Bridge structure type

Can be divided into perforated trays, non-porous trays, ladder frames and assembled trays.

(1) A perforated tray is a groove-shaped member composed of a bottom plate and a side plate with perforations, or a member formed by punching and bending a single steel plate.

(2) The non-porous tray is a grooved member composed of a bottom plate and side edges or made of a single steel plate.

(3) The ladder frame is a trapezoidal member composed of a side edge and a plurality of crosspieces.

(4) The assembled pallet is a component that is connected to the pallet by bolts or plugs that are suitable for any combination of the engineering sites. The bridges are used to lay cables. When the low-voltage cables and control cables share the same pallet or ladder frame, ladders or pallets with intermediate partitions should be used.

The difference between the trough bridge and the tray type bridge

1. Applicable fields

Slotted cable tray It is a fully enclosed cable tray. This type of cable tray is a control cable suitable for laying high-sensitivity systems such as computer cables, letter cables and thermocouple cables.

The tray cable tray is a cable tray widely used in petrochemicals, television and telecommunications, etc., and it is not only suitable for the installation of power type cables, but also for the laying of control cables. Therefore, in this respect, the tray type cable is suitable for the wider field than the slot cable, and the slot cable is mainly suitable for laying a small but large number of wires and cables, and the tray type cable tray Mainly used for laying power cables with large cross sections but relatively small numbers.

2, feature comparison

Trough cable tray This kind of bridge has a very good effect on the shielding interference of the control cable. In addition, it also has a very good protection effect for cables in very corrosive environments.

The tray type cable tray is lighter in weight, can withstand a large load, and its shape is more beautiful than that of the trough bridge. In addition, the tray type bridge has a relatively 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 treatment methods, namely, crossing and painting, so in some corrosive environments, special anti-corrosion treatment is required.

3, heat dissipation

The trough bridge is of a closed type and has no holes, so the heat dissipation performance of the trough type bridge is much worse in terms of heat dissipation. The bottom of the tray type tray has a lot of waist holes, so its heat dissipation performance is much better.
