随着社会经济的飞速发展和现代化建设进程的持续推进，整个社会对电力资源的

With the rapid socio-economic development and continue to promote the modernization process of the whole society demand for power resources is increasing, and all aspects of social dependence on power resources is gradually increased, so that the security of the operation of transmission lines and persistent put forward higher requirements. Effectively enhance the whole life cycle of the transmission line system can greatly contribute to the overall sustainability transmission line system, based on this paper the author analyzes the factors affecting transmission line project component service life, summed up the sort key impact of each component durability factors and failure mode, component performance combined power transmission lines, etching techniques and analysis of materials resistant protection technology, research from the design point made specific optimization measures designed to extend the life of the power transmission line

With the rapid development of social economy and the continuous progress of modernization, the demand for power resources in the whole society is increasing, and the dependence of all aspects of society on power resources is gradually increasing, thus putting forward higher requirements for the safety and durability of transmission line operation. The effective improvement of the whole life cycle of transmission line system can greatly promote the sustainable development of transmission line system as a whole, based on this, the author analyzes the factors affecting the service life of transmission line engineering components, combs and summarizes the key factors and failure modes that affect the durability of each component, combined with the performance of transmission line engineering components, The analysis of material corrosion resistance technology and protection technology, and the specific optimization measures to extend the design life of transmission line from the design point of view are put forward.

With the rapid development of social economy and the continuous progress of modernization construction, the demand of the whole society for power resources is increasing day by day, and the dependence of all aspects of the society on power resources is also gradually increasing, which puts forward higher requirements for the safety and durability of transmission line operation. The effective promotion of the whole life cycle of transmission line system can greatly promote the sustainable development of the whole transmission line system. Based on this, the author analyzes the factors that affect the service life of transmission line engineering components, summarizes the key factors and failure modes that affect the durability of each component, and combines the performance of transmission line engineering components, material corrosion-resistant technology and protection Based on the analysis of technology, this paper puts forward the specific optimization measures for prolonging the design service life of transmission lines from the design point of view
