Abstract
Description
L'invention concerne les câbles de transport d'énergie et de télécommunications structurellement renforcés par incorporation d'au moins un fil de renfort et/ou d'une armure composée d'une ou de plusieurs couches de fils.The invention relates to cables for transporting energy and structurally reinforced telecommunications by incorporating at least one wire reinforcement and / or armor composed of one or more layers of son.
Comme il est connu de nombreux câbles de transport d'énergie et de télécommunications sont structurellement renforcés afin de mieux résister aux contraintes physiques qui sont susceptibles de leur être appliquées dans le milieu où ils sont installés. Ceci se traduit par l'association d'un ou de plusieurs fils de renfort aux fils électriquement conducteurs et/ou aux guides d'ondes de transmission optique, dans le cas de câbles aériens, pour améliorer les performances de ces câbles sur le plan mécanique et en particulier en matière de résistance à la rupture. D'une manière analogue, il est classique de renforcer mécaniquement les câbles terrestres et notamment ceux destinés à être enterrés, ainsi que les câbles sous-marins, par une armure composée d'une ou de plusieurs couches de fils plus résistants mécaniquement que les fils électriquement conducteurs, et/ou les guides d'onde de transmission que l'armure entoure.As is known from numerous cables for transporting energy and telecommunications are structurally reinforced in order to better resist physical constraints that are likely to be applied to them in the environment where they are installed. This results in the association of one or more reinforcing wires electrically conductive wires and / or transmission waveguides optical, in the case of overhead cables, to improve the performance of these cables in mechanical terms and in particular in terms of breaking strength. Similarly, it is conventional to mechanically reinforce cables terrestrial and in particular those intended to be buried, as well as submarine cables, by armor made up of one or more layers of more mechanically resistant than electrically conductive wires, and / or guides transmission wave that the armor surrounds.
Les fils de renfort et les fils d'armure des câbles de transport d'énergie et de télécommunications peuvent être réalisés en acier inoxydable, de manière à profiter des qualités mécaniques susceptibles d'être obtenues avec ces aciers et de leur tenue en matière de corrosion. En effet, une grande résistance à la corrosion est indispensable, en particulier dans le cas des câbles sous-marins qui sont placés dans une milieu corrosif, ainsi que dans le cas des câbles souterrains et des câbles aériens soumis à des contraintes climatiques difficiles. Le document EP-A-710862 décrit ainsi un câble sous-marin à fibres optiques comportant des fils de renfort en acier inoxydable.The reinforcing wires and the armor wires of the cables for transporting energy and telecommunications can be made of stainless steel, so as to benefit mechanical qualities likely to be obtained with these steels and their behavior in terms of corrosion. Indeed, a high resistance to corrosion is essential, especially in the case of submarine cables which are placed in a corrosive environment, as well as in the case of underground cables and cables aerials subject to difficult climatic constraints. Document EP-A-710862 thus describes an optical fiber submarine cable comprising reinforcing wires in stainless steel.
Toutefois l'utilisation de l'acier inoxydable pour la réalisation de fils de renfort ou d'armure se traduit par une augmentation significative du coût des câbles et des solutions de substitution moins onéreuses sont donc recherchées.However, the use of stainless steel for the production of reinforcement or armor results in a significant increase in the cost of cables and less expensive alternatives are therefore sought.
Il est connu de substituer d'autres fils, notamment en acier galvanisé ou en acier protégé par un revêtement en aluminium, aux fils en acier inoxydable pour réduire les coûts. Toutefois, la résistance à la corrosion obtenue est nettement moindre et le dégagement éventuel d'hydrogène, apparaissant notamment dans le cas de fils en acier galvanisé, empêche l'exploitation de ces fils pour la constitution de coeurs de câbles optiques de télécommunications. It is known to substitute other wires, in particular galvanized steel or steel protected by an aluminum coating, with stainless steel wires for lower the costs. However, the corrosion resistance obtained is clearly less and the possible release of hydrogen, appearing in particular in the case of galvanized steel wires, prevents the exploitation of these wires for the constitution of optical telecommunication cable cores.
L'invention propose donc un câble de transport d'énergie ou de télécommunications structurellement renforcé par incorporation d'au moins un fil de renfort et/ou d'une armure comportant une ou plusieurs couches de fils.The invention therefore provides a cable for transporting energy or structurally reinforced telecommunications by incorporating at least one wire reinforcement and / or armor comprising one or more layers of son.
Selon une caractéristique de l'invention, le câble comporte au moins un fil de renfort ou d'armure constitué en un acier composite à coeur en acier, d'un type standard, recouvert d'une couche d'acier inoxydable.According to a characteristic of the invention, the cable comprises at least one wire reinforcement or armor made of a composite steel with a steel core, of a type standard, covered with a layer of stainless steel.
Selon une caractéristique d'une variante de l'invention, le câble comporte au moins une couche d'armure constituée de fils en acier composite.According to a characteristic of a variant of the invention, the cable comprises at minus a layer of armor made of composite steel wires.
Selon une caractéristique d'une variante de l'invention, le câble comporte au moins un fil de renfort ou d'armure constitué en acier composite de marque déposée NUOVINOX.According to a characteristic of a variant of the invention, the cable comprises at at least one reinforcing or armouring wire made of registered trademark composite steel NUOVINOX.
Selon une caractéristique d'une variante de l'invention, le câble comporte un tube obtenu à partir d'un feuillard constitué en un acier composite ayant un coeur en acier, d'un type standard, recouvert d'une couche d'acier inoxydable.According to a characteristic of a variant of the invention, the cable comprises a tube obtained from a strip made of a composite steel having a core of steel, of a standard type, covered with a layer of stainless steel.
Selon une caractéristique d'une variante de l'invention, le câble comporte un tube constitué en acier composite de marque déposée NUOVINOX.According to a characteristic of a variant of the invention, the cable comprises a tube made of NUOVINOX registered brand composite steel.
L'invention, ses caractéristiques et ses avantages sont précisés dans la description qui suit en liaison avec les figures évoquées ci-dessous.The invention, its characteristics and its advantages are specified in the description which follows in conjunction with the figures mentioned below.
La figure 1 propose une vue en coupe transversale d'un exemple d'un câble de télécommunications à structure renforcée.Figure 1 provides a cross-sectional view of an example of a cable telecommunications structure.
La figure 2 propose une vue d'un tronçon d'un exemple de câble de transport d'énergie à structure renforcée.Figure 2 provides a view of a section of an exemplary cable energy transport with reinforced structure.
L'exemple de câble de télécommunications dont une coupe transversale est illustrée en figure 1, est un câble aérien à fibres optiques, dit câble de garde optique, tel que mis en oeuvre dans les réseaux de distribution électrique à haute tension à des fins de télésurveillance, téléconduite et/ou télécommunications. Il est prévu pour être porté par les pylônes du réseau de transport d'énergie électrique et susceptible en conséquence d'être soumis à des conditions climatiques rigoureuses.The example of a telecommunications cable with a cross section is illustrated in FIG. 1, is an aerial fiber optic cable, called the guard cable optics, as implemented in high power distribution networks voltage for telesurveillance, telecontrol and / or telecommunications purposes. It is intended to be carried by the pylons of the electrical energy transport network and may therefore be subject to harsh climatic conditions.
Ce câble de garde comporte un fil de renfort central 1 autour duquel sont
disposés des tubes câblés 2 renfermant chacun un groupe de fibres optiques 3. les
tubes câblés sont placés entre le fil de renfort central 1 et un tube de maintien 4. Ce
tube est usuellement réalisé en métal, en alliage métallique ou en matériau
plastique.This guard cable comprises a central reinforcing wire 1 around which are
arranged in
Les tubes câblés 2 sont disposés, soit parallèlement au fil de renfort central
1, soit enroulés en hélice autour de lui. The
Une armure est disposée autour du tube de maintien 4. Elle est ici composée de deux couches de fils 5, 6 jointifs dont les diamètres sont différents pour les deux couches.Armor is placed around the retaining tube 4. It is here composed of two layers of 5, 6 contiguous wires whose diameters are different for the two layers.
Selon l'invention au moins certains de ces fils d'armure sont réalisés en un
acier composite. Les fils réalisés en acier composite sont éventuellement intercalés
entre des fils en alliage d'aluminium. La couche extérieure d'armure peut aussi être
entièrement constituée en alliage d'aluminium. Chaque fil en acier composite
comporte un coeur 5A ou 6A en un acier, de type standard, qui est recouvert d'une
couche 5B ou 6B, en acier inoxydable. Il en est de même ici pour le fil de renfort
central 1 qui est constitué d'un coeur 1A recouvert d'une couche 1B.According to the invention at least some of these armor wires are produced in a
composite steel. The wires made of composite steel are optionally interposed
between aluminum alloy wires. The outer armor layer can also be
entirely made of aluminum alloy. Each composite steel wire
has a 5A or 6A core of steel, standard type, which is covered with a
L'acier composite mis en oeuvre est par exemple un acier fabriqué par la société STELAX sous la marque déposée NUOVINOX, il est obtenu à partir de tubes en acier inoxydable remplis de particules d'acier broyé qui sont comprimées sous forte pression dans les tubes. Les billettes obtenues à partir de ces tubes sont ensuite placées dans un four porté à une température de 1250°C, puis étirées sous forme de fils dont les sections respectives correspondent à celles souhaitées pour les fils de renfort et/ou d'armure.The composite steel used is for example a steel manufactured by the STELAX company under the registered trademark NUOVINOX, it is obtained from tubes made of stainless steel filled with crushed steel particles which are compressed under high pressure in the tubes. The billets obtained from these tubes are then placed in an oven brought to a temperature of 1250 ° C., then stretched in the form of wires whose respective sections correspond to those desired for the wires of reinforcement and / or armor.
Ceci permet d'obtenir des fils dont la périphérie présente une résistance à la corrosion qui correspond à celle d'un fil en acier inoxydable massif, pour un coût notablement moindre. La couche d'acier inoxydable du fil en acier composite correspond par exemple à une peau d'une épaisseur de 0,5 mm. Le coeur des fils en acier composite peut éventuellement présenter une résistance mécanique supérieure à celle de l'acier inoxydable, par exemple si ce coeur est constitué d'acier au carbone à haute résistance.This makes it possible to obtain wires whose periphery has resistance to corrosion which corresponds to that of a solid stainless steel wire, at a cost significantly less. The stainless steel layer of the composite steel wire corresponds for example to a skin with a thickness of 0.5 mm. The hearts of the sons in composite steel may have higher mechanical strength to that of stainless steel, for example if this core is made of carbon steel high resistance.
Dans l'exemple de câble présenté en liaison avec la figure 1, il est supposé
que le fil de renfort central 1 et les fils 5 et 6 des couches d'armure sont réalisés en
acier composite, pour bénéficier à la fois des avantages en matière de résistance
mécanique apporté par cet acier et de l'absence de dégagement d'hydrogène
souhaité en raison de la présence de fibres optiques dans le câble.In the example of cable presented in connection with FIG. 1, it is assumed
that the central reinforcing wire 1 and the
Bien entendu, il est possible de réaliser d'autres câbles de télécommunications où il est possible de tirer avantage de l'utilisation d'un acier composite pour des fils de renfort ou d'armure et en particulier des câbles de télécommunications comportant des fils ou des guides d'onde coaxiaux en matériau électriquement conducteur pour la transmission de signaux sous forme électrique.Of course, it is possible to make other cables of telecommunications where it is possible to take advantage of the use of a steel composite for reinforcing or armouring wires and in particular cables for telecommunications comprising coaxial wires or waveguides of material electrically conductive for the transmission of signals in electrical form.
La figure 2 présente un exemple de tronçon de câble de distribution
d'énergie armé qui comporte centralement trois conducteurs à torons multiples de
distribution d'énergie 7, par exemple en cuivre, chacun de ces conducteurs étant
revêtu d'une gaine isolante 8. L'ensemble est logé dans une gaine 9, formant
matelas, recouverte par un feuillard 10 éventuellement réalisé en acier composite,
tel que du NUOVINOX.Figure 2 shows an example of a distribution cable section
of armored energy which comprises centrally three conductors with multiple strands of
Le tube que forme le feuillard 10 est lui-même recouvert par une gaine
d'armure, ici à une seule couche, constituée de fils 11, disposés parallèlement ou
hélicoïdalement disposés autour de ce tube. Au moins certains des fils de l'armure
sont réalisés en acier composite et préférablement en NUOVINOX, à des fins de
renforcement mécanique, comme l'armure du câble de télécommunications présenté
sur la figure 1.The tube formed by the
