How to use the accessories for mesh cable trays

Mesh cable tray accessories should be installed according to manufacturer guidelines, ensuring proper support, secure connections, and correct handling of bends, joints, and couplers.

Selecting and Preparing Accessories

Choose accessories compatible with your mesh cable tray type, such as couplers, bends, reducers, and supports. Ensure all components are corrosion-protected according to the environment, using zinc-coated, Geomet®, or resin-coated finishes for durability and compliance with standards like IEC 61537 and NEMA VE-1. Verify that the accessories match the tray width and load requirements to maintain safe working loads.

Installation Steps

Plan the Layout: Map the cable path, including entry/exit points, bends, and junctions. Consider obstacles like beams, HVAC ducts, or walls. Support Placement: Space supports according to tray type and load, typically every 1.

5–2 meters for standard spans. Place supports at the start and end of bends, and in the middle of large-radius bends. Joining Sections: Use couplers or splice kits to connect straight sections.

For optimal performance, place couplers at 1/5th of the span length; avoid placing supports directly under couplers. Creating Bends and Branches: Mesh trays can be cut, bent, or shaped on-site to form 90° bends, T-junctions, or reducers without pre-manufactured parts. Use the tray's flexible mesh structure to create custom angles and branches.

Securing Accessories: Fasten bends, couplers, and supports using the manufacturer's recommended hardware. Ensure all connections are tight and level to prevent deflection or cable strain.

Cable Installation

Lay cables gently into the tray, avoiding sharp bends or excessive pulling. Maintain the minimum bend radius for each cable type and ensure proper spacing to prevent overheating or mechanical stress. For heavy or bundled cables, verify that the tray's safe working load is not exceeded.

Safety and Maintenance

Always follow manufacturer instructions and local electrical codes. Inspect trays and accessories periodically for corrosion, loose connections, or deformation. Avoid using trays or accessories for unintended purposes, as this may void warranties and compromise safety.

By following these steps, mesh cable tray accessories can be effectively used to create a secure, flexible, and durable cable management system, reducing material waste and installation time while ensuring compliance with safety standards.
