In the fields of electric power, communication and other related fields, column insulators are widely used as key electric insulation devices for various overhead lines and equipment supporting structures. These insulators are critical to ensure proper operation of power and communication lines and to ensure public safety. However, as the service life of the equipment increases or the environmental factors influence, the post insulator may be degraded or damaged, and needs to be replaced in time to maintain the performance and safety.
Conventional post insulator replacement methods typically require an aerial operator to climb onto the pole, remove the old insulator, and place it on the ground using a rope or similar tool. Then, ground staff takes down old insulator to bind new insulator again, later aerial operation personnel again use rope to carry new insulator to required position and install. The traditional method is low in efficiency, and when the weight of the insulator is large or the number of insulators is large, the physical requirements of air operators are extremely high, and the operation difficulty and the potential safety hazard are increased.
