Fire prevention between layers of vertical cable trays

Stopping the fire inside the tray is the most effective way to prevent broader system impacts. Direct Low Pressure (DLP) clean agent systems offer a practical solution for detecting and suppressing fires inside cable trays. 7 products are successfully used to protect cables in high-rise buildings, industrial buildings, and offshore facilities as well as in sensitive areas, such as hospitals, airports, production. The current version of ISO 14520-1 (Gaseous Fire-Extinguishing Systems, Physical Properties and System Design, Part 1: General Requirements) requires only wood crib fire extinguishment testing for the establishment of minimum Class A design concentrations. Safety of a cable tray is not a matter of compliance with codes, but a matter of saving human life and billions of dollars' worth of infrastructure. Poorly fitted trays may serve as a fuse in case of a short or a top chimney in case of a fire.

Cable tray (or cable ladder) systems are a popular alternative to electrical conduit systems, as they have an outstanding record for dependable service, design flexibility and cost savings in commercial and industrial applications. of galvanized products is a linear function of the thick-ness of he zinc coating. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. A tray that is too small will overheat and physically damage, and too large tray will drain the project budget.
