How to turn a cable tray without using bends

Cable trays can be installed in straight runs without bends by planning the layout, using offsets or gradual angles, and connecting modular straight sections.

Planning Straight Cable Tray Runs

To avoid bends, start by carefully planning the cable tray route. Identify obstacles such as pillars, walls, or equipment that may require deviation. Instead of sharp bends, you can use parallel offsets or gradual angled sections to navigate around obstacles while keeping the tray essentially straight.

This approach reduces stress on cables and simplifies installation.

Using Modular Straight Sections

Most cable trays are available in standard straight sections that can be bolted together. By combining these sections, you can create long, continuous runs without bends. For wire mesh or ventilated trays, straight sections can be cut to length on-site using a bolt cutter or saw, ensuring a clean, straight installation.

Rubber end caps can protect cut edges and maintain safety.

Creating Offsets Instead of Bends

When a straight path is interrupted, you can create a parallel offset rather than a bend. Measure the required offset distance and divide it over multiple straight sections to maintain a gentle deviation. For example, if a 350mm offset is needed in a 600mm wide tray, you can distribute the offset over several sections to avoid sharp angles.

This method keeps the tray straight while navigating around obstacles.

Maintaining Cable Protection

Even without bends, it is important to maintain proper spacing and support. Use appropriate rung spacing (typically 150–230mm) and secure the tray to supports to prevent sagging or cable damage. Solid or ventilated bottoms can be chosen depending on the type of cables and environmental conditions.

Summary

Plan the route to minimize obstacles. Use straight modular sections and cut to length as needed. Employ parallel offsets or gradual angles instead of sharp bends.

Ensure proper support and spacing to protect cables. By following these steps, you can install cable trays in straight runs without bends while maintaining safety, cable integrity, and ease of installation.
