Description
【発明の詳細な説明】 本発明は電力ケーブルの製造方法に関する。[Detailed description of the invention] The present invention relates to a method of manufacturing a power cable.
近年、送電容量の増加とともに電力ケーブルの導体サイ
ズは大型化の一途を辿つている。分割導体はこのような
大型電力ケーブルにおいては、表皮効果を低減させるた
めの必要不可欠な手段となつている。In recent years, as power transmission capacity increases, the conductor size of power cables continues to increase in size. Split conductors have become an essential means to reduce skin effect in such large power cables.
しかしさらに大型化が進むにつれて、分割されたセグメ
ントにおける表皮効果の問題が顕著となつてきた。However, as size increases, the skin effect problem in the divided segments becomes more prominent.
過去にアイデアとしては、セグメント内の導体素線の１
本１本を絶縁線例えばエナメル線とする案が提示されて
いる。In the past, the idea was that one of the conductor strands in the segment
A plan has been proposed in which each wire is an insulated wire, such as an enameled wire.
ところが素線をエナメル線とした場合には、表皮効果の
低減は達成できるが、ケーブルの接続が困難であり、従
来の接続工法をそのまま適用することができず、しかも
素線価格が大幅に高価なものとなつてしまう欠点があつ
た。However, when using enamelled wire as the wire, the skin effect can be reduced, but it is difficult to connect the cable, and conventional connection methods cannot be applied as is, and the cost of the wire is significantly higher. It had the drawback of becoming a thing.
本発明は斯かる状況に鑑み、表皮効果の低減が果せかつ
従来の接続工法の適用が可能な電力ケーブルの製造方法
を提供することを目的とする。SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a method for manufacturing a power cable that can reduce the skin effect and allow application of conventional connection methods.
本発明の構成を、実施例を示す図面を参照して具体的に
説明する。図において、１は導体素線であり、複数本撚
り合わせられている。The configuration of the present invention will be specifically explained with reference to drawings showing embodiments. In the figure, reference numeral 1 indicates a conductor element wire, and a plurality of conductor wires are twisted together.
その外側には絶縁テープ２を巻回しいわゆる分割導体の
セグメント３を構成する。これら導体セグメント３をい
くつか（普通４〜６本）撚り合わせるが、その撚り合わ
せ方向を矢印４のように導体素線１の撚り合わせ方向（
矢印５）と反対方向とする。An insulating tape 2 is wound around the outside to form a so-called divided conductor segment 3. Several (usually 4 to 6) of these conductor segments 3 are twisted together, and the direction of the twisting is as shown by the arrow 4 in the direction of the twisting of the conductor strands 1 (
The direction is opposite to arrow 5).
絶縁テープ２は必ずしも全ての導体セグメント３に施さ
れている必要はない
この上に絶縁体、シース、防蝕層などが施される。The insulating tape 2 does not necessarily need to be applied to all the conductor segments 3; an insulator, sheath, anti-corrosion layer, etc. can be applied thereon.
このように反対方向に撚り合わせると、はじめに撚り合
わせた導体素線１に対し若干撚り戻す力クが加わり、い
わゆる笑いが生じ導体素線１間にわずかの間隙が生じる
。When the conductor wires 1 are twisted in opposite directions in this manner, a slight untwisting force is applied to the conductor wires 1 which are first twisted together, resulting in so-called "litter" and a slight gap is created between the conductor wires 1.
そうなると、導体素線１間の接触抵抗が全体的に大きく
なり、あたかも導体素線１間に絶縁体を介在したような
作用をする。In this case, the contact resistance between the conductor wires 1 increases as a whole, and the conductor wires 1 act as if an insulator was interposed between them.
５ そして接続部においては導体全体を締付けることに
より、格別皮むきなどを行なうことなく容易に接続でき
るものである。5. At the connection part, by tightening the entire conductor, the connection can be easily made without special peeling.
すなわち本発明方法によれば、表皮効果の低減が得られ
ると共に接続における支障も発生しないものである。That is, according to the method of the present invention, the skin effect can be reduced and no trouble occurs in connection.
１面の簡単な説明 図は本発明の一実施例を示す説明図である。Brief explanation of page 1 The figure is an explanatory diagram showing one embodiment of the present invention.
