る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an overhead wiring method for overhead power transmission lines, etc.
0 regarding & Conventionally, as shown in Figure ls1, a connecting device 5. consisting of insulators 2, 2, brackets S, Z, and clamps 4.4 is used between support towers 1, such as steel towers, erected at predetermined intervals. 5 [3
As shown in Figure 2, spacers # that connect the electric wire 6 and the extension wires R and T are scattered at predetermined intervals.

。The reason for adding a space is to make the extension wire 2 close to the wire to make it a multi-conductor, and to lower the surface tilt of the wire dO to prevent the generation of corona. In addition, the extension wire 7 is constructed with a tension lower than that of the electric wire 411g so that the strength of the support towers 1 and 10 is not exceeded.

方法【提供するもむである。However, in the method of installing the electric wire 6 and the extension wire 7 between the support towers 1 and 1 and then connecting them with the spacer 8, the spacer 8 acts to lift the extension wire 7, so the extension wire 7 The tension becomes even smaller than that before the spacer 8 is deposited. As a result, the attachment wire 1 is installed with more slack than necessary from the electric wire C between the spacers 8, and the distance between the electric wire 6 and the attachment wire 1 becomes excessive. Therefore, the surface slope of the electric wire 60 does not decrease, and corona still occurs. The present invention has been made in view of the above-mentioned problems, and it is possible to install the wire in parallel with the electric wire without causing the wire to slacken significantly, thereby reliably preventing the occurrence of corona. This is the method we provide for overhead wires.

The distance between the attachment wire 1g and the electric wire r is maintained at a predetermined value, and the slope of the surface of the electric wire 70 is reliably lowered to prevent the generation of corona. It can be easily installed parallel to the line, which can reliably prevent the occurrence of cosena.
