Methods for Horizontal Relocation of Cable Tray Bends
A horizontal bend in a cable tray allows the tray to change direction horizontally, facilitating flexible routing of cables in various installations.
Overview
A horizontal bend is a fitting used to redirect a cable tray along a horizontal plane, similar to bending piping. It enables the cable tray to navigate around obstacles or change direction without interrupting the cable run . These bends can be manufactured in various angles, commonly 30°, 45°, 60°, and 90°, and can be customized to meet specific installation requirements .
Types and Materials
Horizontal bends are available for different cable tray types, including:
- Ladder type
- Perforated type
- Wire mesh type They can be made from steel, fiberglass, or other materials depending on the system requirements . Some bends are adjustable, allowing fine-tuning of the angle on-site to accommodate complex layouts .
Installation Features
- Pre-drilled fittings: Many horizontal bends come pre-drilled to accept splice plate fasteners, simplifying installation .
- Smooth radius design: Curved rails in the bend reduce friction and make cable pulling easier, preventing damage to cables .
- Screw or bolt connections: Bends can be connected to straight tray sections using screws or bolts, ensuring secure attachment .
Customization
Manufacturers can produce horizontal bends in any size, width, depth, or length to match the cable tray system. This flexibility allows for precise alignment and smooth transitions in horizontal routing . Special requests, such as non-standard angles or adjustable elbows, are often accommodated by factory engineering support .
Practical Considerations
When planning horizontal relocation of cable trays:
- Ensure the bend radius is sufficient for the type and number of cables to prevent excessive bending stress.
- Select the appropriate material and finish for environmental conditions (e.g., corrosion resistance).
- Verify compatibility with the existing tray system and fastening method. Using horizontal bends effectively ensures a safe, organized, and efficient cable routing system while maintaining accessibility for maintenance and future expansion.
