【発明の詳細な説明】
本発明は電力ケーブルの扇形導体の製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing sector conductors for power cables.
電力ケーブルでは導体を分割導体とするため、
撚り合わせた複数の素線よりなる導体を扇形にプ
レフオームすることが知られている。 In power cables, the conductors are divided conductors, so
It is known to preform a conductor consisting of a plurality of twisted wires into a fan shape.
このプレフオームは導体を直状の正扇形柱とす
るのではなく、撚り合わせ方向に沿つて螺旋状に
ねじれた形に構成している。 In this preform, the conductor is not formed into a straight regular fan-shaped pillar, but is formed into a spirally twisted shape along the twisting direction.
このような扇形導体の製造速度（引取速度）は
撚線機の回転速度によつて制限されていた。 The manufacturing speed (take-off speed) of such sector-shaped conductors has been limited by the rotational speed of the wire twisting machine.
本発明は斯かる状況に鑑み、同じ回転数の撚線
機を用いて従来より製造速度を高めることのでき
る扇形導体の製造方法を提供することを目的とす
る。 In view of this situation, it is an object of the present invention to provide a method for manufacturing sector-shaped conductors that can increase the manufacturing speed compared to the conventional method using a wire twisting machine with the same number of rotations.
本発明の構成を、一実施例を示す図面を参照し
て具体的に説明する。 The configuration of the present invention will be specifically explained with reference to the drawings showing one embodiment.
第１図において、ラインには撚線機２，２′と
圧縮プレフオーム装置１，１′とが交互に配置さ
れ、導体の下層から順次所定寸法に各層を仕上げ
て行く。 In FIG. 1, wire twisting machines 2, 2' and compressed preform devices 1, 1' are arranged alternately on the line, and each layer of the conductor is finished to a predetermined size in sequence starting from the lower layer.
まず、下層の導体素線４を撚線機２によつて撚
り合わせ、これを圧縮ロールを回転する圧縮プレ
フオーム装置１に送り込む。この圧縮ロールは撚
線方向と逆の向きに回転させる。 First, the conductor wires 4 in the lower layer are twisted together by the twisting machine 2, and then fed into the compression preform device 1 which rotates compression rolls. This compression roll is rotated in a direction opposite to the direction in which the wires are stranded.
これによつて、素線は撚線機で撚つたピツチよ
り20〜30％縮むので、予めこの縮む20〜30％分を
見込んだ長いピツチに撚り合わせておけば、結果
として撚線のピツチは設定通りのピツチとなる。 As a result, the wires will shrink by 20 to 30% compared to the pitch twisted with the wire twisting machine, so if you twist the wires to a long pitch that allows for this 20 to 30% shrinkage in advance, the pitch of the stranded wires will be reduced by 20 to 30%. The pitch will be as per the setting.
上層の導体素線４′は撚線機２′によつて下層の
導体素線４とは逆の向きに撚り合わせられ、さら
にその撚り合わせ方向と逆の向きに圧縮プレフオ
ーム装置１′によつてプレフオームされる。 The conductor strands 4' of the upper layer are twisted in the opposite direction to the conductor strands 4 of the lower layer by the twisting machine 2', and are further twisted by the compression preform device 1' in the opposite direction to the twisting direction. Preformed.
このようにして多層撚り合わせられた扇形導体
５が製造される。３，３′はボビンである。 In this way, a multilayer twisted sector conductor 5 is manufactured. 3 and 3' are bobbins.
この扇形導体を組合わせて見かけ上、丸い電力
ケーブルの導体としたものを第２図に示す。 FIG. 2 shows a combination of these fan-shaped conductors to form an apparently round power cable conductor.
第２図においてＡは素線の撚り方向を、Ｂはプ
レフオームの撚り方向を示している。 In FIG. 2, A indicates the direction in which the wires are twisted, and B indicates the direction in which the preform is twisted.
本発明の製造方法によれば、撚線機の回転数及
び撚線のピツチを変えることなく、引取速度すな
わち製造速度を20〜30％も高めることができるも
のである。 According to the manufacturing method of the present invention, the take-up speed, that is, the manufacturing speed, can be increased by as much as 20 to 30% without changing the rotational speed of the wire stranding machine or the pitch of the strands.
