Abstract

La presente invención se refiere a un revestimiento para cables que es capaz de proteger al cable contra impactos accidentales. Al insertar en la estructura de un cable de transmisión de energía un revestimiento adecuado de material de polímero expandido, es posible obtener un cable que tiene una elevada resistencia al impacto. El Solicitante ha observado además que un material de polímero expandido utilizado como revestimiento para cables hace posible obtener una mayor resistencia al impacto par este cable que mediante el uso de un revestimiento similar con base en el mismo polímero que no se expande. Un cable con un revestimiento de de este tipo tiene varias ventajas sobre un cable convencional con una armadura exterior de metal, tal como, por ejemplo, un procesamiento más fácil, una reducción en el peso y las dimensiones del cable terminado y un impacto ambiental inferior con respecto al reciclaje del cable una vez que termina su ciclo de funcionamiento.The present invention relates to a cable sheath that is capable of protecting the cable from accidental impacts. By inserting into the structure of an energy transmission cable a suitable coating of expanded polymer material, it is possible to obtain a cable having a high impact resistance. The Applicant has further observed that an expanded polymer material used as a cable coating makes it possible to obtain greater impact resistance for this cable than by using a similar coating based on the same polymer that does not expand. A cable with a coating of this type has several advantages over a conventional cable with an outer metal reinforcement, such as, for example, easier processing, a reduction in the weight and dimensions of the finished cable and a lower environmental impact regarding the recycling of the cable once its operating cycle ends.
