In response to the existing problem of single dimension of cable breakage detection index, a multidimensional non-destructive inspection of cable breakage is carried out using magnetic memory weak leakage detection technology. A parallel wire bundle consisting of 37 steel wires was used to simulate the cable specimen. The leakage magnetic signals of the radial wire breakage depth and the axis as well as the circumferential breakage width were measured and analyzed. The results show that the axial leakage signal BX can determine the location of radial wire breakage and its depth trend, and it can also qualitatively characterize the change of axial wire breakage width. The peak-to-valley value of the normal leakage signal BZ-L curve has a good linear relationship with the axial wire breakage width. The linear fit of each condition is higher than 0.984. Based on the peak and valley values of the BZ-L curve, a quantitative characterization of the axial wire breakage width can be achieved. A good correspondence also exists between the circumferential wire breakage width and the peak-to-valley value of the BZ-L curve. The simulation results match with the experimental analysis.
