Home / Fireproof separation spacing for cable trays
The gap area between firestop packs and cables should not exceed 1 cm2, and the packing thickness should be not less than 24 cm. This document outlines the key requirements for cable tray layout, installation, and fireproofing in industrial and commercial environments. Route Planning and Layout Principles Coordinate with Building Structure: Cable tray routing should align with architectural design, avoiding unnecessary. * Two (2) sticks of moldable putty (part number FSP-MPS) are also needed for each opening.
