Embodiment 1
[0023] Such as figure 1 As shown, the salt-corrosion-resistant torsion-resistant sub-shielded communication cable for marine wind power of the present invention includes the following steps in sequence: the outer periphery of the stranded copper conductor 1a is evenly extruded with a salt-corrosion-resistant and torsion-resistant rubber insulating layer 1b to form an insulated core 1, and the insulated wire The core 1 is twisted in pairs to form a pair of twisted wires. The gap between the pair of twisted wires is filled with a flame-retardant non-hygroscopic fiber core 2. Each pair of twisted wires adopts a different twisting pitch. Each pair of twisted wires The outer circumference of the pair is wrapped with copper foil polyester composite tape shielding layer 3 to form a twisted group; the copper foil of the copper foil polyester composite tape shielding layer 3 faces inward, and the inner side of the copper foil polyester composite tape shielding layer 3 is provided with a...
