How can I prevent interference if I have both power lines and coaxial cables in the same project area?

2025-08-12

This is a critical consideration in any project involving both power and data. The key is to physically separate the two types of lines. We advise following these best practices to minimize electromagnetic interference (EMI) and radio frequency interference (RFI):

  1. Maintain Separation: Whenever possible, keep a minimum distance of at least 6 inches (15 cm) between power cables and coaxial cables.

  2. Separate Conduits: Never run power cables and coaxial cables in the same conduit or cable tray.

  3. Cross at Right Angles: If the lines must cross, ensure they do so at a 90-degree angle to minimize the area of interaction between their electromagnetic fields.

  4. Use Quality Shielding: Ensure the coaxial cables are of high quality with effective shielding (braided or foil) to provide better protection against external fields.

Our commitment to safety and quality extends to providing the right equipment for the right application, helping our clients implement these best practices on-site.
