High-flexibility fireproof cable and preparation method thereof

The invention provides a high-flexibility fireproof cable and a preparation method thereof.The high-flexibility fireproof cable comprises a wire core, an outer wrapping layer and a sheath layer, the wire core is formed by twisting a plurality of conductors, the periphery of each conductor is sequentially coated with an inner wrapping layer and an insulating layer from inside to outside, the outer wrapping layer is made of ceramic silicone rubber, and the insulating layer is made of silicon rubber. According to the high-flexibility fireproof cable provided by the invention, the material of the sheath layer is a thermoplastic elastomer, and after the layered structures are extruded at the periphery of the cable core, the flexibility and flame retardance of the cable can be improved at the same time, and the use requirements of the cable for the new energy automobile can be met, and the preparation method of the high-flexibility fireproof cable provided by the invention comprises the steps of conductor preparati
