Popis:	Design versions of HTS cables with the screened phases ensuring the AC losses minimization have been investigated by the numerical simulation methods. The following methods of optimization have been proposed: sectioning of phases, using of HTS tapes with the modified configuration and variation of the phase diameter. At the critical current of a phase of 5.1 kA and its rated current of 4 kA, these methods allow lowering of AC losses level to 0.45 – 0.017 W/m what is much lower than natural heat fluxes into a cryostat. The designs proposed are compared with ones of the optimized tri-axial cables what allows a reasonable choosing of a cable type vs. a given electric power system design.
