This paper presents an analytical estimate of various self-field losses in the superconducting MgB2 cables recently proposed for long-distance (3000 km) dc power transmission. We show the advantages of dc transmission with respect to ac taking into account hysteresis loss estimation, and we optimize the design of MgB2 cables accordingly.
