Abstract: An electrical connection line (L) for an electrical unit of a motor vehicle, which electrical connection line serves to electrically connect the unit to an electrical power source which is arranged in the motor vehicle and/or to another electrical unit. The connection line (L) is designed as a three-phase line with three insulated electrical conductors (1, 2, 3), of which each has an electrical individual sheath (5) which is in contact with its insulation means (4) and is closed all the way around. An electrical outer sheath (7) which surrounds the three sheathed conductors (1, 2, 3) and is closed all the way around is also provided and a coupling element which is equipped with electrical contacts which are insulated from one another is fitted at least to one end of the connection line (L) in a moisture-tight manner, and the electrical conductors (1, 2, 3), their individual sheaths (5) and the outer sheath (7) are electrically conductively connected to the contacts of the said coupling element.

Abstract: A flat conductor ribbon cable (1) in which at least two flat electric conductors (2) with rectangular cross-section are embedded, separated and in parallel, in insulating material (3). For effective electric shielding, a metallic envelope (4), which is produced by application of a process for surface coating and is completely closed, is applied to the entire outer surface of the flat cable (1) including the lateral edges (6,7) and adheres firmly to the insulating material (3) of the flat cable (1).

Abstract: An optical waveguide, in particular for a vehicle, with an optical fiber (1) which is composed of polymer material and with a protective layer which encloses the fiber (1). The waveguide includes a metal pipe (2) having a corrugation at an angle to its longitudinal axis (4), the pipe forming an electrical conductor, and being externally insulated (5).
