With the rapid development of China's economy and society

the demand for electricity is growing explosively. As the "aorta" of power energy transmission

transmission lines bear the key mission of efficiently transporting electricity from the power generation terminal to thousands of households and various industries. Its safe and stable operation is of irreplaceable strategic significance for ensuring electricity supply for people's livelihood and promoting social and economic development. This article focuses on the hidden dangers of external damage of transmission lines

and deeply discusses the prevention and control technology and management measures. By analyzing the main types and hazards of the current external force damage of transmission lines

and studying advanced monitoring and early warning

protection and reinforcement and other prevention and control technologies

it aims to provide theoretical and practical reference for improving the safe operation level of transmission lines and reducing the risk of external force damage.
