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 invention discloses an aramid fiber armoring manufacturing process for an anti-slip photoelectric composite cable. Comprising the following steps of paying off of a photoelectric composite cable core, first constant tension traction, coating of a water-based adhesive, armoring of a first layer of aramid fiber, armoring of a second layer of aramid fiber, armoring of a third layer of aramid fiber, armoring of a fourth layer of aramid fiber, drying, extrusion molding, second constant tension traction and finished product take-up. By means of the mode, the manufacturing process of the anti-sliding photoelectric composite cable aramid fiber armor achieves production of the low-gap-ratio, high-strength and anti-sliding underwater special photoelectric composite cable aramid fiber armor, solves the problem of sliding between the aramid fiber armor layer of the photoelectric composite cable and the inner and outer protective layers, and improves the anti-sliding performance of the photoelectric ...
