* Use Cable Ties or Separators: Use cable ties or separators to maintain spacing between cables and prevent tangling. In my experience as a contractor and through conversations with field installers, I've determined that the most common cable tray technologies available are as follows: Wire basket tray Pros: From the installer, designer and owner's point of view, this system is becoming the preferred tray for low. 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 tray systems have become an essential component in the infrastructure of modern commercial buildings, smart offices, data centers, and various industrial facilities. These systems provide an efficient and adaptable solution for managing a wide range of cables, including power cables, control.
