Definitions

  • the field of the invention is that of the design and manufacture of cables such as for example electrical or optical cables.
  • the invention relates to a cable comprising a protective sheath in which is housed at least one conductor and a method of manufacturing such a cable.
  • the invention has numerous applications in the field of cables, such as for example telecommunications, transport and distribution of energy.
  • an electric cable comprises a protective sheath in which is (are) housed one or more electrical conductors.
  • the purpose of this protective sheath is to insulate the electrical conductors from the external environment.
  • tracking systems such as for example marking by labeling, by writing area or by color code, have been devised to facilitate the tracking of cables. Most often, the cables are marked in relief or in ink on their outer sheath.
  • a known technique presented in the patent document GB 260,837 , consists in permanently fixing, on one or more arc portions of the external surface of the protective sheath of an electric cable, an indicator strip of colored plastic or polymeric material.
  • the color of the colored plastic or polymeric indicator strip is assigned according to the characteristics of the cable.
  • the IrisTech TM technique is also known, developed by the company Prysmian and described for example in the brochure entitled "Cabo Eprotenax Gsette® EPR 0.6 / 1kV".
  • This technique consists in producing, by extrusion-sheathing, a cable, the protective sheath of which comprises a longitudinal indicator strip, which constitutes a part of the surface of the sheath of the cable.
  • the tape is part of the protective sheath and is therefore not detachable, except using excessive force and except altering the circular section of the cable).
  • the strip is light in color and different from that (usually black) of the rest of the surface of the protective sheath.
  • the tape is such that a user can write on it (with a pencil of the type used to write on CDs) information useful for the installation or subsequent maintenance of the electrical assembly in which this cable is used. Thanks to a predetermined color code, the color of the strip indicates the electrical section of the cable (for example, a separate color for each possible section between 1.5 and 25 mm 2 ).
  • the indicator strip (colored strip) can be detached from the protective sheath.
  • the indicator strip is fixed to the protective sheath in a definitive and irremovable manner, so that removal of this indicator strip would cause deformation, or even tearing of the protective sheath, causing an irreversible deterioration of the protective sheath and, in particular, a change in diameter outside of the sheath.
  • the cable would therefore no longer have a circular cross-section and would most probably be out of standard.
  • the patent document JP 6 076646 describes a method of manufacturing a cable comprising a protective sheath in which a conductor is housed, and a plurality of indicator strips.
  • the indicator strips are glued to a part of the external surface of the protective sheath.
  • One or more indicator strips can be removed before the cable is stranded.
  • the patent document US 5,281,764 relates to a method of manufacturing a pair of color-coded stranded electrical wires for electrical cable. Each electric wire of the pair is extruded with a first insulating material, and a second insulating material, having a color different from that of the first material, is co-extruded on the first material.
  • the invention in at least one embodiment, aims in particular to overcome these various drawbacks of the state of the art.
  • an objective is to provide a technique making it possible to modify (change or delete) an initial identification of a cable, without causing deformation or alteration of the protective sheath of this cable.
  • Another objective of at least one embodiment of the invention is to provide a technique which can be applied to all types of cable, including those imposing a single sheath color.
  • At least one embodiment of the invention also aims to provide such a technique which makes it possible to maintain an outside diameter of the protective sheath within a standard value range, as well as a minimum thickness value of the protective sheath .
  • An additional objective of at least one embodiment of the invention is to provide such a technique which makes it possible to offer a surface finish of the tracking system suitable for writing.
  • Yet another objective of at least one embodiment of the invention is to provide a technique which relies solely on means conventionally used for cable manufacturing in an industrial environment, that is to say a technique which is simple to implement and inexpensive.
  • the general principle of a particular embodiment of the invention therefore consists in creating, on at least part of the external circumferential surface of a protective sheath of a cable, one or more indicator strip (s) removable (s), each having a level of adhesion to the protective sheath such that it can be detached from the protective sheath (manually for example) without altering the geometric structure of the latter.
  • the indicator strip (s) can be removed without tearing off the protective sheath (such tearing causes, in known solutions, an irreversible deterioration of the protective sheath and, in particular, a change of the outer diameter of the sheath).
  • the cable can therefore have a use other than that which was initially planned, the latter having retained its geometric and mechanical characteristics.
  • the indicator strip (s) being created on the one hand in excess thickness with respect to the protective sheath (in other words each indicator strip does not penetrate into the protective sheath) and on the other hand having a level of adhesion to the sheath protective allowing easy removal thereof, such removal therefore does not generate any defect or alteration of the outer circumferential surface of the protective sheath and the cable retains its usual circular appearance.
  • each indicator strip is very small and such that the presence of the indicator strip on the protective sheath does not generate protuberance. interference on the outer portion of the cable.
  • the invention in fact provides for compliance with the tolerance imposed on the outside diameter of the cable.
  • the invention also provides that the protective sheath has, when it is not covered with one or more indicator strips, a minimum thickness (generally imposed by a standard).
  • a minimum thickness generally imposed by a standard.
  • the present technique can be applied to all types of cable, including those imposing a single sheath color.
  • the indicator strip (s) of the invention are detachable and do not form part of the cable (unlike the indicator strips of the aforementioned known solutions). So, if a cable conforms to a standard imposing a single sheath color (for example entirely black sheath in the case of standard NF C 32-321), the presence of one or more detachable colored bands on the surface of this cable does not change the fact that the cable conforms to this standard.
  • the adhesion means of the removable indicator strip (s) on the protective sheath can be formed by adding an adhesive suitable for the above conditions to be met (level of adhesion to the protective sheath such that the strip can be detached from the protective sheath without altering it).
  • an adhesive suitable for the above conditions to be met level of adhesion to the protective sheath such that the strip can be detached from the protective sheath without altering it.
  • the predetermined threshold is between 0.1 and 10 N / mm, and preferably between 0.1 and 5N / mm.
  • Such a threshold allows sufficient adhesion of the indicator strip on the protective sheath while being able to be easily detached from the latter without changing its mechanical and geometric characteristics. Indeed, it is important to emphasize that, while being detachable when necessary, the indicator strip must remain firmly attached to the protective sheath during the storage, deployment and use of the cable (these operations involving mechanical and thermal constraints) .
