Granular superconductor considered as a multiple Josephson medium, for modeling the electrodynamics of which the averaged material equation has being proposed. Evaluations of the critical parameters of the medium (the magnetic field penetration depth and the first critical field) are been obtained. The simulation of the current flowing through the granular superconductor wires was conducted. The presence of the skin effect in such wires at lowest frequencies down to DC is shown. The recommendations are made to use the stranded wires for the transmission of high currents.
