The invention discloses a cold-resisting torsion-resisting wind power generation medium voltage cable and a production process thereof. The production process comprises the following steps: 1, a torsion-resisting conductor which meets an American standard is made; 2, a steam crosslinked composite insulation shielding group grows outside the conductor via a rubber CCV catenary; 3, a torsion-resisting and flame retardancy-resisting metal shielding group is made outside the crosslinked composite insulation shielding group; and 4, an oil-resisting, low temperature torsion-resisting and high-flame retardancy outer protection layer is made outside the metal shielding group. The cold-resisting torsion-resisting wind power generation medium voltage cable made by the method of the invention has the characteristics of oil resistance, moisture resistance, -40-DEG C low temperature torsion resistance, and UL/CSA double authentication, the medium voltage cable of the invention can be connected with an electric cabinet in seaside and inland cable towers requiring UL/CSA authentication in foreign countries such as the America and North America, a cable with a corresponding structure can be made according to a different environment, and power transmission requirements can be met.
