Generally, high power transmission T1. In the line, an overhead ground wire is installed above the left and right lines, in other words, an overhead ground wire is installed above the lines, but in recent years, as shown in Figure 7, for example, overhead ground wires with optical fiber It is becoming increasingly common for ground lines 1 and 9 additional ground lines to be added. In addition, 2 is a steel tower, 3 is a power transmission line, and each turn is arranged on the steel tower 2 side. 4 indicates the existing overhead ground wire. This new Nitji line 1 is usually installed near the center upper end of the steel tower 2, but the conventional method for installing new extensions is to stop the power transmission lines of both circuits or one circuit, and Protective scaffolding should be installed at locations where lines, special high-voltage lines, roads, etc. ,l
, H is constructed, a mensenger rope is extended using a helicopter, etc., and a ribbed and ground wire is connected to this mensenger rope and then the wire is extended. However, in such a method, 1'f? It takes a great deal of effort and expense to construct the line, and it is difficult to stop both lines due to the large impact it will have. has the disadvantage that it is located on the 1st floor, making it extremely difficult to move it to the center.

According to the method of the present invention explained above, when extending a new grassland line, the wire 1 and the net type gold wheel are placed between the two towers using the existing overhead ground wires on the left and right, so that if the new grassland line is extended, Even if the ground wire breaks the wire, the net-type gold wheel will stop the uke. Therefore, there is no need to install cavity-proof scaffolding at the places where conventional J41 (tii Ground #+i H: The line is pulled by the Metsusenja rope and moved parallel to the power transmission line, and is extended between the inner towers, so that it is passed over the existing overhead ground wires on the left and right.
The central ductile stop of the net-type metal wheel was
Since the center position of the one-pronged overhead land multi-unit RN is moved and the line is extended, it is possible to perform a 1'o operation with both lines of the power transmission line in a live state, and the line extension car part of the net type metal car can be carried out. Since the wire is stretched in a supported state, the wire is stretched with low tension.
