In order to enable the majority of cross-linked cable manufacturers and testing institutions at all levels to complete the mechanical performance tests, cross-linking degree, dumbbell pieces and other projects of cross-linked polyethylene cable insulation and sheath specified in GB/11017, GB/12706 and other national standards, our factory has developed the JQB-300 cross-linked cable slicer under the guidance of relevant experts from Shanghai Cable Research Institute, absorbing the advantages of similar foreign products. This function performs longitudinal cutting on cable samples to obtain high-quality sliced samples with different thicknesses of 0.10-1.5mm for different experiments, providing reliable data for the experiment. One test piece can obtain three dumbbell samples, with a sample uniformity of 0.05min
