[0002] Cable laying refers to the process of laying and installing cables along the surveyed roads to form cable lines. In power engineering, in order to meet the needs of power transmission, it is often necessary to lay cables across natural obstacles such as hillsides. According to the use environment, cable laying can be divided into multiple laying methods such as overhead, underground, underwater, wall and tunnel. Reasonable cable laying route is a very important process in cable laying.
