when copper power is unnecessary, compact electro-optical cable when space controls, or a high-load route for demanding deployment duty.

Start with the pure optical route

From operating data to an agreed cable schedule

The process keeps equipment, cable construction, interfaces and documentation aligned before production.

Share the operating duty

Provide the equipment, electrical or transmission services, movement, route and environment.

Review the cable route

Separate circuit functions and compare the constructions that fit the operating duty.

Confirm the technical schedule

Agree the construction, dimensions, interfaces, standards, inspection stages and document list.

Manufacture and inspect

Production, marking, packing and agreed inspection follow the confirmed order specification.

Frequently asked questions

Short answers to common questions before a project-specific cable review.

What is the difference between a subsea equipment cable and a submarine infrastructure cable?

This page addresses cables for equipment, instruments, towing, deployment and compact power or data systems. Long-distance submarine power and telecommunications infrastructure has different installation, jointing and system requirements.

When should a subsea equipment cable be armoured?

Armour is considered when the cable must carry deployment or towing load, needs mechanical protection, or must transfer load into a termination. Armour material, lay, corrosion exposure, bending and anchoring must be reviewed together.

Can power, coaxial signal and fibre be combined?

Yes, a hybrid construction can combine services when the electrical, optical, screening, heat, diameter, load and termination requirements are engineered as one cable system.

Can a static underwater cable be used on a winch?

Not without confirming the dynamic duty. Reeling introduces repeated bending, drum pressure, tension, layer interaction and handling conditions that a static construction may not be designed to withstand.
