The utility model discloses a low temperature-resisting highly-flexible transparent TPU ship power cable comprising a conductor and an insulation layer. The insulation layer is wrapped around the conductor in an extruded manner; the conductor is a category-6 anaerobic copper wire stranded conductor. The conductor comprises a plurality of stranded wires which are twisted for multiple times. Central stranded wires and outer-layer stranded wires are twisted in the left direction. Each stranded wire is formed by bundling a plurality of category-6 single copper wires in the left direction. The insulation layer is formed by extruding transparent TPU. The low temperature-resisting highly-flexible transparent TPU ship power cable is simple and reasonable in structure; the low temperature resistance of the cable is excellent; the low temperature tensile elongation of the insulation material at the temperature of minus 65 DEG C reaches a value greater than 50%; the cable is of great flexibility and can bear 60000 single-pass flexing tests (30000 double-pass flexing tests); and the cable is good in transparency and physical and mechanical performance.
