<p>The cable has four groups (P1-P4) wounded between them in order to form a helix of groups. Each group has two twisted conductive wires (FC11,FC12). Pitches (L1,L2,L3) of the helix of the groups varies along the cable between three limit values of same sign according to periodic function e.g. sinusoidal function. Independent claims are also included for the following: (1) a method of fabricating a helicoidal electric cable (2) a device for fabricating a helicoidal electric cable.</p> |
