High-temperature-resistant flexible torsion-resistant cable for winding and production process thereof

The invention discloses a high-temperature-resistant flexible torsion-resistant cable for winding and a preparation method thereof, and relates to the field of locomotive cables for special smelting. When the flexible torsion-resistant cable for high-temperature-resistant winding is produced, the cable core is firstly prepared, then the cabling mylar tape is wrapped outside the cable core, then the lining layer is extruded outside the cabling mylar tape by adopting a semi-vulcanization extrusion process, then the reinforcing layer is woven outside the lining layer by adopting three strands of twisted 2500D aramid yarns per ingot, and finally, the cable core and the cabling mylar tape are subjected to extrusion molding to form the flexible torsion-resistant cable for high-temperature-resistant winding. And finally, extruding an outer sheath layer outside the reinforcing layer by adopting an extrusion type steam vulcanization process, wherein the inner lining layer, the reinforcing layer and the outer sheath la
