【Issues in the Application of ADSS Optical Cables】
(1) Electrical Corrosion
Long-term exposure to the external environment can lead to an increase in soluble salts on the surface of the optical cable, and it can also be affected by dust. When a semiconductor pollution layer appears, the surface resistance of the cable decreases. If there is a large induced potential in the surrounding area, it can trigger leakage current. Dry band arcing caused by this is the main cause of electrical corrosion. When electrical corrosion occurs, it can lead to damage to ADSS optical cables, affecting good communication effects, and posing significant safety hazards. When using vibration dampers, failure to control the distance from the ADSS optical cable can also cause electrical discharge situations, leading to the occurrence of electrical corrosion.
(2) Mechanical Performance Deterioration
The mechanical performance of the cable is influenced by its stress characteristics and operating conditions. Failure to make a reasonable choice of ADSS optical cables during selection is the main reason for problems in subsequent use. Failure to analyze and evaluate the stress data of the optical cable from a static mechanics perspective leads to uneven stress during use, resulting in serious damage during tension. Calculations on tension conditions and sagging using relevant professional software are necessary. However, external factors make the calculation process complex, making it difficult to obtain reliable data, thereby resulting in poor protection of the mechanical performance of ADSS optical cables.
(3) Dynamic Changes
Electrical conditions are not static but exhibit dynamic changes, which also have a significant negative impact on the application of ADSS optical cables. Usually, calculations are based on static changes, and the lack of analysis of the performance of optical cables under dynamic conditions can easily cause cable failures, which are detrimental to the operation of communication networks. In addition to clarifying the distance of ADSS optical cables, attention should also be paid to their hanging point conditions in analyzing the electromagnetic status. However, analysis work in practical settings often lacks dynamism, increasing the difficulty of computational processing.
(4) Environmental Factors
Environmental factors are the main factors affecting the performance of ADSS optical cable applications. Especially when there are large temperature differences in the external environment, it can also cause changes in the performance of ADSS optical cables. Simulation experiments are often needed to analyze the characteristics of their impact under different temperatures, to obtain changes in cable performance under different temperatures. The use of ADSS optical cables is also affected by strong winds. If the wind is strong or the wind speed is too fast, it will affect construction and application. In winter, there is often a lot of ice and snow coverage, increasing the load on the cable and posing significant safety hazards.
【Methods to Solve Issues in the Application of ADSS Optical Cables】
(1) Prevention of Electrical Corrosion
Reasonable selection of cable hanging points can reduce the probability of electrical corrosion, enhancing the quality of operation of the power communication network. Scientific planning of the line should be carried out to obtain and evaluate comprehensive information on the distribution characteristics and intensity of induced electric fields, to ensure the scientificity and feasibility of hanging point positions, and to reduce the impact on ADSS optical cables. The use of corona rings can control the occurrence of corona discharge effectively. The corona discharge voltage value is significantly increased, thus controlling the occurrence of corona discharge. In practical work, targeted analysis of electrical corrosion issues caused by different factors should be conducted to clarify specific impact characteristics, thereby taking effective preventive and control measures.
(2) Rational Selection of Cables
Reasonable selection of ADSS optical cables can also improve their operational reliability and reduce the failure rate of lines. Comprehensive consideration should be given to various influencing factors of ADSS optical cables, and advanced computer software should be used for simulation and calculation. Considering the influence of mechanical performance, dynamic factors, weather factors, etc., to ensure that practical and feasible plans can be formulated for on-site installation. Enhanced communication and communication with relevant manufacturers, comprehensive control of cable performance to prevent the occurrence of multiple problems in applications. The application of PE outer sheath material resistant to electric traces is more common in practice, which can effectively improve the resistance to electric traces of optical cables and prolong their service life.
(3) Strengthening Construction Control
During the construction process, the quality of cable installation should be controlled, the layout of the line should be clear, and the surrounding trees, buildings, and pipeline conditions should be surveyed in advance to reduce the impact of external factors on the operation of ADSS optical cables and prevent cable failures caused by construction environment issues. Cable protection should be done well during construction, especially timely cleaning of the surface to prevent flashover issues from causing serious faults. Comprehensive supervision should be strengthened at the construction site to ensure strict compliance with relevant technical standards and specifications during installation, to prevent faults caused by improper operation.
(4) Maintenance and Operation
A comprehensive maintenance plan should be formulated for ADSS optical cable operation, and hidden problems should be thoroughly investigated and controlled to prolong service life. Reasonable operation and maintenance plans should be formulated according to the actual operation requirements of power lines to ensure the performance and safety of cables meet the requirements. The maintenance process should be optimized reasonably, and a sound system should be established to prevent formal issues from occurring during maintenance operations. Inspection should be carried out using specialized maintenance tools, especially increasing maintenance efforts after severe weather to prevent serious damage caused by external environmental factors.
【Conclusion】
ADSS optical cables have significant advantages in performance, thus becoming a common type of optical cable in current power communication systems, ensuring good transmission quality. However, issues such as electrical corrosion, mechanical performance deterioration, dynamic changes, and environmental factors affecting ADSS optical cable applications have also led to a decrease in the stability and safety of communication networks. Therefore, through preventive measures such as preventing electrical corrosion, rational selection of cables, strengthening construction control, and good operation and maintenance, the application level of ADSS optical cables can be gradually improved, and their performance can be fully optimized.
