Abstract
A method of manufacturing an electric cable includes winding together two groups in such a manner as to form a group helix, each group having two twisted-together conductor wires, and where the groups are wound together at a speed that varies between two limit speeds having the same sign and in such a manner that the pitch of the group helix varies along the cable between two limit values having the same sign.
Claims3
A method of manufacturing an electric cable said method comprising the steps of:
- winding together two groups in such a manner as to form a group helix, each group having two twisted-together conductor wires, and wherein the groups are wound together at a speed that varies between two limit speeds having the same sign and in such a manner that the pitch of the group helix varies along the cable in accordance with a periodic sinusoidal function between two limit values having the same sign.
