1. Applicable fields
The slotted cable tray is a fully enclosed type of cable tray. This type of cable tray is more suitable for laying control cables for high-sensitivity systems such as computer cables, letter cables and thermocouple cables.
The tray-type cable tray is a kind of cable tray widely used in petrochemical industry, 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, from this aspect, the applicable field of the tray-type cable is wider than that of the slot-type cable, and the slot-type cable is mainly suitable for laying wires and cables with a small cross-section but a large number of them, while the tray-type cable tray It is mainly used for laying power cables with a large cross-section but a relatively small number.
2. Feature comparison
The trough cable tray has a very good effect on the shielding interference of control cables, and it also plays a very good protective effect on cables in very corrosive environments.
The tray-type cable tray is lighter in weight, can withstand a relatively large load, and its shape is more beautiful than that of the trough-type cable tray. In addition, the structure of the tray-type bridge is relatively simple, and it is also very convenient and quick to install. However, the surface treatment of the tray-type cable tray is divided into two treatment methods: crossing and painting, so in some relatively corrosive environments, special anti-corrosion treatment is required.
3. Heat dissipation
The trough bridge is a closed type, it has no holes, so in terms of heat dissipation, the heat dissipation performance of the trough bridge is much worse. The tray-type bridge has many waist-shaped holes at the bottom of the groove, so that its heat dissipation performance is much better.
