Where there are cables, there are bridges. The bridge has a wide range of applications, involving all walks of life, most of which are used in data centers, offices, Internet service providers, hospitals, schools/university airports and factories. How to protect the cable bridge in Shandong during installation?
1、 If the cable tray is installed, the facilities and steps to prevent the cable from being scratched must be available. For example, the arc shape of various tees, elbows and crosses that are easy to connect must be connected when the cable is led down.
The cable tray must be sealed when it is introduced from outdoor to indoor. For example, sand seal or fireproof blocking material can be selected. In addition, if glass fiber reinforced plastic is used for bridge facilities, it must be inclined when it is introduced from outdoor to indoor.
Generally, when the slope reaches 1%, it can prevent rainwater irrigation. However, different methods should be adopted according to different installation forms, and the available products must be carefully and comprehensively considered.
2、 If the support used is in the form of fluid, its pattern must be embedded in the iron parts for welding, and the good one is also in the form of shrinkage bolt flow. If there are cables in the center, its application limitations must be universal enough. Such installation methods will be set more or less in different industries. Most of them are used in central offices of various data and Internet service providers.
3、 As a cable bridge, there must be measures to prevent the cable from being scratched, so when we draw the bridge on the plan, we must determine the specific coordinates of its starting point, the midpoint of the turning point and the branch point, including various lifting points. In addition, the full length of the straight line must be indicated on the drawing, including various turning points, models and specifications, elevations, etc.
4、 If it is necessary to bind the cable at the wiring position, it is not allowed to place the cable cloth, and try not to cross and overflow the slot, so the cable should be bound and fixed at the entrance and exit of the cable or at the corner. If it is a vertical trunking cloth, it should be fixed with a cable support every one meter. Only in this way can we ensure that the specifications and requirements of the project are qualified.
There are indeed many things to pay attention to when laying the cable tray. In order to make it more functional and beautiful in appearance, we have to consider its symmetry of workmanship and distance separation at all times.
