Abstract
A reinforced coaxial cable for underground service is disclosed. The cable generally includes 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.
