Fire protection standards for cable trays
Following standards such as IS, IEC, NEC, and NFPA ensures that cable tray systems meet approved safety requirements for commercial and industrial applications. Routine inspection and maintenance are critical for preventing electrical fires in cable tray systems. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with. Overloaded cables, poor ventilation, and damaged insulation can lead to overheating and fire. His research interests include power and new energy fire protection, smart safety and personnel protection, urban public safety and emergency management, disaster prevention and safety technology for long and large tunnels, and fire resistance of major engineering structures.
