Single-phase cross-linked insulating polyethylene cable of electrified railway with voltage of 27.5 kV

The utility model relates to a cable, in particular to a single-phase cross-linked insulating polyethylene cable of an electrified railway with voltage of 27.5 kV. The single-phase cross-linked insulating polyethylene cable of the electrified railway with voltage of 27.5 kV comprises a conductor, a conductor shield, an insulating layer and an insulating shield, wherein the conductor shield, the insulating layer and the insulating shield are sleeved outside the conductor, a copper wire shield is arranged outside the insulating shield, and an inner sheath and an outer sheath are arranged outside the copper wire shield respectively. The single-phase cross-linked insulating polyethylene cable of the electrified railway with voltage of 27.5 kV is characterized in that a semi-conductive cotton tape is arranged between the insulating shield and the copper wire shield, and an aluminum wire shield is arranged between the inner sheath and the outer sheath. The single-phase cross-linked insulating polyethylene cable of
