When the cable bridge is installed horizontally, if you go to the corner of the wall

When the cable bridge is installed horizontally, if you go to the corner of the wall, according to the Radian of the corner of the wall, you need to bend the cable through a horizontal bend of 45 degrees or 90 degrees. The traditional cable bridge is directly made of cold-rolled plate or hot-rolled plate, which is easy to rust and corrosion over a long time, which will eventually lead to the cable directly exposed in the external environment, affecting the normal transmission of cable signals.
Therefore, it is necessary to carry out anti-corrosion treatment, and now the commonly used anti-corrosion technology is galvanizing. Zinc is more active in the air and can react quickly with the air to form a layer of carbon metal oxide film, which can protect the internal zinc layer from external erosion. it can also protect the bridge plate from external corrosion, and now there are bridge manufacturers specializing in galvanizing iron parts such as bridges.
The following Beijing Beijing Weiye cable editor will introduce to you the relevant contents of the galvanized coating thickness standard.
The thickness of galvanized layer of cable tray depends on what kind of galvanizing process is used.
According to the standard of galvanized protective layer bridge, if the bridge adopts galvanizing process, the thickness of galvanized layer must be greater than or equal to 12um, and if the bridge adopts hot-dip galvanizing process, the thickness of galvanized layer must be greater than or equal to 65um.
The common thickness of zinc coating ranges from 5 microns to 100 microns. The conversion formula between galvanized layer thickness and galvanized layer weight is: galvanized layer thickness = galvanized layer weight / 7.14.
If the weight of the galvanized layer is 35.6 grams per square meter, the thickness of the galvanized layer is 5 microns per square meter, and if the weight of the galvanized layer is 100 grams per square meter, the thickness of the galvanized coating is about 14 microns per square meter.
