The Challenges of Marine Cabling and the FM2XH Solution
Designed to Withstand the Seas: Addressing Marine Cabling Challenges
Marine cables face several obstacles, including:
Harsh Environmental Conditions
Solution: The FM2XH cable’s halogen-free, flame-retardant outer sheath resists UV exposure, moisture, and mechanical wear, ensuring long-lasting durability.
Salt Spray and Humidity: Accelerates corrosion and degrades materials.
UV Radiation: Leads to cracking and embrittlement of non-resistant materials.
Temperature Fluctuations: Ranges from -40°C to +90°C in various operational zones.
Mechanical Stress and Vibration: Frequent movement can weaken connections over time.
Electromagnetic Interference (EMI)
Solution: The cable’s overall copper braided screen, with 90% coverage, effectively shields sensitive circuits from external interference.
Sources: Shipboard systems such as radar, communication devices, and electronic control units can generate significant EMI.
Impact: EMI can distort or disrupt signal transmission, leading to equipment malfunctions.
Installation Constraints
Solution: The FM2XH cable offers flexible routing capabilities with a minimum bending radius of 4xD (for D ≤ 25 mm) or 6xD (for D > 25 mm).
Tight spaces and complex layouts make routing and installation challenging.
Bending flexibility is essential to navigate confined environments.

Installation Guidelines and Best Practices
Ensuring Reliable Performance: Installation and Handling
Cable Routing and Handling
- Avoid sharp bends; adhere to the bending radius guidelines of 4xD or 6xD, depending on the cable diameter.
- Use cable trays and conduits to secure the installation.
- Keep signal cables separated from power cables to minimize EMI risks.
Minimum Installation Temperature
- Cables must not be installed below -15°C. If unavoidable, warm the cable in a controlled environment before installation.
Termination and Grounding
- Use IP-rated connectors and EMC glands for marine environments.
- Ground the cable screen at one or both ends, depending on system requirements.
Troubleshooting and Maintenance
Maintaining Reliability: Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Signal degradation | Damaged insulation or improper grounding. | Inspect and repair as needed. |
| EMI interference | Poor screen continuity or inadequate separation. | Verify grounding and cable placement. |
| Sheath damage | Abrasion or UV exposure. | Replace the cable or add protective coverings. |
