How to wrap cables in cable tray covers

Wrap cable tray covers by fully encapsulating the cables with fire-resistant blankets, overlapping edges, and securing with stainless steel bands at regular intervals.Step-by-Step Instructions1. Prepare the Cable Tray and Wrap Material Ensure the cable tray is clear of debris and the cables are neatly arranged. Use a fire-resistant wrap such as FireMaster Cable Tray Wrap, which comes with a durable glass fiber reinforced aluminum foil for easy handling and installation . 2. Position the Wrap Place the blanket over the cable tray so that it fully covers the cables. Maintain a minimum of 75mm (3 inches) overlap between adjacent blankets to prevent gaps that could compromise protection . 3. Secure Joints and Cut Edges Any joints, overlaps, or cut edges must be tightly packed or sealed. For faced or fully encapsulated blankets, seal cut edges with a 100mm (4-inch) adhesive or tape to ensure complete coverage . 4. Attach the Wrap to the Tray Use stainless steel bands (minimum 12.5mm wide by 0.4mm thick) to secure the wrap. Place bands centered on overlaps and at minimum 262mm (10-1/2 inches) intervals along the span between overlaps. Additional bands should be added at elbows, 90-degree bends, or other critical points to maintain tight joints . 5. Check for Sagging or Gaps Ensure the wrap does not sag into the cable tray, which could create gaps. Adjust and tighten bands as needed to maintain a snug fit . 6. Final Inspection Verify that all overlaps, joints, and bends are properly secured and that the wrap fully encapsulates the cables. This ensures fire protection and maintains cable integrity during extended exposure .Tips for Best ResultsUse Velcro straps or cable ties to organize cables before wrapping, especially for large bundles, to prevent tangling and make installation easier .For long or heavy cable trays, consider wrapping in sections to maintain control and alignment.Always follow manufacturer guidelines for fire rating and installation standards to ensure compliance with safety regulations. By following these steps, your cable tray covers will be properly wrapped, providing both fire protection and organized cable management.
