[0002] High - voltage power transmission generally adopts the overhead line method carried by iron towers. Using high - voltage and extra - high - voltage overhead power lines is the main way for long - distance power transmission and distribution. The power lines and tower accessories are long - term exposed in the wild and are prone to damage such as strand breaks, wear, and corrosion due to continuous mechanical tension, electrical flashover, and material aging. If not repaired and replaced in time, originally minor damages and defects may expand, ultimately leading to serious accidents, causing large - area power outages and huge economic losses. Therefore, it is necessary to regularly inspect high - voltage lines.
