Home / Ventilation engineering includes cable trays
These trays are used to support and protect the cables, but they must also allow air to circulate freely, ensuring that the heat generated by the cables does not build up and damage them by overheating. Skipping ventilation screening on cable tray installations leads to hidden thermal bottlenecks. I've seen a 600A feeder run in a solid-bottom tray derate so severely that the conductor temperature exceeded 90°C rating within two hours of full load — the engineer had assumed that because the tray. Cable tray (or cable ladder) systems are a popular alternative to electrical conduit systems, as they have an outstanding record for dependable service, design flexibility and cost savings in commercial and industrial applications. But with more and more cables and longer use, cables getting too hot is a big issue. A properly designed setup ensures continuous operations while protecting human lives and expensive infrastructure from devastating fires.
