Bending-resistant power supply cable

The invention relates to the technical field of power lines, and provides a bending-resistant power cable which comprises a power transmission line and a signal transmission line, the power transmission line is provided with a plurality of first conductors and a plurality of first filling glass fiber ropes, the signal transmission line comprises a plurality of first conductors and a plurality of first filling glass fiber ropes, and the plurality of first conductors are stranded in a pitch layering manner. A signal line sheath is arranged on the periphery of the first conductor and the first filling glass fiber rope, and the signal line sheath is formed by weaving a plurality of strands of superconducting filaments; the power transmission line and the signal transmission lines are distributed in a circular shape as a whole, and a second filling glass fiber rope is arranged at the intersection point of the extension lines of the circle centers of the power transmission line and the signal transmission lines.
