  • What causes cable trays to shrink due to cold

    What causes cable trays to shrink due to cold

    The cable trays made of metal, in fact, expand and contract depending on the temperature. The metal shrinks and shortens when it becomes cold. In case there is no space to move it, the tray could become deformed or break the bolts that attach. Extreme cold weather can cause cables to stiffen, crack, and even break. These failures, whether isolated or interconnected, significantly impact the performance and safety of the cable tray system. A good understanding of how materials perform at extreme temperatures is critical to avoid serious injuries and expensive down-time.
