[0002] High-voltage power lines are an indispensable part of modern power systems. They are used to transmit large amounts of electricity and connect various power stations, substations, and end users. These lines usually carry high-voltage electrical energy to reduce transmission losses and meet long-distance power transmission needs. Transmission towers are structures that support transmission lines. They are usually made of metal or concrete to ensure the stability and safety of the lines. Wires are conductors responsible for transmitting electrical energy. They are usually made of materials such as aluminum alloys or copper. Lightning arresters are devices used to protect lines from lightning strikes or overvoltages to ensure safe operation of lines in bad weather. Insulators are used to support wires and prevent contact with transmission towers. They are usually made of glass fiber or ceramics. Due to weather factors, such as ice on the surface of the line, strong wind vibration, etc., high-voltage power lines may cause the line to bear weight beyond the limit and break.
