Cable extracted from a single layer with a uniform distribution of metallic wire elements

Abstract

The invention relates to a cable extracted (50) from a polymer matrix, the extracted cable (50) comprising a single layer (52) made up of N metallic wire elements (54) wound in a helical fashion, each metallic wire element (54) of the layer (52) describing, when the cable (50) extends in a substantially rectilinear direction, a helical trajectory around a principal axis (A) substantially parallel to the substantially rectilinear direction, with the space between two adjacent metallic wire elements being defined by: δ = (Dh-Df x sin(atan(cos(α) x tan(θ/2)))) x sin(θ/2) – Df x cos(atan(cos(α) x tan(θ/2)))x cos(θ/2)/cos(α), α being the helix angle, expressed in radians, of each metallic wire element (54) and θ being The angle, expressed in radians, between the minor axes of two successive ellipses representing two adjacent metallic wire elements (54) in the cross-section of the cable (50). The ratio δmax / δref ranges from 1.0 to 2.9, where δref is the case where the spacing between the N metallic wire elements is the same and δmax is the case where the spacing between two adjacent metallic wire elements is greater than δref.
