Abstract

An arm structure of an extra high voltage transmission pylon prevents forward and backward movement of a connection rod due to a transmission line by absorbing the impact through a spring. A supporting frame(10) is comprised of the square pipe shape and is fixed at an upper lateral side of a pylon. A supporting shaft(20) is coupled with the supporting frame upward and downward. A bracket(30) is rotatably coupled with the support shaft and includes a coupling hole in the front surface. A rear end of a connection rod(40) is inserted into a coupling hole of the bracket. A suspension insulator connected to the transmission line is supported and coupled with the tip of the connection rod. Forward and backward movements of the connection rod are restricted by first and second hitching parts equipped in the connection rod. The forward and backward movements of the connection rod by the transmission line are prevented by absorbing the impact through a spring(37).
