Cable tray diversion is achieved using dividers or barrier systems to separate and organize cables within a tray, preventing interference and simplifying maintenance.

Purpose of Cable Tray Diversion

Cable tray dividers are used to separate different types of cables, such as power and data lines, within a single tray. This helps prevent electromagnetic interference (EMI), reduces the risk of damage, and makes maintenance easier by keeping cables organized and accessible . Diversion also allows for efficient routing in complex installations like data centers, industrial facilities, and commercial buildings .

Types of Cable Tray Dividers

1. Straight Dividers: Simple strips or panels that split a tray into two or more pathways for different cable types .
2. Barrier Dividers: Designed to provide an EMI barrier between power and data cables, often used in sensitive electronic environments .
3. Customizable Dividers: Snap-on or field-fabricated dividers that can be cut or adjusted to fit curves, turns, or varying tray widths .

Materials and Finishes

Cable tray dividers are available in stainless steel, pre-galvanized steel, or zinc-plated steel, depending on environmental requirements. Stainless steel is preferred in washdown or corrosive environments, while galvanized or zinc-plated steel is suitable for general indoor or industrial use .

Installation Guidelines

• Dividers are typically attached using push pins, screws, or snap-on mechanisms depending on the tray system .
• For wire mesh trays, support should be added every five feet to maintain structural integrity .
• When possible, power and data cables should be run in separate trays; if not, dividers provide the necessary separation to reduce EMI .
• Dividers can be field-fabricated with tin snips to accommodate changes in radius or level .

Applications

Cable tray diversion is widely used in:

• Data centers and network closets for organized cable management .
• Industrial and commercial buildings including hospitals, schools, and convention centers .
• Environments requiring EMI protection, such as control rooms or sensitive electronic installations .

Benefits

• Reduces cable congestion and tangling.
• Provides EMI protection between power and data lines.
• Simplifies maintenance and troubleshooting.
• Enhances safety and compliance with electrical standards. By selecting the appropriate divider type, material, and installation method, cable tray diversion ensures a well-organized, safe, and efficient cable management system .
