A circuit board assembly has a circuit board and a high-speed cable. The high-speed cable has two signal lines, a ground conductor, an impedance-reducing conductor, and a covering material. The signal lines, the ground conductor, and the impedance-reducing conductor are mounted through the entire high-speed cable. The covering material wraps the signal lines, the ground conductor, and the impedance-reducing conductor, and has a conductive layer and an isolation layer as an inner layer and an outer layer respectively. The conductive layer has multiple loops electrically connected to the ground conductor and the impedance-reducing conductor. Thus, the impedance in the covering material, the ground conductor, and the impedance-reducing conductor is decreased, which prevents from attenuating the signal intensity during transmission at high frequency.

A twinaxial parallel cable includes two conductors arranged parallel to each other, an insulating layer formed around the two conductors by extrusion coating, a shield tape wound around the insulating layer while extending longitudinally, a drain wire arranged inside the shield tape, and an outer coating formed to cover the shield tape. A cross section of the insulating layer perpendicular to a longitudinal direction of the twinaxial parallel cable is formed into an oval shape having a long axis that is 1.7 to 2.2 times a length of a short axis. The insulating layer has a groove in a portion including an intersection of an outline of the insulating layer and a perpendicular bisector of the long axis. The groove is formed to be more than 0.5 times to 0.9 times an outer diameter or a thickness of the drain wire. The drain wire is retained in the groove so that a part of the drain wire protrudes toward the shield tape beyond the insulating layer.

A method for producing a self-closing foil sheathing (14) wound onto at least one line (10) of a cable arrangement (12) includes providing an elastically deformable foil strip (16) which, in a load-free or bare state, is bent in a plane of the foil strip (16). The foil strip (16) is wound onto the line (10) in order to form the foil sheathing (14) which surrounds the line (10). The foil strip (16) during winding onto the line (10) is elastically deformed radially to the outside and in this way is subjected to radial loading in the direction of the line (10).
