Key Considerations for Using ADSS Optical Cables: Zhongtian Cable Manufacturer Clarifies Your Doubts

2022-04-24


        Zhongtian Optical Cable Manufacturers regard a robust communication network as the fundamental prerequisite for the reliable operation of power systems. Such a network enables the rapid transmission and sharing of diverse data and information, thereby providing dependable support for grid inspection and maintenance. In the construction of communication networks, the use of ADSS optical cables is steadily increasing, as they can enhance communication quality and meet the varied needs of power-sector personnel. However, due to external factors, numerous issues may arise in the application of ADSS optical cables, which can impede the long-term development of power enterprises. Therefore, it is essential to strengthen rigorous control over all stages of deployment to fully leverage the performance advantages of ADSS optical cables.

As electricity consumption continues to rise, the performance requirements for power communication networks are becoming increasingly stringent. Only by ensuring robust communication conditions can the safety and stability of the power system be enhanced, thereby delivering improved power supply services to customers. The practical application of ADSS optical cable communication effectively expands transmission capacity and ensures efficient signal transmission. It is a key enabler for the sustainable development of China’s power industry and aligns with the current needs of smart grid construction.


The performance of ADSS optical cables is subject to external environmental conditions, human factors, and cable-specific characteristics, which can give rise to a variety of issues. In severe cases, these problems may lead to transmission-line failures or even serious power-safety incidents, thereby hindering the continued advancement of power-sector operations. Therefore, it is essential to strengthen the effective management and maintenance of ADSS optical cables to mitigate operational risks. To this end, application-specific solutions should be developed in accordance with the operational characteristics and requirements of the communication network, so as to prevent the occurrence of unexpected problems.


  When installing ADSS optical cables, manufacturers such as Zhongtian Optical Cable emphasize the need to comprehensively consider various factors, including sag, span length, and external environmental conditions, while clearly defining the number of cables required and the appropriate installation method. It is also essential to test the mechanical strength of the ADSS cable to ensure its performance meets specifications. ADSS optical cables are widely used in overhead power transmission lines, meeting the requirements for pole-and-tower installations, offering excellent cost-effectiveness, and helping to reduce overall power infrastructure construction costs. Stranded ADSS cables are extensively applied, typically suitable for lines at or below 220 kV. Proper fixation of the load-bearing and suspension wires helps minimize adverse impacts on the cable.


   Zhongtian Optical Cable Manufacturers acknowledge that prolonged exposure to the external environment can lead to an increase in soluble salts on the surface of optical cables and that dust deposition can also have an adverse effect. When a semi-conductive contaminant layer forms, the surface resistance of the cable decreases. If significant induced voltages are present in the surrounding environment, leakage currents may be generated. The resulting dry-band arc discharge is the primary cause of electrical corrosion. Once electrical corrosion occurs, ADSS optical cables can be damaged, compromising communication performance and posing substantial safety risks. Furthermore, when using vibration-damping dampers, failure to maintain an adequate clearance from ADSS optical cables can trigger corona discharge, which in turn can lead to electrical corrosion.
