With the increase of the electric load, the wire diameter of the wire designed for the medium-voltage line is thicker and thicker, the wire can vibrate along with the wind, and the binding wire is subjected to up-and-down tension caused by relief in the running process, front-and-back tension caused by large span and the like. The insulator is easy to cause the cable binding flying-off fault in the weather of strong wind, ice coating and the like. The wire binding flying off can also cause the interphase short circuit of the bare conductor, the broken wire caused by the discharge of the bare conductor to the cross arm, and even has huge potential safety hazard due to insufficient distance to the ground. Therefore, the overhead line column type insulator binding hardware is very necessary to design, the binding hardware is used in a large-span area, a large wind power area and a repeated ice area, fault power failure caused by the fact that the insulator binding wire is broken off can be avoided, power supply reliability is improved, and the potential public safety hazard caused by the fact that the conductor is short of the ground safety distance caused by the fact that the binding wire is broken off can be avoided.
