Title:
DEFORMED WIRE FOR REINFORCING LAND OPTICAL FIBER CABLE
Document Type and Number:
WIPO Patent Application WO/2003/087418
Kind Code:
A1
Abstract:
A generally sectorial deformed wire for reinforcing a strong land optical fiber cable is produced from a wire for a long high-tensile steel wire excellent in cold workability. The deformed wire is characterized in that it contains 0.40 to 1.1 mass% of C, 0.15 to 1.5 mass% of Si, 0.20 to 1.5 mass% of Mn, and 0.0005 to 0.5 mass% in total of one or more of elements of Cr, Mo, V, Al, Ti, Nb, and B, the carbon equivalent Ceq=C+1/4Si+1/5Mn+4/13Cr satisfies the relations 0.80%≤Ceq≤1.80%, the deformed wire has a ferrite pearite structure or a pearite structure and a tensile strength of 1800 MPa or more, the cross section of the deformed wire is generally sectorial, such deformed wires are combined to form a cable having a circular hollow section and a hollow in which an optical fiber is accommodated.
