Hybrid Coaxial Power & Signal Tow Cable
Hybrid Coaxial Power & Signal Tow Cable brings 5 selectable construction options together for sonar, video, telemetry and towed-system engineers. Compare the complete signal, electrical and mechanical requirement before choosing a configuration.
- Selection focus: compare coaxial, power, control and screened-pair combinations in one load-bearing cable
- Available configurations: 5
- Mechanical inputs: cable length, working load, drum, sheave, routing and deployment cycle
- Quotation inputs: services, environment, termination, quantity and required inspection documents
Hybrid Coaxial Power & Signal Tow Cable selection overview
The Hybrid Coaxial Power & Signal Tow Cable gives sonar, video, telemetry and towed-system engineers one clear route for comparing 5 available constructions. It is designed to compare coaxial, power, control and screened-pair combinations in one load-bearing cable. Keeping the options in one product group makes it easier to compare signal architecture, conductor or fibre content, armour, diameter, mechanical load and bend geometry without switching between separate product pages.
Selection starts with the equipment interface: define voltage and current, signal type and frequency, coaxial impedance and allowable attenuation, or fibre type, count and wavelength as applicable. Then define whether the cable will be static, suspended, reeled, towed or repeatedly deployed. Cable length, working load, breaking-load criterion, drum and sheave dimensions, temperature, water environment, abrasion, buoyancy and the connector or moulded termination must be reviewed as one system.
- Compare: construction, transmission values, outside diameter, load and bend data shown for each option.
- Confirm: the complete service combination and the operating values that apply at the required cable length.
- Specify: inspection stages, test methods, acceptance values, marking and documentation in the quotation.

Hybrid Coaxial Power & Signal Tow Cable construction options
Compare the complete layer sequence for each option. Conductor or fibre elements, insulation, screening, fillers, bedding, strength members, armour and outer sheath are selected together to suit the transmission and deployment duty.| Configuration | Construction |
|---|---|
| RG11 coax plus four power cores | 1 × RG11 coax + 4 × 2.50 mm²; hydrolysis/UV-resistant PUR; two contra-helical armour layers |
| Three 30 Ω coaxes plus three control cores | 3 × 30 Ω coax + 3 × 22 AWG; HDPE; two preformed galvanized steel armour layers |
| 74 Ω coax plus three screened pairs | 1 × 74 Ω coax + 3 × 2 × 1.00 mm²; PUR; preformed galvanized steel armour |
| Four 35 Ω coaxes plus four control cores | 4 × 35 Ω coax + 4 × 22 AWG; silicone waterblocking; two armour layers |
| 74 Ω coax plus four individually screened pairs | 1 × 74 Ω coax + 4 × 2 × 1.00 mm² screened pairs; PUR; galvanized steel armour |
Construction selection
Armour material and lay, sheath material, waterblocking, screening and fibre protection are matched to corrosion exposure, abrasion, repeated bending, handling load and termination design. The armour anchoring and connector or moulded transition are reviewed with the cable because they control how load and water sealing are transferred into the equipment.Applications for Hybrid Coaxial Power & Signal Tow Cable
This product group supports sonar, video, telemetry and towed-system engineers where transmission performance and mechanical deployment duty must be selected together.- Towed sonar, video and telemetry systems combining coaxial transmission with power, control cores or screened pairs.
- Projects seeking one cable/termination interface instead of separate coaxial and electrical cables.
- The service combination must be reviewed for impedance, screening, voltage drop, heat, diameter, bending and armour load.
Information needed for selection
Provide the equipment, cable length, service voltages or signals, load criterion, winch and sheave dimensions, deployment method, water environment, temperature, buoyancy target, connector or moulding interface and required inspection documents.Hybrid Coaxial Power & Signal Tow Cable specifications

Using the values
Breaking load is not the normal operating load. Bend values must match drums, sheaves, guides and connector exits. A voltage entry that includes a duration is a dielectric test value rather than a continuous rated voltage. Confirm the applicable operating and acceptance values in the quotation.Standards and test references
The applicable references are selected for the confirmed cable construction and project duty. They provide a framework for engineering and inspection rather than a one-size-fits-all cable designation.- IEC 61196-1: Coaxial-element definitions, design requirements and test-method framework.
- IEC 61196-1-100: General conditions for electrical tests on coaxial communication elements.
- IEC 60228: Conductor resistance and conductor-class reference for separately specified insulated copper power or control cores.
- Project test plan: Coordinates coaxial performance, conductor tests, screening, voltage drop, tensile load, bending, water exposure and completed-cable acceptance.
