Two-layer multi-strand cable with improved performance sheathed inner layer

摘要

The invention relates to a two-layer multi-strand cable (50), comprising: - an internal layer (CI) with two layers (C1, C3) consisting of K≥1 internal strand (s) (TI) and an outer layer (CE) consisting of L> 1 outer strands (TE) with two layers (C1 ', C3') wound around the inner layer (CI). The cable (50) is obtained by a process comprising a step of manufacture of the sheathed internal layer (CIG) in which the internal layer (CI) is surrounded with an elastomeric composition having a thickness G then L external strands to form the external layer (CE), with L being strictly greater than Lmax which is the maximum number of outer strands (TE) that can be placed on the theoretical outer layer (CET) obtained when the inner layer (CI) is directly in contact with the theoretical outer layer (CET).
