Embodiment 1
[0023] Such as figure 1 As shown, the salt-corrosion-resistant and torsion-resistant overall shielded communication cable for marine wind power of the present invention includes the following steps in turn: 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, and 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, and multiple pairs of twisted wires The cable core is formed by twisting, and then the outer periphery of the cable core is wrapped with a low-strength non-woven longitudinal cladding 3, and finally the inner sheath 4 is extruded on the outer periphery of the low-strength non-woven longitudinal cladding 3, and the inner sheath 4 will be low...
