The requirement for models and airborne equipment of helicopter patrol that operate on overhead transmission lines in high altitude areas is quite different from the equipment used in ordinary area. Especially in Yunnan with its complex terrain, the selection of helicopter patrol equipment is particularly crucial considering large difference in relative altitude. Based on the characteristics of Yunnan Power Grid, this paper focuses on the selection of models and airborne equipment of helicopter patrol used in the overhead transmission line operating at altitudes of 2500 meters and above. The suitable equipment for overhead line patrol at high altitude is determined to ensure the safety and quality of operations.
