How to separate the cable tray in Huijue

Separate electrical and instrumentation cable trays by layering, maintaining minimum spacing, and using dividers to prevent interference and ensure safety.

Layered Separation

In Huijue, electrical (power) cable trays should typically be positioned above instrumentation (signal/control) trays. This arrangement minimizes electromagnetic interference (EMI) from high-current power cables affecting sensitive instrumentation cables below. Strong current and high-voltage cables should be kept apart from low-current, low-voltage cables to preserve signal quality and system reliability .

Minimum Spacing

Maintain a minimum vertical and horizontal distance between power and control trays. Industry standards recommend at least 300 mm (12 inches) of separation to reduce EMI. If space constraints prevent this distance, metal partitions or dividers can be installed between trays to provide additional shielding and prevent interference .

Use of Dividers and Partitions

Where cable trays must run close together, installing a solid or perforated metal divider within the tray can separate different types of cables. This is particularly important in areas with dense cabling or high electromagnetic fields. Dividers also help organize cables, maintain proper bend radius, and prevent overcrowding .

Layout and Routing Considerations

• Plan straight and direct pathways for trays to minimize unnecessary bends and junctions, reducing cable length and potential signal loss .
• Ensure accessibility for maintenance and future modifications, keeping adequate clearance from walls, ceilings, and other obstructions .
• Follow manufacturer and industry standards for tray supports, grounding, and bonding to maintain electrical safety .

Practical Tips

• Use ladder, perforated, or solid-bottom trays depending on cable type and environmental conditions.
• Maintain proper cable fill ratios to avoid overcrowding, which can compromise performance.
• Ground and bond trays at regular intervals to ensure safety and continuity . By following these principles, Huijue installations can achieve safe, organized, and interference-free cable tray systems that comply with industry standards and facilitate future maintenance.
