Description :

　　Principles for selecting cable hanging points

　　(1) The optical cable should be suspended in a location with a lower electric field strength, that is, an AT type sheath of 20KVm and an PE type sheath of 20KVm;

　　(2) The projection of optical cables in both horizontal and vertical directions should not intersect with wires and ground wires to avoid whip strikes during wind deflection and swinging;

　　(3) The optical cable should not cause friction or collision with the tower;

　　(4) Does the fiber optic cable need to be kept connected to residential areas, railways, and highways? The safe distance between communication lines and other power lines;

　　(5) The hardware for hanging optical cables must be installed on tower materials that can withstand lateral tension, so that the tower is subjected to less force;

　　Among them, the magnitude of the high-voltage induced electric field is generally calculated by ADSS fiber optic cable manufacturers based on the preliminary design of the power design institute, providing electric field strength and distribution maps for different tower models. Combined with the specific difficulty level of construction, the hanging point position of the fiber optic cable is finally determined.

　　In specialized application software, as long as the phase line coordinates of the tower are provided according to the established coordinate system? The diameter of the phase line, the type of ground wire, and the voltage level of the line can be used to obtain an induced electric field distribution map. Therefore, in the preliminary design preparation stage, the detailed and reliable information of the line is the guarantee of the overall project quality.
