Trough-type cable trays are bent using controlled mechanical methods to maintain structural integrity, proper cable support, and safe installation.

Overview of Trough-

Type Cable TraysTrough-type cable trays are designed for larger cable diameters or multiple cable gangs, providing robust support and protection. They typically have depths ranging from 50mm to 100mm and are constructed from materials such as mild steel, aluminum, or stainless steel with thicknesses from 1. 0mm up to 2.

3mm depending on duty requirements. The trays are often perforated to allow ventilation and reduce weight, and all edges are smoothed to prevent cable damage. Bending ProcessPre-Bending ConsiderationsEnsure the tray is free from sharp edges and all perforations are accounted for.

Verify the material type and thickness, as steel, aluminum, and stainless steel have different bending tolerances. Determine the required bend angle and radius, keeping in mind the minimum bend radius for cables to prevent insulation damage. Mechanical BendingTrough-type trays are typically bent four times along their cross-section to form the trough shape, compared to channel trays which are bent twice.

Bending is performed using press brakes, rollers, or specialized bending machines to ensure uniformity and avoid deformation. For perforated trays, bends should occur in unperforated sections when possible, and cut edges should be treated with zinc-rich paint to prevent corrosion.

Bending Handling

After bending, all edges must be smoothed to prevent cable insulation damage and ensure installer safety. Bends should maintain the structural integrity of the tray, avoiding cracks or excessive thinning of the material. Pre-fabricated bends and turns are often available as stocked items, minimizing on-site fabrication and ensuring precision.

Installation Considerations

Support brackets should be evenly spaced to limit deflection to 1/175 of the span. Covers and snap-in components should fit precisely to maintain cable protection and aesthetics. Ventilated designs help reduce heat buildup and prevent moisture accumulation within the tray.

By following these steps, trough-type cable trays can be bent and installed safely, providing durable, professional cable management while protecting cables from mechanical stress and maintaining compliance with installation standards.
