Description

Technical Field

[0001] The utility model relates to the technical field of high-speed rail construction, in particular to a high-speed rail electrification arm with conductive fluorocarbon paint. Background Art

[0002] The electrification arm is an important component of the high-speed railway system, and its functions and roles cannot be ignored. The setting of the arm helps to fix the position of the contact wire, ensuring that the train can normally contact the wire and the power supply is stable. At the same time, under the influence of wind or other external forces, the arm can effectively stabilize the position of the wire, ensuring that the train can run normally, and improving the stability and safety of the contact network. In addition, the setting of the arm also helps to guide the normal flow of current, ensuring that the train can be powered normally and avoiding power failures. However, in harsh natural environments, its electrical conductivity and corrosion resistance are often difficult to meet the needs of long-term stable operation. Therefore, how to improve weather resistance and corrosion resistance is an issue that urgently needs to be solved in the field of high-speed rail electrification systems. Utility Model Content
