Electrical cable tray bend tools

Cable tray bends can be safely and efficiently created using specialized bolt cutters, wire cutters, and bend calculators to ensure proper radius and structural integrity.Tools for Bending Cable Trays1. Angular Bolt Cutters For wire mesh or basket-type cable trays, angular bolt cutters are recommended. Tools like the WB30BC Angular Blade Offset Bolt Cutter with 24-inch handles allow clean cuts and precise bends without damaging the tray wires. Position the blades perpendicular to the cross wire for optimal results, and avoid center-cut blades to maintain structural integrity .2. Wire Cutters Battery-operated wire cutters, such as the Greenlee cable wire cutter, can make flush cuts on tray wires quickly and safely. These cutters rotate for ease of positioning and automatically retract after cutting, reducing the risk of burrs and improving installation speed .3. Bend Calculators and Software Online tools like the Cable Tray Bend Calculator help determine the minimum bend radius based on cable type and diameter. By entering the cable category (single core, multicore, control, or MV/HV) and the cable diameter, the calculator provides the recommended tray bend radius, ensuring compliance with safe installation practices .4. Pre-Fabricated Fittings Using pre-fabricated bends, tees, and reducers is often the safest and most efficient method. Standard radii (300 mm, 450 mm, 600 mm, 900 mm) are available to match calculated minimum bend requirements, reducing the need for on-site fabrication .Best PracticesAlways ensure the tray bend radius is greater than or equal to the minimum cable bend radius to prevent cable damage .For solid or ladder-type trays, mark the side rails at intervals based on the calculated arc length, cut V-notches, and bend until the gap closes .Use non-metallic banding when handling bundled trays to avoid corrosion or contamination .Follow manufacturer guidelines for material type and finish, as aluminum, stainless steel, and galvanized steel trays may require different handling techniques .By combining proper tools, pre-fabricated fittings, and accurate bend calculations, installers can achieve safe, efficient, and compliant cable tray bends for industrial and commercial electrical installations.
