An arm for maintaining the stable fixing of an extra high voltage transmission and distribution lines prevents damage by buffering, absorbing, and attenuating vertical and horizontal vibration and impact applied to an electric wire by a tension control device including a hydraulic cylinder. If the electric wire is shaken due to the change of weather like wind, the function loss due to a damaged insulator or the separation of the insulator from the arm is minimized by buffering and absorbing the vibration and impact of the electric wire generated in back-and-forth, right-and-left, and up-and-down directions by the tension control device. |
