Zusammenfassung:The invention discloses a bending-resistant low-temperature-resistant cable for a well drilling device, and relates to the technical field of cables, an outer sheath is made of a TPEE elastomer, an inner sheath is made of a TPE-EP6000 series elastomer, and insulation is TPV insulation at the temperature of-60-125 DEG C, so that the cable has high strength, low temperature resistance and good flexibility at the same time; the reinforcing part is formed by weaving aramid fibers, and the aramid fibers are soft in texture, small in density, high in strength and high in modulus, so that the mechanical performance of the cable is further enhanced, and the mechanical performance of the cable is further enhanced by utilizing the technology of bunch stranding and compound stranding of multiple strands of fine conductors, the technologies of arranging aramid yarns in the wires, controlling wire core grouping stranding, cabling small pitch control, homodromous stranding of all working procedures and the like. And the be
