FIELD: railway and industrial transport and underground transport.
SUBSTANCE: proposed dc traction power supply system includes traction substations and contact systems of several parallel tracks supplied by said substations with sectionalizing boxes approximately in middle of inter-substation zones, or without such sectionalizing boxes. Power supply of running trains is provided mainly by superconducting cable line laid parallel to contact system of each track or both tracks and connected by wires of contact system in several points over their length.
EFFECT: reduced power losses in traction system, increased traffic capacity and distance between traction substations.
