Cable tray division

Cable tray division involves using dividers or barrier systems to separate different types of cables within a single tray, ensuring organization, safety, and reduced electromagnetic interference.

Purpose of Cable Tray Division

Cable tray dividers are used to organize and separate cables within a tray, particularly when power, data, and control cables share the same pathway. This separation helps prevent electromagnetic interference (EMI), reduces the risk of damage, and simplifies maintenance and future expansions . Dividers also maintain a clean and systematic layout, improving accessibility and safety .

Types of Cable Tray Dividers

1. Straight Divider Strips: Simple strips installed along the tray to create separate channels for different cables. They are available in various widths and materials, including pre-galvanized steel and stainless steel for washdown or industrial environments .
2. Snap Track Dividers: These attach to Snap Track trays using patented push pins and can be field-fabricated to fit curves or changes in elevation. They are designed to provide EMI barriers between power and data cables .
3. Divider Kits: Complete kits include hardware and pre-cut strips for easy installation in basket or wire mesh trays. They are often adjustable to accommodate different cable sizes and tray widths .

Installation Considerations

• Separate Trays When Possible: Ideally, power and data cables should run in separate trays to minimize EMI .
• Support and Spacing: Dividers should be supported at regular intervals, typically every five feet, to maintain structural integrity in wire mesh trays .
• Material Selection: Choose materials compatible with the environment, such as stainless steel for corrosive or washdown areas .
• Custom Fabrication: Some dividers can be cut or bent on-site to fit bends, tees, or risers in the tray system .

Benefits

• Reduces electromagnetic interference between power and sensitive data cables.
• Improves cable organization and accessibility for maintenance.
• Enhances safety by preventing cable entanglement and damage.
• Supports future expansion by providing clear separation paths for additional cables. Cable tray division is an essential aspect of modern cable management, particularly in industrial, commercial, and data center environments, ensuring both operational efficiency and compliance with electrical standards .
