Proper cable tray bending and cutting ensures safe installation, maintains structural integrity, and prevents damage to cables.

Cutting Cable Trays

When cutting cable trays, it is essential to follow safety and precision guidelines: Tools: Use a band saw with a blade suitable for the tray material and thickness to minimize burrs and swarf. For thin metal trays, a band saw is preferred over grinders to reduce sparks and overheating. Safety: Always wear Kevlar gloves, eye protection, headgear, and appropriate footwear.

Sharp edges are common after cutting, so handle with care. Edge Finishing: Remove any burrs or sharp edges after cutting to prevent injury and protect cables during installation. Planning Cuts: Follow manufacturer guidelines for optimal cutting lengths and intervals, especially in modular systems, to ensure proper fit and alignment.

Bending Cable Trays

Bending cable trays allows for directional changes and level adjustments: Bend Radius: Maintain the minimum bend radius recommended for the cables being installed to avoid damage. For most power and instrumentation cables, gradual bends are preferred. Fabrication: Bends can be fabricated on-site using bending tools or pre-fabricated fittings such as elbows, tees, and sweeps.

Support: Ensure that bends are properly supported to prevent sagging or stress on the tray and cables. Material Considerations: Aluminum trays are easier to bend but require attention to avoid cracking, while steel trays may need mechanical bending tools.

Installation Best Practices

Modular Systems: Use modular tray systems to simplify bending and cutting, allowing for easier adjustments and 3D modeling in plant design software. Spacing and Support: Maintain recommended rung spacing (150–230 mm) and support intervals to ensure structural integrity. Avoid Overloading: Do not use trays as walkways or for supporting personnel; they are designed to carry cables and associated equipment only.

Documentation: Follow manufacturer installation guides for specific tray types, such as Cablofil or NEXTFRAME®, to ensure proper use of accessories and fittings. By adhering to these guidelines, installers can achieve safe, efficient, and durable cable tray installations while minimizing the risk of injury or cable damage.
