The steel trough type cable tray is fully sealed and has strong anti-interference ability. It uses high-quality cold galvanized steel plates, also known as "electro galvanized cable tray". It is used in basements and strong and weak motor rooms. Because it belongs to the drying room, the only disadvantage is that the corrosion resistance is relatively poor, and the service life of the cable tray is not as long as that of other materials. It can only be installed in the drying room and places without corrosion protection requirements, and the price is cheaper than that of other materials, This is also an advantage.
Trough type cable tray can be used for fully enclosed cable laying, suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has a good effect on shielding interference of control cables and cable protection in heavily corrosive environment. For a long time, the traditional bridge has been used in China to route various power cables or control cables, while in Europe and the United States, Grid bridge is widely used. So what are the advantages of this trough type bridge over the traditional closed bridge?
First of all, the trough type cable tray allows all cables to be visible, which can comprehensively control the quality of wiring engineering. In case of failure in the future, it can also quickly identify the problem cables and take corresponding measures. Moreover, due to the natural ventilation and heat dissipation of cables, the heat will not gather, so cables with smaller cross-sectional area can be used, so as to reduce the cable procurement cost.
Second, the trough type cable tray allows the outgoing line from any point, which can be easily connected with various machines and equipment, and the outgoing line point can be changed at will; Moreover, it is light and flexible, and can be installed on the top, bottom and periphery of the production equipment. It can easily swim among various instruments and be installed along the production line and assembly line.
