Low-inductance flat cable

The utility model relates to a large-capacity storage and transmission cable. The technical problem to be solved is to provide a flat cable aiming at the defect that the prior cable is large in structural size so as to make a cable small in size and low in inductance in the using process. The low-inductance flat cable is characterized in that the conductor structure of the cable is composed of four flat copper foil layers including a flat copper foil layer I (2), a flat copper foil layer II (4), a flat copper foil layer III (6) and a flat copper foil layer IV (8) which are sequentially arranged in parallel, and two heads of the cable are provided with two conductor lead-out ends formed by through-hole split-level connection structures. According to the utility model, the principle of mutual inductance between differential modes is adopted, split-level connection of the flat conductor is used to reduce the inductance of the cable, a polyimide film with stable electrical performance is used as an insulation, the production technology of compression molding is used to produce the low-inductance flat cable, the cross section of the conductor of the cable can be increased, the requirement of the cable on high voltage can be met, and the cable can meet the use requirements of low inductance and high pulse current in a limited using space.
