18-degree bend in cable tray

An 18-degree cable tray bend is a specialized fitting used to change the direction of a cable tray run by 18 degrees, typically available in adjustable or pre-fabricated forms for horizontal or vertical applications.

Overview

An 18-degree cable tray bend allows for gradual directional changes in cable tray systems, reducing stress on cables and maintaining proper bend radius. These bends are commonly used in data centers, industrial facilities, and commercial buildings where precise routing is required. They can be horizontal or vertical, depending on whether the tray changes direction in the same plane or across levels.

Types and Materials

Adjustable Mesh Tray Bends: Systems like Cablobend allow flexible angle adjustments from 0° up to 90°, making it possible to achieve an 18° bend without cutting or custom fabrication. These are ideal for quick installations and prefab efficiency, available in multiple widths and heights with EZ or BL finishes for durability and compliance with RoHS standards.

Pre-

Fabricated Solid or Ladder Tray Bends: Some manufacturers provide solid or ladder-style bends with specific radii. While standard bends are often 45° or 90°, smaller angles like 18° can be achieved using custom or segmented bends that combine multiple smaller sections. Materials: Common materials include aluminum, galvanized steel, and stainless steel, often with protective coatings like Sendzimir galvanization to prevent corrosion and maintain structural integrity.

Installation Considerations

Bend Radius: Ensure the bend radius is sufficient for the cable type to prevent damage. Gradual bends like 18° are preferred for sensitive or high-density cables. Hardware and Fastening: Use manufacturer-supplied clips or brackets to secure the bend to the tray system, maintaining alignment and load support.

Compatibility: Verify that the bend matches the tray width, height, and type (ladder, solid, or wire mesh) to ensure seamless integration.

Applications

Data Centers: Smooth routing of network and power cables with minimal stress. Industrial Facilities: Gradual directional changes in long cable runs to avoid sharp turns. Commercial Buildings: Aesthetic and functional routing in ceilings or walls where precise angles are required.

In summary, an 18-degree cable tray bend can be implemented using adjustable mesh systems or custom pre-fabricated sections, with careful attention to material, radius, and installation hardware to ensure safe and efficient cable management.
