The invention discloses a cable for shallow sea wind power generation, which comprises a conductor, water-blocking tapes, an insulating layer and lining layers, wherein, the first water-blocking tape and the extruded insulating layer are wrapped sequentially outside the conductor to form insulating wire cores, and a plurality of insulating wire cores are twisted together to form a cable core; thefirst lining layer and the second water-blocking tape are wrapped sequentially outside the cable core; and the insulating layer and the first lining layer are formed by extruding a thermoplastic elastomer (TPE). In the invention, the insulating layer is made of a thermoplastic olefin (TPO) material in the TPE and the first lining layer is made of a thermoplastic starch (TPS) material in the TPE, wherein, the TPE has good electrical property, good mechanical property, excellent low-temperature bending property and excellent torsion resistance, high long-term working temperature up to 125 DEG C, better water resistance and excellent salt-fog resistance, and especially the TPE can still maintain good flexibility at -60 DEG C; and TPO has more excellent electrical property, and TPS has betterwater resistance than that of the TPO.
