ヤロープが破断する危険性がある。 Normally, when installing an overhead power transmission line such as ACSR between steel towers, a wire rope is first connected to the overhead power transmission line as a pull wire, and the wire rope is pulled through a metal wheel installed on the tower. Install electric wires between each tower. In this case, since the wire rope is generally coated with oil such as grease, the grease will adhere to the metal wheel, and the grease will also adhere to the surface of the overhead power transmission line that follows through the metal wheel. Become. If an overhead power transmission line is installed with oil such as grease attached to its surface, when it rains, raindrops will adhere to and remain on the area, causing corona discharge starting from the raindrops and causing corona noise. Therefore, it is desirable to avoid oils from adhering to the surface of power transmission lines as much as possible. In order to avoid oil from adhering to the surface of the power transmission line, if a wire rope that is not coated with grease is used, when the power transmission line is towed, the friction between each strand of the wire rope will increase, and the wire There is a risk of the rope breaking.
本考案は上記の点に鑑み、ひきワイヤとしての

のである。 In view of the above points, the present invention aims to provide a pulling wire that functions as a pulling wire and does not allow oil to adhere or remain on overhead power transmission lines. It is characterized by having its outer periphery coated with rubber or plastic.
以下、本考案の架空送電線のひきワイヤにつき
図面より詳述する。 The overhead transmission line pull wire of the present invention will be described in detail below with reference to the drawings.

覆し得る。 The attached figure is a cross-sectional view showing one embodiment of the drawn wire of the overhead power transmission line of the present invention, in which 1 is a wire made of hemp, juute, polypropylene, etc. that constitutes the core network of the wire rope, and 2 is a wire arranged on the core network. 3 is each of the above-mentioned strands 1 and 2.
It is oil such as grease that is impregnated between each. Reference numeral 4 denotes a rubber or plastic layer coated on the outer periphery of the wire rope, and the rubber or plastic coating can be coated onto the wire rope using a conventional extruder.

騒音の懸念がない。 The pulling wire of the overhead power transmission line of the present invention has the above-mentioned configuration, and since oil such as grease is contained between each strand of the wire rope, when the overhead power transmission line is towed, it is difficult to avoid friction between the strands. There is no risk of the wire rope breaking, and it functions as a pulling wire.The outer periphery of the wire rope is coated with rubber and plastic, so oil from the wire rope does not reach the surface of the overhead power transmission line through the metal wheel. Since there is no adhesion, there is no concern about corona noise from overhead power transmission lines after the overhead power lines are installed.
尚、本考案のワイヤロープの素線構成は図に示

採用し得る。 Note that the wire configuration of the wire rope of the present invention is not limited to that shown in the figure, and for example, JIS
G 3525 (1977) may be adopted as appropriate.
