Abstract
The present invention relates to a helically-wound electric cable comprising at least two groups that are wound-together so as to form a group helix, each group comprising at least two twisted-together conductor wires. In the cable of the invention, the pitch of the group helix varies along the helically-wound electric cable between two limit values having the same sign.
Claims2
A helically-wound electric cable comprising:
- at least two groups of twisted pair conductor wires wound together so as to form a group helix, wherein said twisted pair components directly abut one another, wherein the pitch of the group helix varies along the helically-wound electric cable in accordance with a periodic sinusoidal function between two limit values having the same sign.
