How to fasten cable tray clips

Cable tray fixing clips are installed to securely anchor trays to structural supports, ensuring proper load distribution and compliance with electrical installation standards.

Preparation and Inspection

Before installation, all cable trays and accessories should be inspected for damage, handled carefully, and stored according to project material control procedures. Ensure that the trays are made of the appropriate material, such as hot-dip galvanized steel, aluminum, or stainless steel, depending on environmental conditions and project specifications (Paktechpoint).

Selecting Fixing Clips

Choose clips compatible with the tray type (ladder, perforated, or solid-bottom) and the support structure. Clips may include perforated clamps, beam clips, or specialized cable tray clips. For light loads, nylon cable ties or preassembled clamps can be used, while heavier trays require metal anchors or direct-fixing elements (Indexfix).

Installation Procedure

Position the Tray: Place the cable tray on the intended support, ensuring it is level and aligned with the cable routing plan. Horizontal trays should be laid flat, while vertical or edgewise trays require individual cable fastening every meter (Paktechpoint). Attach Fixing Clips: Secure the tray to the support using the selected clips.

Clips can be fastened to steel beams, welded steel structures, or concrete using self-drilling dowels or approved anchors. Ensure the clip spacing does not exceed 3 meters for ladder trays and 2 meters for perforated trays to prevent sagging or strain (Paktechpoint). Secure Cables: Once the tray is fixed, cables can be fastened using stainless steel strips, nylon ties, or perforated straps.

Horizontal trays typically require fastening every 2–3 meters, while vertical trays need more frequent attachment (Paktechpoint). Check Load Capacity: Ensure the tray and clips can support the intended load, typically designed for 100 kg/m for standard installations (Paktechpoint).

Tips and Best Practices

Use clips and fasteners that are tested and approved as a system to ensure safety and durability (BEAMA). Avoid using cable trays as walkways or ladders to prevent damage and personal injury (BEAMA). For quick installation, some modern clips, such as LINIAN cable tray clips, can be installed without tensioning tools, simplifying the process (YouTube).

Maintain proper spacing and alignment to allow for thermal expansion and easy cable maintenance. By following these steps and using the correct fixing clips, cable trays can be securely installed, providing a safe and organized pathway for electrical and instrumentation cables.
