CONSTITUTION: A wire fixing tool(A) is detachably connected to a support unit(2) and flows the current to the transmission line when excessively pulling the transmission line. One end of the transmission line is connected to the electrode. A grip device is mounted on the other side of the transmission line and makes a worker pull the transmission line. A sensor(B) includes an alarm device(90) which is operated by receiving the power from the wire fixing device. |
