Today, Jinan Cable Bridge Frame's small edition summarizes the basic steps of horizontal installation of grid bridge:
1. The grid bridge and its bracket and the metal cable conduit introduced or drawn must be grounded or connected to zero reliably. The full length of the bridge and its bracket should not be less than two places connected to the grounded or zero-connected trunk lines.
2. The two ends of the connecting plate between the non galvanized grid bridges are connected with copper core grounding wire, and the allowable load area of the grounding wire is not less than 4mm;
3. When the design is not required, the spacing of the brackets installed horizontally is 1.5-3 m, and that of the brackets installed vertically is not more than 2 m. For example, the expansion screw is used to fix the threaded steel from the ceiling construction to the corner bracket from the wall construction.
4. The two ends of the connecting plate between galvanized bridges do not cross the ground wire, but there are not less than two connecting bolts with anti-loosening nuts or anti-loosening washers at both ends of the connecting plate.
