A +/-800kV extra-high voltage direct current line cage type jumper wire structure is disclosed and is characterized in that one side of a soft jumper wire is connected with a strain wire clamp, the other side is fixed on a cage type hoop rack through a plurality of hoop type jumper wire spacing rods, the cage type hoop rack is connected to an iron tower through double V type jumper wire insulator chains, the cage type hoop rack and the V type jumper wire insulator chains are connected through hanging support racks, a plurality of six division jumper wire spacing rods are mounted on the soft jumper wire at each side, and six conducting wires are uniformly distributed at an interval. According to the +/-800kV extra-high voltage direct current line cage type jumper wire structure, one side of the soft jumper wire is connected with the strain wire clamp, the other side is fixed on the cage type hoop rack through the plurality of hoop type jumper wire spacing rods, the cage type hoop rack is connected to the iron tower through double V type jumper wire insulator chains, jumper wire offset can be reduced in sag and windage yaw time, the tower head size can be reduced, a pole tower can be lowered in height, steel materials can be saved and manufacture cost can be lowered. High mechanical strength is realized, a deflection-free property is basically achieved, a whole jumper wire system is free of field intensity concentration point, and the cage type jumper wire structure is good in electric corona condition and is convenient to install.
