  Câble creux pour lignes   électriques à   haute tension. on connaît   déj   un câble creux dans lequel on utilise com- me organe de support un corps profilé dont la forme de la sec- tion transversale s'écarte de la forme circulaire et qui est tordu autour de son axe médian de façon que les bords du corps profilé et les fils da câble fassent au point d'appui un an- gle aussi grand que possible et que la distance entre deux points d'appui soit aussi petite que possible.

     L'emploi   d'un semblable câble a été proposé comme câble pour navires, comme   corde .   linge, comme paratonnerre, etc, 

 <Desc/Clms Page number 2> 

 
La présente invention repose sur la constatation qu'un sem- blable câble convient également pour la transmission de courants électriques, en particulier pour les courants de haute tension, pour lesquels le diamètre du câble doit être augmenté   artifi..     ciellement   pour supprimer les effets de couronne qui se   produis   sent, La présente invention a donc pour objet l'emploi de ce   ca..   ble connu dans une application nouvelle, savoir pour les lignes électriques à haute tension, 
La   for.ie   du profil de l'organe de support peut être quelcon- que,

   par exemple polygonale (rectangulaire, en losange ou en   é-   toile) ou elliptique. Le corps de support peut, suivant le choix de la matière, servir en marne   tenps   d'organes de traction ou éga- lement de conducteur de courant ou remplir encore ces deux fonc- tions à la fois. Pour augmenter la résistance la traction du câble creux, on peut toutefois disposer, suivant la présente in- vention, sur le corps de support des fils de support, par   exem-   ple en acier, en fer, ou en bronze, qui sont câblés sur le,corps profilé tordu ou sont placés dans les spires de ce dernier. 



   Le dessin représente différents exemples de réalisation de l'invention. on a désigné é a la fig. 1 par ll les fils de ligne qui sont câblés sur le corps de support 12 qui est tordu de la manière décrite autour de son axe longitudinal, le câblage se faisant dans un sens opposé au pas du corps de support. Les fig. 



    2 à 4   sont des coupes transversales dans des câbles creux   sui-   vant la présente invention et montrent différentes formes du pro- fil de l'organe de support. La fig. 5 montre un conducteur creux dans lequel on a câblé sur l'organe de support   12   une couche de fils de support, et sur celle-ci seulement les fils de ligne pro- prement dits 11. Dans les formes de réalisation des fig. 6 et 7, les fils de support 13, qui peuvent servir à a fois de ligne faible courant, sont placés dans les spires du corps profilé tor- du 12.

  Hollow cable for high voltage power lines. a hollow cable is already known in which a profiled body is used as the support member, the shape of the cross section of which deviates from the circular shape and which is twisted around its central axis so that the edges of the profiled body and the cable wires make the fulcrum as large an angle as possible and the distance between two fulcrums is as small as possible.

     The use of a similar cable has been proposed as a cable for ships, as a rope. linen, as a lightning rod, etc,

 <Desc / Clms Page number 2>

 
The present invention is based on the observation that a similar cable is also suitable for the transmission of electric currents, in particular for high voltage currents, for which the diameter of the cable must be artificially increased in order to suppress the effects of crown which occurs feels, The present invention therefore relates to the use of this known ca .. ble in a new application, namely for high voltage power lines,
The for.ie of the profile of the support member can be any,

   for example polygonal (rectangular, rhombus or star) or elliptical. The support body can, depending on the choice of material, serve as traction members or also as a current conductor, or else fulfill these two functions at the same time. In order to increase the tensile strength of the hollow cable, it is however possible, according to the present invention, to place on the support body support wires, for example of steel, iron or bronze, which are cabled on the, profiled body twisted or are placed in the turns of the latter.



   The drawing represents various embodiments of the invention. e has been designated in FIG. 1 through ll the line wires which are cabled on the support body 12 which is twisted in the manner described about its longitudinal axis, the cabling being in a direction opposite to the pitch of the support body. Figs.



    2-4 are cross-sections in hollow cables according to the present invention and show different shapes of the profile of the support member. Fig. 5 shows a hollow conductor in which has been wired on the support member 12 a layer of support wires, and thereon only the so-called line wires 11. In the embodiments of FIGS. 6 and 7, the support wires 13, which can serve as both a low current line, are placed in the turns of the tor- profiled body 12.
