Description

La présente invention porte sur un câble composite comportant un élément à fibre optique.The present invention relates to a composite cable comprising a fiber optic element.

Il existe déjà des câbles qui transportent à la fois de l'énergie et des informations par voie optique.There are already cables that carry both energy and optical information.

Le document EP 0 825 465 divulgue ainsi un câble d'énergie et de télécommunications, dit câble composite, comprenant un conducteur électrique et un élément à fibre optique sous la forme d'un tube métallique comportant au moins une fibre optique en surlongeur dans le tube.Document EP 0 825 465 thus discloses an energy and telecommunications, called composite cable, comprising a conductor electrical and a fiber optic element in the form of a metal tube comprising at least one optical fiber as an extension in the tube.

Le tube, en acier, est inscrit sensiblement dans un plan. Ce tube ainsi que les fibres optiques présentent des ondulations de type sinusoïdales sensiblement parallèles à ce plan. En cas de torsion du câble, le tube supporte grâce aux ondulations des allongements sans rompre et les fibres sont libérées des contraintes mécaniques.The steel tube is inscribed substantially in a plane. This tube as well as the optical fibers have sinusoidal ripples substantially parallel to this plane. If the cable is twisted, the tube supports thanks to the undulations of the elongations without breaking and the fibers are released from mechanical constraints.

L'élément à fibre optique est disposé parallèlement à l'axe longitudinal du câble entre un écran métallique par exemple en plomb recouvrant le conducteur électrique et une couche d'isolation électrique, en polymère extrudé. Cette couche est une gaine multifonctions : elle sert aussi de protection mécanique de protection contre la corrosion et assure la cohésion de l'ensemble.The fiber optic element is arranged parallel to the axis longitudinal of the cable between a metallic screen, for example made of lead covering the electrical conductor and a layer of electrical insulation, extruded polymer. This layer is a multifunctional sheath: it also serves mechanical protection corrosion protection and ensures the cohesion of the whole.

Au moment de l'extrusion de cette gaine, le polymère ne vient pas remplir les espaces entre le tube en acier et l'écran. Ce manque de matière crée des espaces s'étendant le long de l'axe longitudinal du câble. En cas de pénétration d'eau, par rupture de la gaine par exemple, ces espaces sont des chemins préférentiels pour l'eau qui va s'écouler suivant l'axe longitudinal.At the time of extrusion of this sheath, the polymer does not come fill the spaces between the steel tube and the screen. This lack of material creates spaces extending along the longitudinal axis of the cable. In case of penetration of water, by rupture of the sheath for example, these spaces are preferential paths for the water which will flow along the axis longitudinal.

L'écoulement favorise la corrosion du tube en acier et à terme celle de l'écran métallique.The flow promotes corrosion of the steel tube and ultimately that of the metal screen.

L'objet de l'invention est de pallier les problèmes précités en fournissant un câble composite protégé contre la corrosion. The object of the invention is to overcome the aforementioned problems by providing a composite cable protected against corrosion.

La présente invention propose à cet effet un câble composite comprenant :

  • un coeur entouré par un écran métallique,
  • une gaine entourant l'écran, en un matériau polymérique isolant électrique et extrudé,
  • un élément à fibre optique comprenant un tube métallique contenant au moins une fibre optique et disposé entre l'écran et la gaine,
   caractérisé en ce que l'élément à fibre optique comprend une enveloppe entourant le tube métallique et en un matériau polymérique compatible avec le matériau et en ce que le matériau polymérique de l'enveloppe est sensiblement identique audit matériau polymérique de la gaine.The present invention proposes for this purpose a composite cable comprising:
  • a heart surrounded by a metallic screen,
  • a sheath surrounding the screen, made of an electrically insulating and extruded polymeric material,
  • an optical fiber element comprising a metal tube containing at least one optical fiber and disposed between the screen and the sheath,
characterized in that the optical fiber element comprises an envelope surrounding the metal tube and in a polymeric material compatible with the material and in that the polymeric material of the envelope is substantially identical to said polymeric material of the sheath.

L'enveloppe du tube assure une meilleure protection contre la corrosion. En outre, grâce à la compatibilité entre les matériaux de l'enveloppe et de la gaine, le matériau polymérique de la gaine va se loger plus facilement dans les petits angles et ainsi réduire significativement les vides de matière, renforçant encore la lutte contre la corrosion du tube et de l'écran.The tube envelope provides better protection against corrosion. In addition, thanks to the compatibility between the materials of envelope and sheath, the polymeric material of the sheath will lodge more easily in small angles and thus significantly reduce voids of material, further strengthening the fight against corrosion of the tube and the screen.

Par ailleurs, pour former la gaine par extrusion, la température de mise en oeuvre du matériau polymérique est élevée, par exemple entre 150°C et 200°C. Le tube selon l'invention étant placé dans la tête d'extrudeuse, le matériau polymérique de son enveloppe est chauffé ce qui le rend adhérent avec le matériau polymérique de la gaine.Furthermore, to form the sheath by extrusion, the temperature of use of the polymeric material is high, for example between 150 ° C and 200 ° C. The tube according to the invention being placed in the head of extruder, the polymeric material of its envelope is heated which makes it adherent with the polymeric material of the sheath.

L'enveloppe du tube peut aussi être réalisée par extrusion.The envelope of the tube can also be produced by extrusion.

Le câble comprend en outre une couche de colle recouvrant la surface extérieure de l'écran afin de renforcer l'accrochage entre la gaine et l'écran et de diminuer le temps d'attaque par piqûres notamment et donc l'ampleur de la corrosion au niveau de l'écran. Lorsque l'élément optique est disposé directement sur l'écran, cette couche de colle assure la liaison entre l'écran et l'enveloppe polymérique de la gaine. The cable also comprises a layer of adhesive covering the outer surface of the screen in order to reinforce the attachment between the sheath and the screen and to decrease the attack time by injections in particular and therefore the extent of corrosion at the screen. When the optical element is placed directly on the screen, this layer of adhesive ensures the connection between the screen and the polymeric envelope of the sheath.

Avantageusement, le matériau polymérique de l'enveloppe du tube peut être sensiblement identique au matériau polymérique de la gaine, pour une compatibilité de matière optimisée.Advantageously, the polymeric material of the envelope of the tube may be substantially identical to the polymeric material of the sheath, for optimized material compatibility.

Dans un mode de réalisation préféré, l'écran est à base de métal choisi parmi l'aluminium et le cuivre et les matériaux polymériques de l'enveloppe et de la gaine sont en polyéthylène et de préférence en polyéthylène haute densité (PEhd).In a preferred embodiment, the screen is metal-based chosen from aluminum and copper and polymeric materials from the envelope and the sheath are made of polyethylene and preferably of high density polyethylene (HDPE).

Dans un autre mode de réalisation préféré, le câble peut comprendre en outre une couche anticorrosion recouvrant la couche de colle et en un matériau polymérique extrudé sensiblement identique au matériau polymérique extrudé de la gaine.In another preferred embodiment, the cable may include in addition an anticorrosion layer covering the adhesive layer and in a extruded polymeric material substantially identical to the material polymer extruded from the sheath.

Le tube et ladite au moins fibre optique selon l'invention peuvent présenter le long dudit câble des ondulations sensiblement parallèles à l'axe longitudinal du câble, pour obtenir les avantages techniques déjà décrits.The tube and said at least one optical fiber according to the invention can have undulations along said cable substantially parallel to the axis longitudinal of the cable, to obtain the technical advantages already described.

Les ondulations peuvent être réalisées après la fabrication de l'enveloppe du tube.The corrugations can be made after the manufacture of the envelope of the tube.

Les particularités et avantages de l'invention apparaítront clairement à la lecture de la description qui suit, faite à titre d'un exemple illustratif et non limitatif et faite en référence aux figures annexées parmi lesquelles :

  • la figure 1 représente schématiquement une vue en coupe transversale d'un câble composite dans un mode de réalisation préféré de l'invention,
  • la figure 2 représente schématiquement une vue en coupe transversale de l'élément à fibre optique inséré dans le câble composite de la figure 1,
  • la figure 3 représente schématiquement une vue partielle longitudinale et en élévation du câble composite de la figure 1.
The features and advantages of the invention will become clear on reading the description which follows, given by way of an illustrative and nonlimiting example and made with reference to the appended figures among which:
  • FIG. 1 schematically represents a cross-sectional view of a composite cable in a preferred embodiment of the invention,
  • FIG. 2 schematically represents a cross-sectional view of the optical fiber element inserted in the composite cable of FIG. 1,
  • FIG. 3 schematically represents a partial longitudinal view and in elevation of the composite cable of FIG. 1.

Les vues des figures 1 à 3 ne sont pas à l'échelle.The views in Figures 1 to 3 are not to scale.

On voit en figure 1, la section transversale d'un câble composite 10 dans un mode de réalisation préféré de l'invention, câble, par exemple enterré, de télécommunications et d'énergie, par exemple à haute tension. We see in Figure 1, the cross section of a composite cable 10 in a preferred embodiment of the invention, cable, for example buried, telecommunications and energy, for example high voltage.

Le câble composite 10, d'axe longitudinal Z, comporte un coeur 1 classique contenant par exemple un conducteur électrique isolé (non représenté), ce coeur 1 étant entouré successivement par les éléments concentriques suivants :

  • un écran métallique 2, par exemple en aluminium, obtenu par extrusion ou contre-collé ou soudure, et par exemple de 0,2 à 2 mm d'épaisseur,
  • de préférence une couche de colle extrudée 3, recouvrant la surface extérieure de l'écran 2, par exemple de 0,5 mm environ d'épaisseur,
  • de préférence une couche anticorrosion 4 recouvrant la couche de colle 3, par exemple de 0,5 mm d'épaisseur, en un matériau polymérique électriquement isolant qui est de préférence un polyéthylène haute densité et est par exemple coextrudé avec la colle 3.
The composite cable 10, of longitudinal axis Z, comprises a conventional core 1 containing for example an insulated electrical conductor (not shown), this core 1 being successively surrounded by the following concentric elements:
  • a metal screen 2, for example made of aluminum, obtained by extrusion or laminated or welded, and for example 0.2 to 2 mm thick,
  • preferably a layer of extruded glue 3, covering the outer surface of the screen 2, for example approximately 0.5 mm thick,
  • preferably an anticorrosion layer 4 covering the adhesive layer 3, for example 0.5 mm thick, made of an electrically insulating polymeric material which is preferably a high density polyethylene and is for example coextruded with the adhesive 3.

Par ailleurs, une gaine 5 servant de couche d'isolation électrique et de protection mécanique, entoure la couche anticorrosion 4 et est en un matériau polymérique extrudé identique, tel que le polyéthylène haute densité, et par exemple de 4 à 5 mm d'épaisseur en moyenne.Furthermore, a sheath 5 serving as an electrical insulation layer and mechanical protection, surrounds the anticorrosion layer 4 and is in one identical extruded polymeric material, such as high polyethylene density, for example 4 to 5 mm thick on average.

En outre, entre la couche anticorrosion 4 et la gaine 5, est disposé un élément à fibre optique 6 qui est un tube métallique enrobé contenant une pluralité de fibres optiques.In addition, between the anticorrosion layer 4 and the sheath 5, is disposed a fiber optic element 6 which is a coated metal tube containing a plurality of optical fibers.

Le tube métallique 61 est par exemple en acier inoxydable et par exemple large de 2 mm environ.The metal tube 61 is for example made of stainless steel and by example about 2 mm wide.

Ce tube 61 est enrobé, par exemple par extrusion, d'une enveloppe 62 protectrice, en un matériau polymérique compatible avec le matériau polymérique extrudé de la gaine 5 et de préférence identique, par exemple le polyéthylène ha ute densité. L'épaisseur de l'enveloppe 62 est par exemple de l'ordre de 0,5 mm.This tube 61 is coated, for example by extrusion, with an envelope 62 protective, in a polymeric material compatible with the material polymer extruded from the sheath 5 and preferably identical, for example the high density polyethylene. The thickness of the envelope 62 is for example of the order of 0.5 mm.

L'élément à fibre optique 6 est disposé sensiblement parallèlement à l'axe longitudinal Z et de préférence au plus près de l'intérieur du câble 10 afin de respecter les critères de normalisation d'épaisseur de la gaine 5 avec un minimum de matériau employé. En outre, dans un même objectif, la gaine 5 est de préférence excentrée : l'épaisseur e1 de la gaine dans la partie située au-dessus de l'élément à fibre optique 6 est sensiblement égale à l'épaisseur e2 de la gaine dans la partie opposée par rapport à l'axe Z.The optical fiber element 6 is arranged substantially parallel to the longitudinal axis Z and preferably as close as possible to the interior of the cable 10 in order to comply with the normalization criteria for sheath thickness 5 with a minimum of material used. In addition, for the same purpose, the sheath 5 is preferably eccentric: the thickness e1 of the sheath in the part located above the fiber optic element 6 is substantially equal to the thickness e2 of the sheath in the opposite part with respect to the axis Z.

Comme détaillé en figure 2, l'élément à fibre optique 6 peut contenir par exemple quatre fibres optiques FO.As detailed in FIG. 2, the optical fiber element 6 can contain for example four FO optical fibers.

Comme détaillé en figure 3, l'élément à fibre optique 6, et plus précisément le tube métallique enrobé par l'enveloppe 62, présente des ondulations 63, par exemple sinusoïdales et parallèles à l'axe longitudinal Z. A l'intérieur du tube métallique, chaque fibre optique (non représentée) présente aussi des ondulations (non représentées) qui suivant sensiblement les ondulations du tube enrobé mais sont inférieures en amplitude. Les contraintes mécaniques sur les fibres sont ainsi limitées.As detailed in FIG. 3, the optical fiber element 6, and more precisely the metal tube coated by the casing 62, has corrugations 63, for example sinusoidal and parallel to the longitudinal axis Z. Inside the metal tube, each optical fiber (not shown) also has undulations (not shown) which substantially follow the corrugations of the coated tube but are less in amplitude. The mechanical stresses on the fibers are thus limited.

Après la fabrication de l'ensemble des éléments concentriques 2, 3, 4 et notamment l'extrusion du polyéthlène pour obtenir la couche anticorrosion 4, l'élément à fibre optique 6 est posé sur cette dernière couche 4 et placé dans la tête d'extrudeuse. Lors de l'extrusion de la gaine 5, le polyéthylène mis en oeuvre vient facilement se lier avec le polyéthène de l'enveloppe 62 du tube métallique 61 et avec le polyéthylène de la couche anticorrosion 4 notamment dans les zones A, A' au voisinage de cette dernière couche 4 (voir figure 1).After the manufacture of all of the concentric elements 2, 3, 4 and in particular the extrusion of polyethylene to obtain the layer anticorrosion 4, the optical fiber element 6 is placed on this last layer 4 and placed in the extruder head. When extruding the sheath 5, the polyethylene used easily binds with the polyethylene of the casing 62 of the metal tube 61 and with the polyethylene of the layer anticorrosion 4 in particular in zones A, A 'in the vicinity of this last layer 4 (see Figure 1).

Dans une variante (non représentée), le câble 10 ne comprend pas la couche anti-corrosion 2. Avant l'extrusion de la gaine 5, l'élément à fibre optique 6 est ainsi posé sur la colle ou, en l'absence de colle, sur l'écran. Dans cette variante, la gaine 5 joue également le rôle de couche d'anticorrosion pour l'écran 5. Cette variante ne nécessite qu'une seule étape d'extrusion de polyéthylène.In a variant (not shown), the cable 10 does not include the anti-corrosion layer 2. Before the sheath 5 is extruded, the fiber element optics 6 is thus placed on the glue or, in the absence of glue, on the screen. In this variant, the sheath 5 also acts as a layer of anticorrosion for screen 5. This variant requires only one step polyethylene extrusion.

Bien entendu, la description qui précède a été donnée à titre purement illustratif. On pourra sans sortir du cadre de l'invention remplacer tout moyen par un moyen équivalent.Of course, the above description has been given as purely illustrative. Without departing from the scope of the invention, it is possible to replace any means by equivalent means.

Le câble composite selon l'invention peut comprendre une pluralité d'éléments à fibre optique selon l'invention. The composite cable according to the invention can comprise a plurality fiber optic elements according to the invention.

Le câble composite peut être monoconducteur ou multiconducteurs.The composite cable can be single conductor or Multicore.

Le câble composite peut être un câble terrestre ou sous-marin.The composite cable can be a terrestrial or submarine cable.

L'épaisseur de la gaine peut être choisie en fonction des critères de normalisation en vigueur.The thickness of the sheath can be chosen according to the criteria of standardization in force.

Le câble composite peut comprendre d'autres couches au-dessus de la gaine.The composite cable may include other layers above sheath.

L'invention peut aussi s'appliquer lorsque l'écran est à base de plomb et la gaine en polychlorure de vinyle. On adaptera alors le matériau de l'enveloppe en conséquence.The invention can also be applied when the screen is based on lead and polyvinyl chloride sheath. We will then adapt the material of envelope it accordingly.
