Explanation of the heat island effect in cable trays

Poor Heat Escape: Cable trays often have limited space, and many cables are packed in tightly. If this is not detected early it can cause significant loss of plant, down time of production, and in severe situations even risk to life. But with more and more cables and longer use, cables getting too hot is a big issue. That's why good cable tray ventilation and heat. How to Avoid Severe Heating of Metal Cable Trays The eddy currents from AC power cables induced in the metallic tray generate additional heat. Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to. ProReact Linear Heat Detection (LHD) offers a proven solution. Engineered for continuous monitoring and early warning, our cable-based detection system is ideal for protecting cable trays—whether single-tier, multi-tier, or densely packed.
