The invention discloses a cable used in a containment of a CAP1400 large pressurized water reactor nuclear power station. The cable comprises a conductor, an insulator, a lapping belt, an oxygen isolating layer, a shielding layer, an outer sheath and a polyimide belt, wherein after wrapping the conductor, the insulator is lapped by the lapping belt; the oxygen isolating layer wraps the lapping belt; the shielding layer wraps the oxygen isolating layer; the outer sheath wraps the shielding layer; the polyimide belt is lapped on the insulator; when the polyimide belt is lapped, each previous layer is partially covered by a part of the next layer. The cable used in the containment of the CAP1400 large pressurized water reactor nuclear power station is high in irradiation dose resistance.

The invention discloses a novel high-dose-irradiation-resistant cable structure used in a nuclear power plant containment vessel. The cable structure comprises conductors, insulators, a lapping belt, an oxygen isolation layer, a shielding layer and an outer protection cover. The insulators are wrapped in the lapping belt after wrapping the conductors. The oxygen isolation layer wraps the lapping belt. The shielding layer warps the oxygen isolation layer. The outer protection cover wraps the shielding layer. The cable structure further comprises polyimide belts which are wrapped on the insulators. When the polyimide belts are lapped, a part of the upper layer is covered with a part of the lower layer. The cable is used in the novel nuclear power plant containment vessel which is resistant to a large dose of irradiation.
