Today, Jinan Cable Bridge Frame's small edition summarizes the basic steps of horizontal installation of grid bridge:

1、网格桥架及其支架和引入或引出的金属电缆导管必须接地或接零可靠，全长及其支架应不少于2处与接地或接零干线相连接;

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、非镀锌网格桥架间连接板的两端跨接铜芯接地线，接地线允许载面积不小于4mm;

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、当设计无要求时，桥架水平安装的支架间距为1.5~3m;垂直安装的支架间距不大于2m。如是从吊顶施工就用膨胀螺丝固定螺纹钢固定~从墙壁施工要用山角架固定;

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、镀锌桥架间连接板的两端不跨接接地线，但连接板两端不少于2个有防松动螺帽或防松动垫圈的连接固定螺栓。

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.
