Abstract: The present disclosure relates to a cold-resistant medium-voltage power cable, includes a cable body, wherein a bending protection sleeve is slidably sleeved over an outer end of the cable body. Through the cooperative use of the bending protection sleeve, the clamping disc, the flexible electric heating patch, and the bending sensing assembly, on one hand, the arrangement reduces the difficulty in bending the cable body during installation, prevents damage to the cable body caused by excessive bending, and improves the efficiency and safety of installing the cable body in cold regions; on the other hand, the arrangement enables heating treatment at a bent installation section of the cable body. This configuration not only enhances flexibility of the cable body during installation, reducing damage to internal conductive cores of the cable body, but also provides continuous thermal protection to the bent installation section during subsequent operation of the cable body.
