CABLE DE TRANSPORT D'ENERGIE ELECTRIQUE OU DE
TELECOMMUNICATION ET PROCEDE DE FABRICATION D'UN TEL
CABLE
La présente invention concerne un câble de transport d'énergie électrique ou de télécommunication comportant au moins un conducteur électrique central, une couche d'isolant coaxiale à ce conducteur et entourée d'un écran de protection et d'une gaine extérieure isolante.CABLE FOR TRANSPORTING ELECTRICAL ENERGY OR
TELECOMMUNICATION AND MANUFACTURING METHOD THEREOF
CABLE
The present invention relates to a cable for transporting electrical energy or telecommunications comprising at least one central electrical conductor, an insulating layer coaxial with this conductor and surrounded by a protective screen and an insulating outer sheath.
Elle concerne également un procédé de fabrication d'un tel câble.It also relates to a method of manufacturing such a cable.
Il existe actuellement une grande variété de câbles de transport d'énergie électrique ou de télécommunication comportant généralement un ou plusieurs conducteurs métalliques entourés d'une couche isolante, d'un écran conducteur et d'une gaine extérieure isolante.There is currently a wide variety of cables for transporting electrical energy or telecommunications generally comprising one or more metallic conductors surrounded by an insulating layer, a conductive screen and an insulating outer sheath.
Les conducteurs sont généralement du type multibrins en cuivre ou en alliages d'aluminium et l'écran est formé soit d'une tresse métallique soit d'un ruban métallique, d'une ou plusieurs couches de fils juxtaposés ou d'une gaine métallique extrudée. La couche isolante et la gaine extérieure isolante sont formées de polymères thermoplastiques ou réticulés. En outre, dans les câbles de transport d'énergie, étant donné que la périphérie du conducteur central n'est pas parfaitement circulaire, une première couche de semi-conducteur doit être interposée entre ce conducteur central et la couche d'isolant. Il en est de même entre l'isolant et l'écran. Enfin, les conducteurs sont réalisés de façon indépendante par exemple par tréfilage ou similaire et recouverts des polymères par extrusion sur une ligne de fabrication, ce qui nécessite des manipulations multiples et des équipements importants. Ce mode de réalisation présente différents inconvénients.The conductors are generally of the multi-strand type made of copper or aluminum alloys and the screen is formed either of a metallic braid or of a metallic ribbon, of one or more layers of juxtaposed wires or of an extruded metallic sheath. . The insulating layer and the insulating outer sheath are formed from thermoplastic or crosslinked polymers. In addition, in energy transport cables, since the periphery of the central conductor is not perfectly circular, a first layer of semiconductor must be interposed between this central conductor and the layer of insulation. It is the same between the insulation and the screen. Finally, the conductors are produced independently for example by drawing or the like and covered with polymers by extrusion on a production line, which requires multiple manipulations and significant equipment. This embodiment has various drawbacks.
Un conducteur métallique de grand diamètre est relativement lourd ce qui implique que le câble est également lourd. La manipulation d'un tel câble lors de sa production, de son transport ou de sa pose nécessite des équipements appropriés lourds et coûteux.A large diameter metallic conductor is relatively heavy, which means that the cable is also heavy. The handling of such a cable during its production, transport or installation requires appropriate heavy and expensive equipment.
L'écran de protection est difficile à mettre en place autour de la couche isolante et sa pose est parfois délicate, ce qui augmente de façon sensible le coût de fabrication du câble. De plus, dans les câbles de télécommunication, un écran de protection sous forme de tresse ne garantit pas une efficacité optimale pour assurer la protection contre les hautes fréquences.The protective screen is difficult to install around the insulating layer and its installation is sometimes delicate, which significantly increases the cost of manufacturing the cable. In addition, in telecommunication cables, a protective screen in the form of a braid does not guarantee optimum efficiency for ensuring protection against high frequencies.
Comme certaines parties du câble sont tréfilées et que d'autres sont extrudées, le câble ne peut pas être réalisé sur une seule ligne de fabrication. Les installations sont donc coûteuses et complexes.As certain parts of the cable are drawn and others are extruded, the cable cannot be produced on a single production line. The installations are therefore expensive and complex.
Les câbles comportant plusieurs brins conducteurs, ou un écran en forme de tresse, présentent des interstices dans lesquels l'eau peut s'infiltrer. L'étanchéification de tels câbles nécessite des composants additionnels et impose des interventions supplémentaires, ce qui renchérit le coût de production des câbles.Cables with several conductive strands, or a screen in the form of a braid, have gaps in which water can infiltrate. Sealing such cables requires additional components and requires additional intervention, which increases the cost of producing cables.
La présente invention se propose de pallier ces inconvénients en réalisant un câble particulièrement léger, qui peut être produit sur une seule ligne de fabrication, qui garantit une étanchéité transversale et longitudinale et dont l'écran de protection est particulièrement efficace contre les interférences électromagnétiques à haute fréquence.The present invention proposes to overcome these drawbacks by producing a particularly light cable, which can be produced on a single production line, which guarantees transverse and longitudinal sealing and whose protective screen is particularly effective against electromagnetic interference at high frequency.
Ce but est atteint par un câble tel que défini en préambule et caractérisé en ce que ledit conducteur électrique central et ledit écran de protection sont constitués d'au moins un - polymère intrinsèquement conducteur.This object is achieved by a cable as defined in the preamble and characterized in that said central electrical conductor and said protective screen consist of at least one - intrinsically conductive polymer.
Selon une forme de réalisation préférée, ledit polymère intrinsèquement conducteur est thermoplastique et comporte au moins l'un des composants suivants: polyacétate, polyacétylène, polyaniline, polyphénylène, polypyrrole, polythiophène, sulfure de paraphénylène.According to a preferred embodiment, said intrinsically conductive polymer is thermoplastic and comprises at least one of the following components: polyacetate, polyacetylene, polyaniline, polyphenylene, polypyrrole, polythiophene, paraphenylene sulfide.
Le but fixé est également atteint par un procédé de fabrication d'un câble de transport d'énergie électrique ou de télécommunication comportant au moins un conducteur électrique central, une couche d'isolant coaxiale à ce conducteur et entourée d'un écran de protection et d'une gaine extérieure isolante, caractérisé en ce que l'on réalise le conducteur électrique central et l'écran de protection en un polymère intrinsèquement conducteur.The aim is also achieved by a method of manufacturing an electrical energy transmission or telecommunication cable comprising at least one central electrical conductor, an insulating layer coaxial with this conductor and surrounded by a protective screen and an insulating outer sheath, characterized in that the central electrical conductor and the protective screen are made of an intrinsically conductive polymer.
On réalise avantageusement le conducteur électrique central et l'écran de protection par extrusion d'une matière synthétique thermoplastique comportant de préférence au moins l'un des composants suivants: polyacétate, polyacétylène, polyaniline, polyphénylène, polypyrrole, polythiophène, sulfure de paraphénylène.The central electrical conductor and the protective screen are advantageously produced by extrusion of a thermoplastic synthetic material preferably comprising at least one of the following components: polyacetate, polyacetylene, polyaniline, polyphenylene, polypyrrole, polythiophene, paraphenylene sulfide.
Selon un mode de réalisation préféré, on réalise le câble en extrudant simultanément ledit conducteur électrique central, ladite couche d'isolant, ledit écran de protection et ladite gaine extérieure isolante.According to a preferred embodiment, the cable is produced by simultaneously extruding said central electrical conductor, said insulating layer, said protective screen and said insulating outer sheath.
On réalise avantageusement l'écran de protection sous la forme d'un tube étanche.The protective screen is advantageously produced in the form of a sealed tube.
L'extrusion dudit conducteur électrique central et desdites couches successives superposées est de préférence effectuée au moyen d'une machine d'extrusion associée à des boudineuses dont le nombre est égal au nombre de matériaux différents à extruder pour constituer ledit câble, cette machine comportant au moins une tête d'extrusion à voies multiples, chaque voie étant connectée à une desdites boudineuses.The extrusion of said central electrical conductor and of said successive superposed layers is preferably carried out by means of an extrusion machine associated with extruders whose number is equal to the number of different materials to be extruded to form said cable, this machine comprising at minus a multi-channel extrusion head, each channel being connected to one of said extruders.
La présente invention et ses avantages apparaîtront mieux dans la description suivante d'un exemple de réalisation et en référence aux dessins annexés, dans lesquels: - la figure 1 est une vue en perspective d'un câble selon la présente invention; - la figure 2 est une représentation schématique d'une installation de fabrication du câble selon la présente invention; et - la figure 3 est une vue schématique d'une tête d'extrusion utilisée pour réaliser le câble de la figure 1.The present invention and its advantages will appear better in the following description of an exemplary embodiment and with reference to the appended drawings, in which: - Figure 1 is a perspective view of a cable according to the present invention; - Figure 2 is a schematic representation of a cable manufacturing installation according to the present invention; and - Figure 3 is a schematic view of an extrusion head used to make the cable of Figure 1.
En référence à la figure 1, le câble 10 comporte un conducteur électrique central 11 réalisé en un polymère intrinsèquement conducteur ayant un profil cylindrique de section circulaire. Ce polymère est avantageusement thermoplastique et comporte au moins l'un des composants suivants: polyacétate, polyacétylène, polyaniline, polyphénylène, polypyrrole, polythiophène, sulfure de paraphénylène ou tout autre composant similaire intrinsèquement conducteur. Le conducteur électrique central 11 est entouré d'une couche isolante 12 coaxiale à ce conducteur et réalisée en un polymère thermoplastique isolant tel que par exemple du chlorure de polyvinyle ou du polyéthylène. Un écran de protection 13 réalisé en un polymère intrinsèquement conducteur entoure la couche isolante 12. Cet écran forme un tube entièrement fermé autour de la couche isolante 12 et est également réalisé en un polymère intrinsèquement conducteur. Il est entouré d'une gaine extérieure 14 thermoplastique isolante en chlorure de polyvinyle ou en polyéthylène par exemple.Referring to Figure 1, the cable 10 comprises a central electrical conductor 11 made of an intrinsically conductive polymer having a cylindrical profile of circular section. This polymer is advantageously thermoplastic and comprises at least one of the following components: polyacetate, polyacetylene, polyaniline, polyphenylene, polypyrrole, polythiophene, paraphenylene sulfide or any other similar component intrinsically conductive. The central electrical conductor 11 is surrounded by an insulating layer 12 coaxial with this conductor and made of an insulating thermoplastic polymer such as, for example, polyvinyl chloride or polyethylene. A protective screen 13 made of an intrinsically conductive polymer surrounds the insulating layer 12. This screen forms a completely closed tube around the insulating layer 12 and is also made of an intrinsically conductive polymer. It is surrounded by an outer thermoplastic insulating sheath 14 made of polyvinyl chloride or polyethylene for example.
En référence aux figures 2 et 3, le câble selon la présente invention est obtenu comme suit.Referring to Figures 2 and 3, the cable according to the present invention is obtained as follows.
Une ligne de fabrication, représentée schématiquement par la figure 2, comporte une tête d'extrusion 15 illustrée en coupe de façon plus détaillée par la figure 3, pourvue de quatre entrées 16, 17, 18, 19 et de quatre sorties 20, 21, 22, 23 disposées à l'avant de la tête d'extrusion, lesdites entrées et sorties étant reliées respectivement entre elles. Les quatre entrées 16 à 19 sont respectivement reliées à quatre boudineuses 24, 25, 26, 27 contenant chacun une matière permettant de réaliser une couche du câble. La première sortie 20 est circulaire et permet l'extrusion du conducteur central 11 du câble.A production line, shown diagrammatically in FIG. 2, comprises an extrusion head 15 illustrated in section in more detail in FIG. 3, provided with four inlets 16, 17, 18, 19 and four outlets 20, 21, 22, 23 arranged at the front of the extrusion head, said inlets and outlets being connected respectively to each other. The four inputs 16 to 19 are respectively connected to four extruders 24, 25, 26, 27 each containing a material allowing a layer of the cable to be produced. The first outlet 20 is circular and allows the central conductor 11 to be extruded from the cable.
Les autres sorties ont une forme annulaire et sont disposées de façon concentrique autour de la sortie 20.The other outlets have an annular shape and are arranged concentrically around the outlet 20.
Le câble selon la présente invention est totalement réalisé par extrusion. Chaque couche recouvre entièrement la couche précédente.The cable according to the present invention is completely produced by extrusion. Each layer completely covers the previous layer.
Ce procédé permet une grande simplification de la fabrication puisqu'une seule ligne de production est suffisante. Il n'y a donc pas de manipulations intermédiaires pour la mise en place d'éléments métalliques comme cela est nécessaire sur les lignes classiques, ce qui entraîne un gain de temps ainsi qu'un abaissement substantiel des coûts de production. De cette façon, l'on améliore aussi considérablement la qualité et le facteur poids/puissance du câble.This process allows a great simplification of the manufacturing since a single production line is sufficient. There is therefore no intermediate manipulation for the installation of metallic elements as is necessary on conventional lines, which leads to a saving of time as well as a substantial reduction in production costs. In this way, the quality and the weight / power factor of the cable are also considerably improved.
Le câble selon la présente invention présente de nombreux avantages.The cable according to the present invention has many advantages.
Comme il n'est constitué que de matières thermoplastiques, il est entièrement recyclable. Il ne comporte pas de métal et est de ce fait particulièrement léger. A titre de comparaison, un câble à conducteur en cuivre de 1000 mm2 de section prévu pour une tension de 60 kV pèse environ 12,3 kg/m alors qu'un câble selon la présente invention pèse environ 3,1 kg/m pour les mêmes spécifications techniques.As it is made only of thermoplastic materials, it is fully recyclable. It does not contain metal and is therefore particularly light. By way of comparison, a copper conductor cable with a cross-section of 1000 mm2 intended for a voltage of 60 kV weighs approximately 12.3 kg / m while a cable according to the present invention weighs approximately 3.1 kg / m for the same technical specifications.
En raison de son mode de réalisation, l'étanchéité longitudinale du câble est garantie d'une manière absolue. De plus, comme l'écran de protection forme un tube fermé, cette protection est particulièrement efficace.Due to its embodiment, the longitudinal tightness of the cable is absolutely guaranteed. In addition, as the protective screen forms a closed tube, this protection is particularly effective.
La présente invention n'est pas limitée à l'exemple de réalisation décrit, mais s'étend à toute modification évidente pour l'homme de l'art. En particulier, les matières intrinsèquement conductrices peuvent être quelconques pour autant qu'elles atteignent les caractéristiques demandées. The present invention is not limited to the embodiment described, but extends to any modification obvious to a person skilled in the art. In particular, the intrinsically conductive materials can be any as long as they achieve the required characteristics.
