本考案は、多相多線式線路ケーブルの改良に関するもの
である。[Detailed Description of the Invention] The present invention relates to an improvement of a multi-phase multi-wire line cable.
従来一般に採用されている多相多線式線路ケーブルとし

軸的に且つ相互に絶縁して配置して成る所謂多層同軸型
ケーブル或は各相をそれぞれ独立した単心ケーブルを以
って構成する所謂多心撚合型ケーブルがある。Conventionally commonly used multi-phase multi-wire line cables include so-called multi-layer coaxial cables in which conductors constituting each phase of a multi-phase multi-wire line are arranged coaxially and insulated from each other. There is a so-called multi-core twisted type cable in which each phase is constructed with an independent single-core cable.
然るに、前者においては誘導による電力損失が小さいと
言う利点がある反面その製造がきわめて面倒となること
から価格がかなり高くなるという難点があり、又後者に
おいては価格は比較的安価であるものの誘導による電力
損失が比較的大きいという難点がある。However, while the former has the advantage that the power loss due to induction is small, it has the disadvantage that it is extremely troublesome to manufacture and is therefore quite expensive, while the latter has the disadvantage that although the price is relatively low, it is The disadvantage is that the power loss is relatively large.
このように従来一般に採用されているこの種ケーブルに
おいては、そのいずれも一長一短を有し、その改善が早
くから望まれていた。As described above, these types of cables that have been commonly used in the past have both advantages and disadvantages, and improvements have been desired for a long time.
本考案は上述の点に鑑がみて為されたものであって、価
格並びに誘導による電力損失の両面において優れた所望
の多相多線式線路ケーブルの提供を目的とし、その要旨
とするところは任意な線材を軸としてその周囲に、多相
多線式線路の各相を構成する複数本の導体を断面円状に
且つ相互に絶縁して配置して戒り、上記複数本の導体の
中の同相を構成する複数本の導体は、当該任意な線材の
外部円周線上において互いに均等な間隔で分散して配置
されて成る点にある。The present invention was developed in view of the above points, and aims to provide a desired multi-phase multi-wire line cable that is excellent in terms of both cost and power loss due to induction, and its gist is as follows: A plurality of conductors constituting each phase of a multi-phase multi-wire line are arranged around an arbitrary wire material with a circular cross section and mutually insulated, and among the plurality of conductors mentioned above, The plurality of conductors constituting the same phase are distributed and arranged at equal intervals on the outer circumferential line of the arbitrary wire.
次に添付の図面を参照し乍ら本考案の実施例を説明する
が、本考案が本実施例を以って限定的に解釈されるもの
でないことは言うまでもない。Next, embodiments of the present invention will be described with reference to the accompanying drawings, but it goes without saying that the present invention is not to be construed as limited by the embodiments.
本実施例以外にも幾つかの実施例が想到されよ・うが、
それらが本質的に本考案の技術範囲内に属する以上、勿
論それらは本考案の一部である。Although several embodiments other than this embodiment may be conceived,
As long as they are essentially within the technical scope of the present invention, they are of course part of the present invention.
まず、第１図において、１，２．３は三層三線式線路に
