Effective heat dissipation in cable trays requires exposing as much of the cable surface area to surrounding cooler air as possible. When trays lack proper ventilation or are overfilled beyond their rated capacity, the trapped thermal energy degrades the cable's protective. That's why good cable tray ventilation and heat dissipation design is so important. I'm going to explain how we make sure cables stay cool, looking at the main ideas, methods, and real-world uses. A cable tray is a bracket that supports and places cables.
