Claim:
A cable having a current leakage detection function, comprising: three current-carrying core wires, comprising a first current-carrying core wire connected to a live line of a power supply, a second current-carrying core wire connected to a neutral line of the power supply, and a third current-carrying core wire; three insulating films, comprising first, second and third insulating films, wrapping the first, second and third current-carrying core wires, respectively; a first current leakage detection layer wrapping an exterior surface of the first insulating film, and a second current leakage detection layer wrapping an exterior surface of the second insulating film, wherein each of the first current leakage detection layer and the second current leakage detection layer comprises a metal wire net and a single-sided conductive film laminated outside the metal wire net, and the single-sided conductive film comprises a dielectric insulating layer and a thin film conductive layer laminated on the metal wire net such that the thin film conductive layer is located between the metal wire net and the dielectric insulating layer, and each of the first and second insulating films wrapped by each of the first current leakage detection layer and the second current leakage detection layer is substantially in contact with the metal wire net and the thin film conductive layer, respectively, such that when a leakage current flows out of the first insulating film wrapped by the first current leakage detection layer from the first current-carrying core wire or flows out of the second insulating film wrapped by the second current leakage detection layer from the second current-carrying core wire, the leakage current flowing out is conducted to the corresponding metal wire net through the corresponding thin film conductive layer; an insulating shell wrapping the current-carrying core wires, the insulating films, the first current leakage detection layer and the second current leakage detection layer; and an insulating filler filled between the first current leakage detection layer, the second current leakage detection layer, the third insulating film not wrapped by the first current leakage detection layer or the second current leakage detection layer, and the insulating shell, such that the insulating filler is in contact with the dielectric insulating layer of the single-sided conductive film of each of the first current leakage detection layer and the second current leakage detection layer.
