Pre-galvanized Trough Cable Tray

Product Introduction

The main difference between tray type cable tray and trough type cable tray lies in their structure. The trough type cable tray is fully enclosed while the tray type cable tray has waist-shaped holes at the bottom. The trough type is not conducive to heat dissipation since there are no cooling holes, which can lead to a higher risk of overheating. On the other hand, the tray type cable tray has cooling holes at the bottom, making it better for heat dissipation.
The trough type cable tray is often used for laying sensitive cables like computer cables and communication cables, especially in heavily corrosive environments. It can shield interference of control cables and protect them from damage caused by harmful substances. The tray type cable tray, on the other hand, is widely used in different industries like petroleum, chemical, and electric power as it can handle both power cables and control cables.
The surface treatment options for tray type bridges include galvanizing, electrostatic plastic spraying, and hot galvanizing depending on the user's needs. It can also undergo special anti-corrosion treatment for extremely corrosive environments. In contrast, the trough type bridge is mainly suitable for laying wires and cables with small sections but a large number, while the tray type bridge is more suitable for power cables with large sections but a small number.
Overall, the application fields of tray type bridges are wider and more versatile than those of trough type bridges. However, both types have their distinct advantages and are useful in different scenarios, depending on the specific needs of the user.
