  • Add shielding inside the cable tray

    Add shielding inside the cable tray

    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. 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. How Does EMI Affect Cables? EMI comes from many sources, including:. In layman's terms, a shielded tray cable is a type of electrical cable developed for installations with moderate to high ambient EMI (Electromagnetic Interference). This specialized cable serves as the bridge of safe and reliable transmission of power, control, and communication signals. It is a versatile option for various types of installations. When common mode current is generated through a copper conductor, EMI is created naturally by the copper's electrical.
