Abstract. The current distributions within a power transmission cable composed of helically wound long tape superconductors have been studied by solving the circuit equation with the inductance matrix among divided segments within a tape conductor under the Bean model. The self- and mutual inductances of helical thin tape conductors are calculated from the analytical expressions in the form of an infinite series. In addition, it is shown that the distinction between the right-handed and left-handed helixes is generally necessary in the mutual inductance between two long coaxial helical conductors.
