A 66 kV torsion-resistant cable for wind turbine power transmission, and a preparation method. According to the 66 kV torsion-resistant cable for the wind turbine power transmission, the requirements of halogen-free, low smoke, aging resistance, special oil resistance, and a large torsion angle of a 66 kV wind-energy torsion-resistant flexible cable for a high-power wind turbine are satisfied by using a polyolefin rubber sheathing material and reasonably designing a cable structure, and the present invention has good practical value and popularization value; in the preparation method, a double-layer co-extrusion technology is used; a first sheath layer (8) and a second sheath layer (9) are tightly adhered together, and the protective effect is good.
