【考案の詳細な説明】
本考案は鉄塔に引留めた送電線相互を接続するジャンパ
ー線の改良に関する。[Detailed Description of the Invention] The present invention relates to improvements in jumper wires that interconnect power transmission lines held on steel towers.
従来、この種ジャンパー線としては、心線の外周に複数
層１例えば２層の撚線層を、その撚方向が互に逆方向す
なわちＳ方向とＺ方向に撚合わされたものが広汎に使用
されている。Conventionally, this type of jumper wire has been widely used, in which a plurality of layers (for example, two layers) of twisted wire layers are twisted around the outer periphery of a core wire, and the twist directions are opposite to each other, that is, the S direction and the Z direction. ing.
しかしながら、このジャンパー線は前述のように撚線層
相互の撚方向が互いに逆方向に撚合わされているから、
撚線層の素線相互は点接触となっており、素線間の摩擦
損は少く、ジャンパー線自体としての振動抑止効果が低
い。However, as mentioned above, in this jumper wire, the twisting directions of the twisted wire layers are twisted in opposite directions, so
The strands of the twisted wire layer are in point contact with each other, so there is little friction loss between the strands, and the vibration suppressing effect of the jumper wire itself is low.
従って、このジャンパー線を使用した場合には。Therefore, if you use this jumper wire.
何んらかの振動対策１例えば鉄塔とのクリアランスな大
きくする必要が生じ、そのため鉄塔建設費が嵩む等の欠
点があった。Some kind of vibration countermeasure 1, for example, it is necessary to increase the clearance with the steel tower, which has the disadvantage of increasing the construction cost of the steel tower.
また、このジャンパー線は撚線層相互の撚方向が互いに
逆になっているから、ドラムの巻きぐせかつき易く、従
ってこれの取付工事が煩雑となる欠点があった。Furthermore, since the twist directions of the twisted wire layers of this jumper wire are opposite to each other, the drum winding tends to become kinked, and therefore the installation work is complicated.
本考案は、このような欠点を改良したものである。The present invention improves these drawbacks.
これを図に示す一実施例に基づき説明する。This will be explained based on an example shown in the figure.
図は本考案になるジャンパー線の断面な示すもので１図
において１は中心線、２及び３は中心線１の上に形成し
た撚線層を示す。The figure shows a cross section of the jumper wire according to the present invention. In figure 1, 1 is the center line, and 2 and 3 are twisted wire layers formed on the center line 1.
この撚線層２及び３に工、その撚方向が同方向。The twisted wire layers 2 and 3 are twisted in the same direction.
実施例では共に２方向に撚合せてなる。In the embodiment, both are twisted in two directions.
また、このジャンパー線を構成する中心線１′は鋼撚線
、撚線層２及び３はアルミニウム撚線層からなり、その
材質は公知のものと同様であり、更にこのジャンパー線
と、鉄塔に引留められた送電線との接続構造は公知のも
のと同様である。The center line 1' constituting this jumper wire is made of steel strands, and the strands 2 and 3 are made of aluminum strands, the materials of which are the same as known ones. The connection structure with the held power transmission line is similar to a known one.
なお、上記実施例では、撚線層が２層となっているもの
を示したが、これに限られることなく。In addition, although the above-mentioned example showed the case where the twisted wire layer is two layers, it is not limited to this.
本考案は少なくとも連続する２層が同方向に撚合わされ
た多層撚線で構成してあればよい。The present invention only needs to be composed of multilayer twisted wires in which at least two consecutive layers are twisted in the same direction.
しかして本考案ジャンパー線は、これが少なくとも連続
する２層を同方向に撚合わせた多層撚線で構成されるか
ら、撚線層間の接触が線接触となり、従来の点接触のも
のに比し格段と摩擦損を大きくし得、ジャンパー線自体
としての振動抑止効果が増大し、従って鉄塔とのクリア
ランスな大きくする必要がなく、それだけ鉄塔建設費が
低減される。However, since the jumper wire of the present invention is composed of a multi-layer stranded wire in which at least two consecutive layers are twisted in the same direction, the contact between the stranded wire layers is a line contact, which is much more effective than the conventional point contact. This increases the friction loss and increases the vibration suppression effect of the jumper wire itself.Therefore, there is no need to increase the clearance with the tower, and the tower construction cost is reduced accordingly.
また、撚線層相互の撚方向が同一であるから。Also, the twisting directions of the twisted wire layers are the same.
ドラムの巻きぐせかつきにくいため、その取付工事を極
めて容易に行い得る等の効果を奏する。Since the drum is not easily curled, the installation work can be carried out extremely easily.
図は本考案ジャンパー線の一実施例を示す断面図である
