本考案は架空ケーブル用メツセンジ−ワイヤーの改良に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in mesh wires for overhead cables.
従来、架空ケーブル用メツセンジャーワイヤーとしては
、鋼線等の金属線を撚り合わせた金属撚線が使用されて
いる。Conventionally, stranded metal wires made by twisting metal wires such as steel wires have been used as mesh wires for overhead cables.
このメツセンジャーワイヤーは第１図に示す如く、メツ

シングワイヤー３で縛り、メツセンジャーワイヤー１に
架空ケーブル２を吊下するために使用するものである。As shown in FIG. 1, this metsenger wire is used for suspending the overhead cable 2 attached to the metsenger wire 1 by tying it with a lashing wire 3.
しかし、従来のように金属撚線のメツセンジャーワイヤ

ラッシングワイヤーの巻付けが所定のピッチで行い難い
という問題があり、また該メツセンジャーワイヤーと架

がメツセンジャーワイヤーに沿って滑り、架空ケーブル
に応力集中個所が生ずるという問題があった。However, when using conventional metal stranded metsenger wire, the lashing wire slips on the metsenger wire when wrapping the lashing wire.
There is a problem in that it is difficult to wind the lashing wire at a predetermined pitch, and the frictional resistance at the contact area between the metsenger wire and the sheath (polyvinyl chloride sheath, etc.) on the surface of the overhead cable is small, and if the lashing wire loosens, There is a problem in that an overhead cable installed with a catenary slides along the metsenger wire, creating stress concentration points in the overhead cable.
本考案は上記問題点に鑑みてなされたもので、ラッシン

架空ケーブル用メツセンジャーワイヤーを提供するもの
で、金属撚線上に摩擦抵抗増大用の被覆層を設け、該摩
擦抵抗増大用の被覆層には長手方向に沿って多数の水抜
孔を設けたことを特徴とするものである。The present invention was developed in view of the above problems, and provides a metsenger wire for overhead cables that prevents the slipping of the lashing wire and the slipping of the overhead cable. The coating layer for increasing frictional resistance is characterized in that a large number of drainage holes are provided along the longitudinal direction.
本考案の一実施例を第２図および第３図を参照して詳細
に説明するに、１０は金属撚線で、亜鉛メッキ鋼線や亜
鉛メッキ鉄線等を撚り合わせたものでなる。One embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3. Reference numeral 10 denotes a metal stranded wire, which is made of twisted galvanized steel wire, galvanized iron wire, or the like.
１１は金属撚線１０の外周に設けたポリ塩化ビニル等の
摩擦抵抗増大用の被覆層で、該被覆層は第２図に示す如
く押出しによって設けてもよく、また第３図に示す如く
テープ巻きによって設けてもよい。Reference numeral 11 denotes a coating layer made of polyvinyl chloride or the like provided on the outer periphery of the stranded metal wire 10 to increase frictional resistance.The coating layer may be provided by extrusion as shown in FIG. 2, or may be provided by tape as shown in FIG. It may also be provided by winding.
１２は被覆層１１の長手方向に沿って多数設けられた水
抜孔である。Reference numeral 12 denotes a large number of drainage holes provided along the longitudinal direction of the coating layer 11.
この水抜孔１２は第２図の如く押出した被覆層の場合に
は被覆層形歳時またはその後に設ければよく、ま第３図
に示す如くテープ巻きて被覆層を形成する場合は穴開き
テープを使用すればよい。In the case of an extruded coating layer as shown in FIG. 2, this drainage hole 12 may be provided at or after the coating layer is formed, or if the coating layer is formed by wrapping tape as shown in FIG. 3, a hole is provided. You can use tape.
上記のように本考案に係る架空ケーブル用メツセンジャ
ーワイヤーは、金属撚線上に摩擦抵抗増大用の被覆層を
設けたため、該メツセンジャーワイヤーとラッシングワ
イヤー並びに架空ケーブル表面との接触部の摩擦抵抗が
従来のものより大きくなる。As mentioned above, since the metsenger wire for an overhead cable according to the present invention has a coating layer for increasing frictional resistance on the stranded metal wire, the frictional resistance of the contact portion between the metsenger wire, the lashing wire, and the surface of the overhead cable is reduced. It is larger than the conventional one.
このためラッシングワイヤーがメツセンジャーワイヤー
上を滑りにくくなるのでラッシングワイヤーを所定のピ

ンジャーワイヤーに沿って滑りにくくなり、架空ケーブ
ルに応力集中個所が生じるのを防ぐことができる。This makes it difficult for the lashing wire to slip on the messenger wire, allowing the lashing wire to be wound at a predetermined pitch, and also prevents the overhead cable from sliding along the messenger wire, preventing stress concentration points from occurring on the overhead cable. It can be prevented.
また本考案に使用するメツセンジャーワイヤーは、摩擦
抵抗増大用の被覆層に水抜孔が設けであるため、引留部
等から絶縁層内に氷が浸入しても該水は水抜孔から容易
に流れ出る。In addition, the Metsenger wire used in this invention has a drainage hole in the coating layer to increase frictional resistance, so even if ice enters the insulation layer from the retaining part, the water can easily flow out from the drainage hole. .
このため金属撚線が腐食断線することなく長期間安定し
て使用できる等の利点を有する。Therefore, the metal strands have advantages such as being able to be used stably for a long period of time without corrosion and disconnection.
