The invention discloses a durable cable, and belongs to the field of cables, and the durable cable comprises a cable core, a protection layer and an outer protection layer; the cable core is alternately and intermittently sleeved with small circular ring sleeves and large circular ring sleeves in the length direction of the cable core, and the opposite sides of every two adjacent small circular ring sleeves are located on the inner side of the large circular ring sleeve between the two small circular ring sleeves; a reinforcing core extending in the length direction of the cable is arranged at the circle center of the cable core, short supporting strips connected to the reinforcing core are fixed to the inner ring surface of the small circular ring sleeve at equal intervals along the circumferential side of the small circular ring sleeve, and long supporting strips connected to the reinforcing core are fixed to the inner ring surface of the large circular ring sleeve at equal intervals along the circumferential side of the large circular ring sleeve; an annular gap is formed between each small circular ring sleeve and the corresponding adjacent large circular ring sleeve, supporting blocks are distributed in the annular gaps at equal intervals along the circumferential sides of the annular gaps, and the supporting blocks are made of water swelling materials. The cable is firm in structure, reasonable in design, safe and reliable, has better compression resistance, tensile resistance, heat dissipation, waterproof performance and the like, and can improve the durability of the cable, thereby prolonging the service life of the cable.
