Short answer: cable tray size should be selected by cable quantity, cable outer diameter, fill ratio, load span, tray type, material and installation environment.
| 50×50 to 100×100 | Common for light control cable and small power cable routing. |
|---|---|
| 150×100 to 300×150 | Used for medium cable bundles in industrial and building installations. |
| 400×100 and above | Used for larger cable routes where load, span and ventilation must be checked. |
| Tray type | Confirm perforated tray, ladder tray, trunking or trough tray according to cable heat and support requirement. |
Cable tray cannot be selected by width alone. Load span, material and accessories affect the complete system.
