Shielding function of cable trays
Placing a layer of foil or braided metal between the tray cable's jacket and conductors substantially reduces EMI effects. The shielding, through its natural electrical properties, attracts, collects, and effectively (when properly grounded) drains off the EMI. How Does EMI Affect Cables? EMI comes from many sources, including:. This layer is called shielding. Its purpose is to collect and drain off electromagnetic interference (EMI) and radio frequency interference (RFI) caused by common mode currents. Basic Structure of Cable Shielding. Shielding works by: Isolating the signal transmitted in the cable: This ensures that the signals inside the cable are protected from external interference.
