Tray cable shields protect against EMI. Cable tray systems are engineered support structures designed to route, support, and protect insulated electrical cables used for power distribution, control, instrumentation, and communication. Unlike conduit systems, cable trays allow cables to be laid in bundles, improving accessibility, heat. Shielding capability refers to how well a cable tray blocks electromagnetic interference (EMI) from surrounding electrical sources. SHIELDED TRAY CABLE Selecting shielded or. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Cable shielding is essential to protect data and power transmission from interference, especially in environments with high levels of electromagnetic interference (EMI).
