Bending (Cable Tray Bends)

Function: Designed to alter the direction of cable tray runs smoothly and safely, accommodating changes in both horizontal and vertical pathways while maintaining cable integrity and system support.

Key Types & Applications:

1. Horizontal Bends:

   • 90° Bend: For perpendicular turns within the same horizontal plane (e.g., corners).

   • 45° Bend / 30° Bend: For gentler directional changes or compound angles in horizontal layouts.

   • Application: Routing trays around obstacles, building corners, or equipment within a floor/level.

2. Vertical Bends (Risers/Drops):

   • 90° Vertical Bend (Riser/Drop): For transitioning a tray run vertically upward (rise) or downward (drop) at a right angle.

   • Offset Bend (Vertical or Horizontal): For shifting the tray run parallel to its original path while changing elevation (vertical offset) or lateral position (horizontal offset). Essential for bypassing pipes, ducts, or structural elements without changing the overall direction.

   • Application: Moving cable trays between floors, connecting to equipment at different heights, navigating under beams or pipes.

3. Customizable Angles: Available in standard angles (30°, 45°, 60°, 90°) and often configurable for site-specific requirements.

Material Compatibility: Manufactured to match the material and specifications of the main cable tray system (e.g., Steel, Stainless Steel, Aluminum, Fiberglass/Composite).

Key Advantages:

• Maintains System Integrity: Ensures continuous support and protection for cables during direction changes.

• Prevents Cable Damage: Smooth radius bends (especially in molded composite systems) minimize stress, friction, and potential damage to cable jackets during installation and operation.

• Preserves Load Capacity: Engineered to maintain the structural strength and load rating of the straight tray sections.

• Ensures Safety & Compliance: Facilitates proper cable bend radius adherence (critical for fiber optics and power cables) and supports compliance with electrical codes (e.g., NEC, IEC).

• Optimized Installation: Pre-fabricated bends save significant field labor time compared to custom field fabrication.

Critical Specifications:

• Bend Angle (e.g., 30°, 45°, 90°)

• Inside Radius / Outside Radius

• Tray Width & Side Height Compatibility

• Material & Finish (e.g., Galvanized Steel, 316L SS, FRP Composite)

• Load Rating (Light, Medium, Heavy, Extra Heavy Duty)

• Compliance Standards (e.g., NEMA VE 1, IEC 61537)

Integration: Seamlessly connects to straight cable tray sections (Ladder, Channel, Solid Bottom, Wire Mesh) using standard splice plates, bolts, or system-specific connectors.

Purpose: Bends are essential components for creating efficient, adaptable, and code-compliant cable tray pathways in complex industrial, commercial, and infrastructure environments.
