Cable path section setting method

Disclosed is a cable path section setting method. The method comprises the steps that 1: (1), defining is conducted on cable trays and tag numbers of coding sections; (2), the sections are arranged onthe cable trays; 2, the tag numbers of the cable trays are replaced by the tag numbers of the sections; 3, the path information of the sections of all cables is aggregated; 4, the cable information included in each section is screened; 5, the cable loading capacity and margin of each section are checked; 6, the using amount of the cable is determined; 7, the process data of step 1-6 is organized,and the sections are compiled to finish the setting of a cable path section. According to the method, the problems that local cable loading capacity of the tray cannot be accurately presented and thedesign flow of the cables cannot be accurately measured due to inaccurate cable path information are solved, and the construction efficiency is improved. 种电缆路径截面的设置方法，采用以下步骤：：⑴对电缆托架进行定义和编码截面的位号；⑵在电缆托架上布置截面；二：用截面的位号代替电缆托架的位号；三：
