You can add a partition in a cable tray bend by using a divider panel or fabricating a custom partition, ensuring it is securely fastened to maintain cable separation and structural integrity.

Methods for Adding a Partition

1. Using Pre-Made Divider Panels: Some cable tray systems, like the ET range or wire basket trays, allow the installation of built-in or bolt-on partitions. These dividers can be inserted along the tray length, including bends, to separate cable types or voltage classes. Ensure the divider is compatible with the tray width and bend radius to avoid interference with cable routing . 2. Fabricating a Custom Partition: For wire mesh or ET-style trays without pre-made dividers, you can cut a sheet of metal or rigid plastic to fit the bend. The partition should follow the curve of the bend and be attached using:

• Splice plates and bolts for ET trays, ensuring smooth heads face inward to prevent cable damage .
• Push-on or bolt-on splices for wire mesh trays, which secure the partition to the tray mesh without compromising structural integrity . 3. Installation Tips:
• Always measure and mark the bend area before cutting or attaching the partition to ensure proper alignment .
• Secure the partition at multiple points along the bend to prevent movement under cable load.
• Maintain the minimum bend radius recommended for the cables to avoid stress or damage.
• For ET trays, use hold-down units or TX brackets if the partition intersects with a fabricated tee or cross . 4. Safety and Compliance:
• Ensure the partition does not reduce the tray's load capacity below the manufacturer's specifications .
• Follow relevant standards such as IEC 61537 for cable tray installation and load distribution .
• Wear appropriate safety gear when cutting or bending tray materials. By following these methods, you can effectively add a partition in the middle of a cable tray bend, maintaining cable separation, structural stability, and compliance with installation standards.
