What are the differences between cable ladder and perforated cable tray

In large projects, cable tray ladder is often used for stringing, which many people do not understand. What are the differences between cable ladder and perforated cable tray? Let’s have a brief understanding

1. Different specifications: Cable ladder trays are generally used for large ones and perforated cable trays are generally used for small ones

2. Different filling rates: The cable filling rate of cable rack ladder shall be higher than that of perforated cable channel of the same specification. However, the ladder type cable tray shall be controlled below 40%, and the filling rate of solt cable tray shall be controlled below 20%

3. The sealing is different: the cable ladder is semi open, and the wires or cables are directly exposed to the air, so the sealing is poor, while the sealing of the ventilation cable tray is good, especially the metal solid cable tray

4. Different purposes: cable ladder trays are mostly used to erect cables or wires with large specifications, which are suitable for use in strong current systems, while perforated type cable tray is generally only used to lay weak wires or wires with small specifications.

5. The spacing between supports and hangers is different: generally, for cable mesh tray and cable ladder of the same specification, when installing hangers, the spacing between hangers of cable ladders should be greater than that of perforated cable trays. When installing supports and hangers on cable ladders, the spacing should be controlled between 1.5 and 3 meters, while the spacing between mesh cable tray supports is generally not more than 2 meters

Edit summary: This is the end of the difference between cable ladder and perforated cable tray. Hope it will be helpful to you. Because there is no support point for indoor stringing, the cable ladder or perforated cable tray will be used for stringing. Note that the two are different and must be distinguished.
