The installation process for FRP (Fiber Reinforced Plastic) cable trays is simple and efficient. Follow these steps to ensure a proper installation:
1. Planning and Preparation
Site Inspection and Measurement: Perform a detailed inspection of the installation site. Identify the cable tray route, obstacles (such as pipes, ventilation ducts), and turning points.
Tray Length and Type: Accurately measure the route and determine the length of the FRP cable tray and the number of supporting fittings (such as elbows, tees, crosses, reducers) you will need.
Load Calculation: Estimate the total weight of the cables. Check the tray type (ladder, solid bottom, or perforated) and its load-bearing capacity to ensure it can handle the expected weight.
Material Inspection: Before beginning installation, check the quality and quantity of all FRP tray sections, joints, hangers, brackets, and fasteners (nuts and bolts).
2. Preparing the Support Structure
Support Spacing: Support structures for FRP trays are typically spaced between 1.5 meters and 3 meters apart, depending on the load and manufacturer's recommendations. Install additional supports near points where the tray will be subject to additional load (such as joints or bends).
Support Type: Supports used (such as wall brackets, ceiling hangers, or floor supports) should be securely anchored to the concrete or steel structure.
Support Strength: Ensure the supports can easily support the total weight of the tray and cables. Install all supports at the correct level and in a straight line.
3. Fitting the Tray onto the Supports
Fitting the Tray: Place the first section of the FRP tray onto the prepared support structure. Use FRP clamps or manufacturer-recommended stainless steel fasteners to secure the tray to the supports.
Assembly: Use splitter plates and FRP/stainless steel nuts and bolts to connect the next section of the tray to the first. Tighten all joints tightly and securely.
Cutting (if necessary): If the tray needs to be cut to length, use suitable tools (such as a fine-tooth saw or cut-off wheel) to cut the fiberglass. Smooth the edges after cutting.
4. Safety and Organization
Safety Equipment: The installation team must wear safety equipment such as helmets, safety glasses, gloves, and safety shoes.
Cable Laying: Lay the cables in the tray in such a way that they remain organized and do not exceed the maximum filling capacity of the tray. Use suitable cable ties or clamps to secure the cables tightly within the tray.
Grounding: Although the FRP tray itself is non-conductive, ensure proper earthing or grounding for other system components and cable sheaths, if necessary, in accordance with electrical safety standards.
5. Final Inspection
After installation is complete, inspect all tray sections and joints to ensure they are sound, level, and securely installed.
There should be no sharp edges or loose fasteners that could damage cables.
With proper installation, FRP cable trays provide a long-term, corrosion-free, and low-maintenance cable management solution.
