Are fire protection cable trays the same as power cable trays
Cable trays hold the wires for things like power and communication. They seem like separate things, but they need each other to keep buildings safe. We will look at how these two systems team up to make sure. Cable tray systems provide a safe, organized, and flexible method for supporting insulated conductors and cables in commercial and industrial electrical installations. However, they also pose a major fire risk—once a cable tray catches fire, it can spread rapidly across multiple zones. Steel is the most appropriate due to its ability to withstand melting when compared to aluminum in a way that it serves up to 90 minutes in wire protection. Through NEMA and the Cable Tray Institute numerous articles, standards, and other general guidance can be found regarding the proper use and installation of cable tray systems.
