[0002] Cable laying refers to the process of laying or installing cables along a surveyed route to form a cable line. According to the application scenario, it can be divided into several laying methods, such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying methods is very important to ensure the transmission quality, reliability and construction and maintenance of the line. According to the needs of cable laying and the laying method, cable clamps need to be used at a certain distance for fixing or laying the cables.
