Embodiment 1
[0019] Such as figure 1 As shown, the marine oil-resistant, paint-resistant and aging-resistant independent shielded power cable of the present invention includes the following steps in turn: uniformly extrude the insulating layer 1b on the outer periphery of the stranded copper conductor 1a, and wrap the inner wrapping tape around the outer periphery of the insulating layer 1b 1c, the outer circumference of the shielding inner wrapping tape 1c is covered with an independent shielding layer 1d, and the outer circumference of the independent shielding layer 1d is wrapped with a shielding outer wrapping tape 1e to form a power cable core, and the gap between multiple power cable cores After filling the flame-retardant polypropylene fiber core 2, it is integrally twisted to form a power cable core. The outer periphery of the power cable core is wrapped with a high thermal resistance coefficient flame-retardant fire-resistant longitudinal tape 3, and the high thermal resistance coe...
