TWO-LAYER MULTI-STRAND CABLE HAVING A SHEATHED INNER LAYER AND AN IMPROVED PERFORMANCE

摘要

The invention relates to a two-layer multi-strand cable (50) comprising: - an inner layer (CI) that has two plies (C1, C3) and consists of K≥1 inner strand(s) (TI), and an outer layer (CE) consisting of L>1 outer strands (TE) that have two plies (C1', C3 ') and are wound around the inner layer (CI). The cable (50) is obtained by a method involving a step of manufacturing the sheathed inner layer (CIG) in which the inner layer (CI) is surrounded by an elastomer composition having a thickness G and then by the L outer strands to form the outer layer (CE), with L being strictly greater than Lmax, which is the maximum number of outer strands (TE) that can be arranged on the theoretical outer layer (CET) obtained when the inner layer (CI) is in direct contact with the theoretical outer layer (CET).
