Install fire barriers within the tray to isolate different fire zones. When cable trays pass through walls or floors, seal openings using fire-rated penetration sealing materials. Cable tray installation must comply with specific technical standards to ensure electrical safety, system reliability, and long-term maintainability. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. * Two (2) sticks of moldable putty (part number FSP-MPS) are also needed for each opening. Select tray materials and finishes that match the hazard: hot‑dip galvanised steel or stainless for durability; aluminium for lighter loads; FRP for corrosive plants. Therefore, it is crucial to set up fire-blocking sections (fire sections/fire partitions) on cable trays and select appropriate fire-blocking sections.
