The invention provides a high self-supporting and rapid heat radiating type shielding suspension wire data cable, comprising cable cores and protection sleeves disposed at the outer walls of the cablecores. Two groups of cable cores are arranged in parallel. Outer walls of the cable cores are respectively sleeved with an insulation sleeve. The outer wall of the insulation sleeve is sleeved with an aluminum ring circle, and the protection sleeve sleeves the outer wall of the aluminum ring circle. Cable compound is filled between the insulation sleeve and the aluminum ring circle. Zinc-coated wire embedded in the protection sleeve is disposed between the aluminum ring circle and the protection sleeve. The invention is advantageous in that the structure is simple and design is reasonable; byadopting multiple protection sleeves and the built-in zinc-coated wires, high self-supporting force of the cable can be realized; the internal stability of the cable during practical use can be ensured, and practical elastic-plastic performance of the cable can be maintained; the effect is obvious and the cable is convenient for popularizing and using.
