Summary:The invention relates to a device for testing cable core tension, in particular to a fireproof cable core tension test device. The invention aims to provide the tensile test device for the cable core of the fireproof cable, which can stop the movement of the cable core after the cable core is snapped, ensures the detection result, and is simple in structure and low in failure rate. The fireproof cable core tension test device comprises a workbench, a hydraulic cylinder and a tension meter, the hydraulic cylinder is installed on one side of the top of the workbench, and a piston rod of the hydraulic cylinder is connected with the tension meter. During operation, circuit supply can be carried out through the cable core, and when the cable core is snapped, circuit connection can be stopped, so that the electromagnet and the hydraulic cylinder stop running, the situation that the clamp continues to drive the cable core to move, and detection of the stretchable length of the cable core is affected is avoided, and
