Abstract
(EN)
A reinforced coaxial cable for underground service is disclosed. The cable generally comprises an elongate center conductor, a surrounding dielectric material such as a foamed polymer dielectric, an outer conductor, a first jacket, an intermediate protective layer, and a second jacket. A ripcord can be positioned longitudinally between the first jacket and the intermediate protective layer to facilitate removal of both the intermediate protective layer and the second jacket. A tracer, or other visible indicia, extends longitudinally along the outer surface of the second jacket to facilitate locating the underlying ripcord. The intermediate layer and the second jacket provide increased impact resistance, cut-through resistance, and compressive strength, as well as increased resistance to abrasion and other frictionally induced damage. In addition, the intermediate layer and second jacket can be readily removed to allow increased flexibility or connectorization of the cable.

L'invention concerne un câble coaxial renforcé pour des applications souterraines. Ce câble comprend généralement un conducteur central allongé, entouré d'un matériau diélectrique, tel qu'un diélectrique polymère en mousse, un conducteur extérieur, une première gaine, une couche de protection intermédiaire et une deuxième gaine. Un fil de séparation peut être positionné longitudinalement entre la première gaine et la couche de protection intermédiaire pour faciliter le retrait de la couche de protection intermédiaire et de la deuxième gaine. Un fil de repère, ou tout autre repère visible, s'étend dans le sens longitudinal le long de la surface extérieure de la deuxième gaine pour faciliter le positionnement du fil de séparation sous-jacent. La couche intermédiaire et la deuxième gaine confèrent une meilleure résistance aux chocs, ainsi qu'une résistance au perçage, à la compression et à l'abrasion supérieure et également une plus forte résistance aux endommagements produits par friction. En outre, la couche intermédiaire et la deuxième gaine peuvent être facilement retirées pour permettre une plus grande flexibilité et une meilleure possibilité de connexion du câble.
