Cable tray bends are designed to guide cables around obstacles, changes in direction, or elevations in an electrical system. The scope of this report covers the primary mechanical designs and bend configurations of cable tray systems used in industrial, commercial, and residential environments. The analysis includes structural types (ladder, perforated, wire mesh), specific bend fittings (horizontal and vertical risers). 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. Bending trays allows installers to work around obstacles like walls, beams, or machinery, and to guide cables in the desired direction without needing additional connectors or joints. Available nominal widths are 1. When specifying width, cable ties or other spacing devices may be used to maintain the required air space between cables.
