Low Smoke Zero Halogen (LSZH) — and Then Some

Overview

What Makes a ConductRF Flexible LSZH RF Cable Assembly for Naval/Marine Applications “MarineSafe™”?

MarineSafe™ RF cable assemblies from ConductRF are not simply cables with LSZH jackets—they represent a purpose-curated line of assemblies engineered to protect lives, ensure mission-critical signal integrity, and survive the most demanding shipboard and marine conditions.

Our approach to developing the MarineSafe series began by re-engineering the flexible cable assembly from the outside in, guided by the extreme conditions and safety requirements of enclosed naval environments, where standard materials and assembly techniques often fail.

Jacket Temp Rating

“MarineSafe™ cable assemblies are constructed using materials and designs that meet or exceed the flame resistance, low smoke output, and halogen-free emission requirements of MIL-DTL-24643, MIL-STD-810, and IEC 60332/60754/61034, making them ideal for use aboard naval vessels, submarines, and other enclosed or crewed defense platforms.”

Applications

Where MarineSafe™ Cables Excel

MarineSafe™ flexible LSZH RF cable assemblies were purpose-built to support mission-critical systems aboard ships, submarines, and marine platforms—where performance failure can mean communication breakdown, system vulnerability, or even loss of life.

Here’s where they’re commonly deployed:

Shipboard Communication Systems
Voice, data, and encrypted communication lines between bridge, CIC (Combat Information Center), and engineering compartments.
Backbone connectivity for SATCOM terminals, UHF/VHF transceivers, and network routers.
Radar and Navigation Systems
High-frequency interconnects in surface search radar (e.g., AN/SPS series)
Signal lines for GPS, sonar uplinks, and inertial navigation aids.
RF transmission in phased array systems and rotating dish radars.
Electronic Warfare and Defense Systems
Cables carrying signals to and from jammers, RF sensors, and electronic countermeasure arrays.
Used in below-deck processing units and above-deck emitter heads.
Bridge Control and Monitoring Systems
EMI-shielded links for systems that control engines, ballast, and steering.
Redundant signal paths to ensure safe operation even during localized system failure or damage.
Maintenance Bays and Technical Racks
Used in test environments and portable RF kits for diagnostics.
