A tension regulation apparatus for a power transmission tower is provided to prevent damage of a wire and check leakage of gas in a cylinder with the naked eye, thereby promptly maintaining and repairing the tension regulation apparatus. A tension regulation apparatus for a power transmission tower controls tension of a wire connected to an insulator and is installed on a female member of the power transmission tower and connected to the insulator. A cylinder(100) is installed on the female member so that a rear end thereof faces the insulator. A tension control instrument(200) is installed inside the cylinder to move forward and backward and includes a piston(210), gas(G), a first spring(220), and a connection member(230). A display instrument(300) includes a warning plate(320) and an elastic member(330). A light emitting lamp(400) is installed on the warning plate or the cylinder. A control unit(500) operates and controls the light emitting lamp. A sensing sensor(600) is connected to the control unit. A lock instrument(700) includes a suspension member with a projection unit(711) and a suspension projection(712), and a second spring(720). The suspension member turns on the sensing sensor in case of backing and is slidably installed on the cylinder. The second spring elastically presses the suspension member and is connected to the suspension member so that the suspension groove and the suspension projection engage with each other. A lock releasing instrument(800) includes a moving member(810) and a contact member(820). One end of the moving member is fixed on a front surface of the piston and the other end thereof is extended outside the cylinder. The contact member is moved forward and backward together with the moving member and moves the suspension member backward by pressing the projection unit in case of the backing. |
