Disadvantages of fire-resistant cable trays
If the path is blocked, the metal tray can cause a shock, which can pose a great danger to anyone in contact with it. Even though steel and aluminum are good electric conductors, the interconnection areas between trays are weak. Poorly fitted trays may serve as a fuse in case of a short or a top chimney in case of a fire. Such forces can cause the cable's outer insulation to break, or worse. Unlike low-rise structures, high-rise buildings face unique risks during a fire: Longer evacuation routes and stairwells High cable density across vertical shafts Dependence on mechanical systems for smoke control Greater reliance on emergency power and communication systems If cables fail early in.
