Flexible fireproof cable

The invention provides a flexible fireproof cable. The flexible fireproof cable comprises cable cores, a thermal-collapse-resistant filling layer, a waterproof layer, an outer blocking layer and a sheath layer, wherein each cable core comprises a conductor, an inner blocking layer and an insulating layer from interior to exterior, at least one cable core is wrapped with the waterproof layer, the filling layer is arranged between the waterproof layer and the cable cores, the filling layer is formed by weaving ceramic silicon sealing strips and glass fiber in a winding mode, and the waterproof layer is wrapped with the outer blocking layer and the sheath layer in sequence. According to the flexible fireproof cable, on the premise that a high fireproof level is achieved, traditional technologies such as the wrapping technology and the cabling technology are adopted for all the important structures such as the inner blocking layers, the outer blocking layer and the thermal-collapse-resistant filling layer, and the problems that an existing fireproof cable is high in price, complicated in technology, large in manufacturing difficulty because special devices are needed, not convenient to construct because a metal sheath is hard and low in fireproof performance are effectively solved.
