Copper core cross linked polyethylene insulated steel wire armored water-blocking power cable

The invention discloses a copper core cross linked polyethylene insulated steel wire armored water-blocking power cable which comprises a cable core. The cable core is formed by stranding multiple wire cores. Water-blocking ropes are filled at gaps of cable cores, the cable cores are wrapped by a first water-blocking strip, an inner sheath is extruded outside the first water-blocking strip, the inner sheath is wound with a second water-blocking strip, the outside of the second water-blocking strip is woven with a steel wire armored layer, the steel wire armored layer is wound with a third water-blocking strip, and finally an outmost layer of the cable is extruded with an outer sheath. Each cable core comprises a copper conductor, the outside of the copper conductor firstly drags water-blocking yarns and then is wound with a semi-conductive water-blocking binding strip in an overlapped mode, the outside of the semi-conductive water-blocking binding strip is extruded with an inner shielding layer, an insulating
