Abstract
An electrical line for the connection of non-stationary electrical loads to a power source is specified which has a line core surrounded by a jacket (8) of insulating material. Four wires (1), stranded together to form one star quad (S), for the transmission of data, and also two wires (2) stranded together to form a pair of wires (A) and used for supplying power are placed in the line core. The star quad (S) and the pair of wires (A) are stranded together as stranding elements for forming the line core and, over the same, a layer (5) of insulating material is placed, over which a braid or a stranded cover layer of copper wires is arranged in a first layer (6) as part of an electrical screen. At least one layer of a fleece material consisting of synthetic material and made electrically conductive is placed over the first layer (6) as second layer (7) of the electrical screen and the fleece material is surrounded by the jacket (8) of insulating material.
