High altitude transmission line safety prevents bumping damping device

The utility model belongs to the technical field of transmission line safety protection. A high altitude transmission line safety prevents bumping damping device, is including setting up at damping frame, the fixed fastener body that sets up on each power transmission line at power transmission line middle part and set up the damping device between damping frame and fastener body, damping device including set up respectively on fastener body and damping frame and each other two guide sleeve that establish of slip cap, set up relative setting and polarity identical's two magnet and the spring of setting between two sleeves in two guide sleeve. The utility model discloses with lower transmission line the problem of collision takes place to sway by a wide margin to the upper -level winds masterpiece, through setting up damping device, can effectual buffering each other sway the collision motion, the damped motion reduction vibration frequency through each other reaches the steady purpose of quick recovering.
