They provide robust support and are particularly suited for heavier cable loads or cables requiring extensive ventilation. Cable trays are ideal where cables need moderate protection and ventilation while. Cable ladders, cable trays and their supports should be strong enough to meet the load requirements of the cable management system including cables and any future cable additions and any other additional loads applied to the system. They are not intended to be used as ladders, walk ways or support for people as this can cause personal injury and also damage the system and any. Cable trays and cable ladders are indispensable components in modern electrical wiring systems, providing organized support and protection for cables and wires. These systems play a crucial role in ensuring the safety, efficiency, and longevity of electrical installations across various industries. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Not all cable trays are equivalent.
