A low-capacitance, interference-free, stretch-prevention and high tensile strength digital audio video cable practical for a long-distance application is disclosed to include an electrical strand formed of multiple high-frequency transmission lines and low-frequency transmission wires and a filler, a tin foil layer surrounding the electrical strand, a braided layer surrounding the tin foil layer, and an outer plastic sheath surrounding the braided layer. Each high-frequency transmission line includes multiple high-frequency transmission wires that are equal in length and arranged in parallel, an insulation layer surrounding the high-frequency transmission wires, two shielding layers surrounding the insulation layer, and a grounding wire set in between the two shielding layers in a middle position relative to the high-frequency transmission wires.
