Perforated Cable Tray A perforated cable tray is a type of cable management system used to support and organize electrical cables in various settings, such as commercial buildings, industrial facilities, and data centers. It consists of a series of interconnected metal trays with a perforated pattern. The primary purpose of a perforated cable tray is to provide a structured pathway for routing and supporting cables. The tray's perforations or holes allow for proper airflow and ventilation, which can help dissipate heat generated by the cables, particularly in high-density installations. Adequate ventilation is essential for maintaining optimal operating temperatures and preventing overheating, which can affect cable performance and lifespan.
