　　With the advancement of technology, in the 1970s and 1980s, some optoelectronic composite optical cables that were different from traditional optical cables and attached to power lines and power towers were developed. These optical cables are collectively referred to as power special optical cables

　　One of the differences between power system fiber optic communication and other fiber optic communication systems is the specificity of communication optical cables

　　The possibility of external damage to power special optical cables is small, and their reliability is high. Although their cost is relatively high, the construction cost is relatively low

　　After years of development, the manufacturing and engineering design of special power optical cables have matured, especially the all dielectric self-supporting optical cable (ADSS optical cable), which has begun to be widely used in the domestic power industry. The application of ADSS optical cable relies on the inherent line network resources of the power system, avoiding conflicts and entanglements with the outside world in frequency resources, routing coordination, electromagnetic compatibility, etc., and has great initiative and flexibility

　　When the optical cable is subjected to stable lateral wind with a wind speed of 0.5-4 m/s, a wind "vortex" will appear, forming a regular up and down wave like reciprocating motion. It belongs to the vibration prone area in open areas

　　The greater the static pressure on the optical cable and the higher the suspension point, the more likely it is to cause vibration, which can cause continuous friction between the quartz sand at the suspension point, especially the tension point, and the surface of the optical cable. This can lead to damage to the surface of the optical cable and the detachment of the quartz sand from the metal pre twisted wire, resulting in a decrease in the grip strength of the fittings

　　Therefore, attention should be paid to whether the anti vibration device is intact for optical cables with large spans and high hanging points, in order to prevent the phenomenon of optical cable dancing

　　In addition, when patrolling the line, attention should be paid to the ability of the ADSS optical cable outer sheath to withstand harsh weather conditions such as high temperature, strong winds, rain, and ice, and to prevent accidental cracking and aging of the sheath

　　Objectively speaking, communication in the power system belongs to an incidental weak current technology

　　The job advantages of a single communication industry are unmatched and incomparable for communication technicians in the power system - technicians generally feel that their status is subordinate

　　For this reason, frontline technical staff who have been engaged in the installation of power communication optical cables for many years need to have a comprehensive understanding and grasp of the technical content, especially the key technologies that may lead to faults and hidden dangers after the installation of communication optical cables, such as fragile fiber texture, low mechanical strength, high requirements for cutting and splicing technology, and complicated branching and coupling. Only by mastering and understanding them in advance can they scientifically grasp the workflow, operation links, and key technologies in the construction of outdoor communication optical cable racks and splicing in poor environments and complex situations, and then standardize work, implement details, and eliminate hidden dangers
