Description of fire-resistant characteristics of fire-resistant cable tray
Fire-resistant cable trays are suitable for laying power cables up to 10 kV, as well as control cables, lighting wiring, and other overhead cables in indoor and outdoor cable trenches and tunnels. However, many people may not be familiar with their fire-resistant properties. The steel skeleton is primarily machined from high-quality cold-rolled steel, resulting in a high load-bearing capacity and a long service life. The cross-section of the steel skeleton is neat and free of burrs and sharp corners, and the grooves are smooth and flat without sharp protrusions. After processing, the cross-section is uniform, free of defects such as bends, twists, cracks, and edges.
