Title (EN) CABLE WITH IMPACT-RESISTANT COATING
(FR) CABLE AVEC REVETEMENT RESISTANT AUX IMPACTS
Abstract:
(EN) The present invention relates to a coating for cables which is capable of protecting the cable against accidental impacts. By inserting into the structure of a power transmissioncable a suitable coating of expanded polymer material of adequate thickness, preferably in contact with the sheath of outer polymer coating, it is possible to obtain a cable which has a high impact strength. The Applicant has moreover observed that an expanded polymer material used as a coating for cables makes it possible to obtain a higher impact strength for this cable than using a similar coating based on the same polymer which is not expanded. A cable with a coating of this type has various advantages over a conventional cable with metal armor, such as, for example, easier processing, a reduction in the weight and dimensions of the finished cable and a lower environmental impact as regards recycling of the cable once its working cycle is over.
(FR) La présente invention concerne un revêtement qui permet de protéger les câbles contre les impacts accidentels. En effet, il est possible d'obtenir un câble présentant une forte résistance aux impacts. Dans ce but, on insère un revêtement approprié d'un matériau polymère d'une épaisseur adéquate dans la structure d'un câble de puissance, en le plaçant, de préférence, en contact avec la gaine du revêtement polymère extérieur. Par ailleurs, un matériau polymère expansé, utilisé comme revêtement pour câbles, permet d'obtenir une résistance aux impacts supérieure par rapport à un revêtement semblable en polymère non expansé. Un câble recouvert d'un revêtement de ce type présente divers avantages par rapport à un câble traditionnel avec une armature métallique, à savoir, un traitement plus facile, un moindre poids et des dimensions inférieures du câble fini, ainsi qu'un impact plus faible sur l'environnement, en ce qui concerne le recyclage du câble une fois son cycle de travail terminé.
