Introduction: Ensuring Signal Integrity at Sea
Feichun FM2XCH MULTI CORE Cables are specifically engineered to ensure reliable control and signal transmission in demanding marine environments. Designed for use in electromechanical and electronic equipment, these cables are suitable for both interior applications and open-deck installations aboard ships.
With features like twisted pairs for signal integrity and an overall screen for effective electromagnetic interference (EMI) mitigation, the FM2XCH MULTI CORE cables ensure flawless operation even under challenging conditions.
Built to withstand harsh environments, these cables offer robust performance with a minimum recommended installation temperature of -15°C, making them an ideal choice for marine installations.
This guide aims to provide a comprehensive understanding of the technical specifications, installation guidelines, best practices, and the problems this cable solves for customers.
The Challenges of Marine Cabling and the FM2XCH Solution
1. Electromagnetic Interference (EMI)
Marine vessels host numerous sources of EMI, such as radars, radios, and communication systems. EMI can disrupt sensitive control and signal circuits, potentially leading to operational failures.
The overall copper screen in FM2XCH MULTI CORE cables effectively minimizes such interference, ensuring stable and reliable signal transmission.
2. Harsh Environmental Conditions
Marine cables face challenges like salt spray, UV exposure, extreme temperatures, and mechanical stresses.
The FM2XCH cable’s halogen-free, flame-retardant outer sheath and XLPE insulation protect it from these conditions, ensuring long-term durability.
3. Installation Constraints
Cables often need to be routed through confined spaces, requiring flexibility and precise handling.
With a minimum bending radius of 6xD, FM2XCH cables are designed to adapt to tight installations without compromising their structural integrity.

Installation Guidelines and Best Practices
1. Minimum Installation Temperature
FM2XCH cables should not be installed below -15°C to avoid sheath cracking or reduced flexibility. If installation in colder temperatures is unavoidable, pre-warming the cable is recommended.
2. Cable Routing
- Avoid EMI Sources: Ensure the cable is routed away from sources of electromagnetic interference to maintain signal quality.
- Use of Supports: Install the cable using appropriate trays and conduits to secure it against mechanical stress and vibration.
3. Bending Radius
Adhere to the minimum bending radius of 6xD to prevent conductor damage and ensure optimal signal transmission.
4. Termination and Grounding
- Use connectors rated for marine environments, such as IP-rated connectors.
- Properly ground the copper screen to enhance EMI shielding effectiveness.
Troubleshooting and Maintenance
Common Issues and Solutions
| Issue | Cause | Solution |
|---|---|---|
| Signal Loss | Damaged conductors or poor grounding | Inspect for physical damage and verify proper grounding of the screen. |
| EMI Disruption | Inadequate shielding or routing near EMI | Ensure screen continuity and maintain separation from EMI sources. |
| Sheath Damage | Cuts, abrasions, or cracking | Promptly repair or replace to prevent water ingress and insulation breakdown. |
| Improper Core Identification | Mislabeling or confusion during installation | Recheck core identification before termination. |
