STEEL CORD COMPRISING LAYERS HAVING HIGH PENETRABILITY

摘要

The invention relates to a steel cord (30) comprising cylindrical layers, said cord including: an inner layer (C1) formed by M wires, an intermediate layer (C2) formed by N wires helically wound around the inner layer (C1), and an outer layer (C3) formed by P wires helically wound around the intermediate layer (C2), in which the inter-wire distance D2 of the wires of the intermediate layer (C2) is greater than or equal to 25 µm and the inter-wire distance D3 of the wires of the outer layer (C3) is greater than or equal to 25 µm.
