What is the appropriate length for electrical cable trays

The standard tray length is 3m. 6m can be produced upon request. Cable tray supports and protects power cables, communication cables and wires, and helps to expand, make stable and restructure the cable network. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. A tray that is too small will overheat and physically damage, and too large tray will drain the project budget. The available sizes for this model are: Height (H): 25 mm, 50 mm, 100 mm, 150 mm, 200 mm Width (W): Ranging from 50 mm to 1000 mm, depending on the height. 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. The standard tray length is 3m.
