III. Installation Guidelines and Best Practices

 

 

Maximizing Shielding Effectiveness: Installation Best Practices

 

 

Proper installation is essential to ensure the cable’s EMI shielding is effective.

 

 

Cable Handling

 

  • Handle with care to avoid mechanical damage to the screen or outer sheath.

 

  • Use appropriate tools to maintain the cable's integrity.

 

 

Cable Routing

 

 

  • Separation from Power Cables: Maintain adequate distance to minimize interference.

 

 

  • Avoid Sharp Bends: Adhere to the minimum bending radius to protect the shielding.

 

 

Termination and Grounding

 

 

 

  • Use EMC glands and connectors to maintain screen continuity.

 

 

 

  • Properly bond the screen to the ship’s grounding system to ensure effective EMI shielding.

 

 

 

Bonding and Grounding Tips

 

 

 

Step Action
1. Preparation Inspect the grounding system for compatibility with the cable screen.
2. Bonding Connections Use secure, conductive clamps to connect the screen to the grounding system.
3. Testing Perform post-installation tests to confirm effective EMI mitigation.

 

 

IV. Common Challenges and Troubleshooting

 

 

 

Maintaining Shielding Integrity: Troubleshooting Common Issues

 

 

 

 

Screen Damage

 

 

 

 

Causes: Mechanical stress during installation or mishandling.
