Title:
DEEP-SEA FEEDER CABLE
Document Type and Number:
WIPO Patent Application WO/2018/223620
Kind Code:
A1
Abstract:
A deep-sea feeder cable, comprising an optical unit (2), an armor layer (3), a feeder layer (5), and an insulation layer (4). The armor layer (3) comprises an inner stranded layer and an outer stranded layer. The inner stranded layer has a plurality of first stranded metal wires (6). The outer stranded layer has a plurality of second stranded metal wires (8) and a plurality of third stranded metal wires (10). The second stranded metal wires (8) and the third stranded metal wires (10) are sequentially and alternately arranged, and the wire diameter of the third stranded metal wire (10) is less than the wire diameter of the second stranded metal wire (8). The plurality of first stranded metal wires (6) is stranded at an outer side of the optical unit (2). The second stranded metal wires (8) and the third stranded metal wires (10) are stranded at intervals along the first stranded metal wires (6). The third stranded metal wires (10) are stranded on the second stranded metal wires (8), wherein the stranding directions thereof are the same. The deep-sea feeder cable improves impact resistance, crush resistance, and the mechanical tensile properties of a deep-sea feeder sea cable, as well as the longitudinal water resistance and radial water resistance of the sea cable. This lowers manufacturing and maintenance costs of the sea cable, reduces damage to optical fibers during manufacture, and improves the insulative properties of the sea cable.
