When working at high altitude on poles, the higher the voltage level, the greater the distance between the grounding point and the wire, the larger the angle of rotation of the line pole tower, the longer the grounding wire is required, and the less easy it is for personnel to hang up when working; sometimes when there is wind, The hang time required for the job is just longer. During the operation process, the labor intensity of the personnel on and off the pole is high, which may easily cause muscle fatigue and cause danger.
