Mechanical design of the cable, determination of the suspension point and selection and installation of the matching hardware. The mechanical properties of ADSS cable mechanical performance cable are mainly reflected in the maximum operating tension, average running tension and ultimate tensile strength of the cable. The national standard for ordinary optical cables specifies the mechanical strength that optical cables with different modes of use (such as overhead, pipelines, direct burial, etc.) should have. The ADSS cable is a self-supporting overhead cable, so it must withstand the long-term effects of its own gravity and must withstand the baptism of the natural environment. If the mechanical performance of the ADSS cable is not designed properly and is not compatible with the local weather, the cable will have potential safety hazards and the life expectancy will be compromised. Therefore, each ADSS cable project must be designed with professional software according to the natural environment and span of the cable routing to ensure that the cable has sufficient mechanical strength. The OPGW directly uses the optical fiber in the transmission ground. The ADSS is a self-supporting optical cable, and the optical cable is directly hung on the transmission line. These two optical cables have been widely used in domestic power systems, and both types of optical cables are also used. There are special technical regulations. All-media self-supporting optical cable (ADSS): All-medium optical cable has excellent characteristics for preventing electromagnetic influence and lightning protection, and is light in weight, small in outer diameter, and easy to use in overhead. It has been widely used in power communication networks. . ADSS is also a good choice of fiber optic cable types in the telecommunications sector in the environment of anti-electromagnetic interference and thunderstorms.
