The present invention relates to a transmission line sag prevention device, and more particularly, by connecting the upper and lower insulation plate formed with a mounting groove for mounting the transmission line with a spring and a hinge to prevent the transmission line sag due to wind or temperature change. In addition to the line, it is possible to firmly fix the transmission line mounted on the mounting groove by constituting the transmission line fixture fastened by the spring to the mounting groove of the upper and lower insulation plates, and further comprises a sliding stopper on both sides of the upper and lower insulation plates. The present invention relates to a transmission line sag preventing device that prevents the upper and lower insulating plates from being separated from each other when the lower and insulating plates flow together.

In general, electric power is transferred from the power plant to the substation, after several stages of transformation, and then to the customer through the pole transformer of the pole of the pole along the distribution line such as concrete pole.

In addition, the high-voltage cable of each pole of the customer side is wired to have a tension of the upper support tensioned to the top of the pole, and is connected to the jumper wire upward or downward through a line post insulator fixed to the upper support.

As such, transmission lines are used as a means of transmitting power from substations, and a plurality of steel towers for supporting the transmission lines are installed in mountains or plains to connect a plurality of transmission lines to each other.

These transmission lines are installed under conditions where vibrations or amplitudes are likely to occur due to climatic influences such as wind or snow rain due to the nature of being installed at high altitudes, and especially when the strong wind blows, the transmission lines vibrate up and down severely. If friction occurs, it may cause a large safety accident such as short circuit or power failure.

Therefore, conventionally, a transmission line deflection prevention device is installed on a transmission line at a predetermined distance to prevent the transmission lines from colliding with each other.

The transmission line sag prevention device is a plurality of transmission line clamping radially coupled to one frame at a predetermined interval, each clamping is a structure that allows the operator to selectively bolt or detach the frame to the worker to perform long-term hard work at high altitude As described above, the work must be very cumbersome and the work time must be elapsed since the installation of the transmission line must be performed while replacing the tool with the dedicated tool carried as described above.

In addition, the conventional transmission line sag prevention device has only a simple function of maintaining only a certain distance interval between transmission lines, so that the degree of deflection of the transmission line through the naked eye has a problem of low reliability and can not cope quickly.
