Abstract

A transposed cable (1) is disclosed comprising a core (2) consisting of a plurality of flattened wires (3) disposed in mutually superposed relationship to form two stacks (4a, 4b) arranged parallelly and side by side, the flattened wires (3) located at the base and on top of said stacks (4a, 4b) being cyclically transposed from one stack to the other. One or more thread-like elements (6a, 6b) of polyester or any other appropriate material are helically wound around the core (2), optionally in opposite winding directions. At least one ribbon-like element (7) of paper or other material is wound over the thread-like elements (6a, 6b) and superposed thereon, said ribbon-like element being tearable by means of a tear thread (8) longitudinally interposed between the paper ribbon (7) and the thread-like elements (6a, 6b) wound over the core (2). The tear thread (8) is used to remove the paper ribbon (7) when the cable (1) is wound around a winding core (23) to make an electric winding. <IMAGE>
