The invention discloses a photoelectric composite torsion-resistant medium-voltage wind power cable and a preparation method thereof, comprising a cable core, a cable-forming tape layer, an inner sheath layer, an aramid braided layer and an outer sheath layer, and the outer sheath layer of the cable core is sequentially Coated into a cable wrapping layer, an inner sheath layer, an aramid fiber braiding layer and an outer sheath layer; the cable core is composed of three power transmission cores, three ground cores and an optical fiber unit twisted. The present invention introduces an optical fiber structure into the cable, which can be better used for signal transmission, and through its own system line resources, has the characteristics and functions of the optical cable, realizes system operation monitoring, and ensures safe and stable operation of the system. Both the power transmission core and the ground core are made of aramid braided reinforcing layer. The continuous use temperature range of aramid fiber is ‑196°C to 204°C, and its strength is high, which is 5 to 6 times that of steel wire. The torsion causes the core to be damaged and cracked, so as to ensure that the cable will not be cracked or damaged during torsion, so as to prolong the service life of the cable.
