The invention provides a data transmission cable for a physically-foamed insulation transponder. The data transmission cable comprises a cable core, an insulating lining, a base sheath, an inner sheath, a double-steel belt armor layer and an outer sheath, wherein the cable core is stranded by two of four insulated single lines; the insulating lining, the base sheath, the inner sheath, the double-steel belt armor layer and the outer sheath are sequentially arranged outside the cable core from inside to outside; discharge copper leads are arranged between the insulating lining and the base sheath; and each insulated single line comprises a copper conductor and a skin-foam-skin physically-foamed insulation structure outside the copper conductor. The cable has the advantages of good moisture-proof function, excellent insulating property and small transmission attenuation. According to an aluminum sheath cable, a layer of inner sheath for longitudinally wrapping the outside of a corrugated single-side aluminum-plastic tape and a single-side aluminum-plastic tape is removed; by properly increasing the thickness of an aluminum layer of the aluminum sheath, the same shielding performance effect is reached; the manufacturing process is effectively reduced; the production efficiency is improved; and the manufacturing cost is reduced.
