Fire resistance limit of fireproof cable trays
Fire rating defines how long a cable tray system can maintain its structural integrity during a fire. Common fire resistance periods include 60, 90, and 120 minutes, depending on project requirements. Materials like steel. The gap area between firestop packs and cables should not exceed 1 cm2, and the packing thickness should be not less than 24 cm. Cover plates should be square, of consistent suitable. For fire-resistant cable trays, load capacity must be considered in two conditions: Normal operating conditions Fire exposure conditions, when steel strength is reduced by heat A tray that performs well at room temperature may deform or collapse quickly during a fire if it is not designed for. The fire-resistant cable tray and conduit assemblies play a critical role in maintaining safe and compliant industrial operations, particularly within hazardous locations such as chemical plants, oil refineries, and manufacturing facilities. They primarily utilize the heat insulation and flame-retardant properties of the fire-resistant boards to protect cables from fire.
