The invention relates to a soft ceramics insulation high-temperature fire-resistant cable which is specially used in a fire-fighting system and high-temperature workplace. A soft ceramics insulation material is coated on a cable conductor. The cable is soft between minus 40 DEG C and 200 DEG C, and can become a hard ceramics material when baked under a flame over 500 DEG C. 20% -22% of organic silica 704, 1%-2% of DCBPO, and 14%-16% of sintering additive Y203 are firstly added into 65%-60% of zirconia and then coated on the cable conductor after being processed by a stirring mill and an internal mixer; under room temperature, the zirconia particles and sintering additives are adhered together by the vulcanized organic silicon adhesive. The product has high production efficiency and fast production speed which can be 80 meters per minute and is dozens times of an ordinary mica tape fire-resistant cable. The invention has good fire-resistant property and can become a ceramics shape whenbaked under a flame over 500 DEG C; under the condition of fixing pavement, the normal working environment temperature can reach 850 DEG C. The invention has good softness and the same softness between minus 40 DEG C and 200 DEG C with a polymer material cable.
