For trough bridges and tray bridges, these two types of bridges are different in many respects. What differences do they have between these two bridges? Let's take a look at the introduction of the following small series. It.
Bridge type of structure
It can be divided into perforated trays, non-porous trays, ladder racks, and assembled trays.
(1) The perforated tray is a groove-shaped part consisting of a bottom plate and a side plate with an eyelet, or a part made by punching and bending a whole steel plate.
(2) The non-porous pallet is a trough type component made up of a bottom plate and a side or made of a single steel plate.
(3) The ladder frame is a trapezoidal component composed of a side edge and a plurality of crosspieces.
(4) Assembled trays are components that are connected to trays by means of bolts or plug-in connections suitable for any combination of holes in the project site. Bridges are used for laying cables. When low-voltage cables and control cables share the same tray or ladder, ladder frames or trays with intermediate partitions should be used.
Difference between trough bridge and tray bridge
1. Field of application
Trough cable bridge It is a fully enclosed type of cable bridge, this type of cable bridge is more suitable for the laying of computer cables, letter cables and thermocouple cables and other high sensitive system control cables.
The tray type cable tray is a kind of cable tray which is widely used in petrochemical industry, television telecommunication and so on, and it is not only suitable for the installation of power type cables, it is also suitable for the control cable laying. So in this respect, the tray type cable has a wider application area than the slot type cable, and the slot type cable is mainly applicable to the laying of a small but large number of wires and cables, and the tray type cable tray. It is mainly used for laying large but small number of power cables.
2. Comparison of features
Trough cable tray This kind of cable tray has very good effect on the shielding interference of the control cable. In addition, it also provides very good protection effect to the cables in the corrosive environment.
The tray-type cable tray has a lighter weight, a higher load capacity, and a better appearance than the trough. In addition, the tray bridge has a simple structure and is very convenient and quick to install. However, the treatment of the surface of the tray type cable tray is divided into two kinds of treatment methods, namely crossing and painting. Therefore, in the case of some corrosive environments, special anti-corrosion treatment is required.
3, heat dissipation
The trough bridge is of the closed type. It has no holes, so the heat dissipation performance of the trough bridge is much worse. The bottom of the tray-type bridge is a lot of waist-shaped holes, so its heat dissipation performance is much better.
