Embodiment 1
[0023] Such as figure 1 As shown, the salt-corrosion-resistant torsion-resistant power cable for marine wind power of the present invention includes the following steps in turn: uniformly extruding a salt-corrosion-resistant torsion-resistant rubber insulating layer 1b on the outer periphery of the stranded copper conductor 1a to form a power cable insulating core 1, A plurality of power cable insulated wire cores 1 are twisted together to form a power cable core, and the outer periphery of the power cable core is longitudinally wrapped with a low-strength non-woven fabric longitudinal cladding 2, and the outer periphery of the low-strength non-woven fabric longitudinal cladding 2 is extruded The sheath 3 tightly squeezes the longitudinal sheath 2 of the low-strength non-woven fabric on the insulated core of the power cable. The thickness of the low-strength non-woven longitudinal cladding 2 is 0.05 mm, and the longitudinal cladding is sequentially overlapped along the axis of...
