摘要： A power cord includes an outer coating layer. Live, neutral, and ground wires are in the outer coating layer. The live wire includes a core and first insulation layer. Live wire shielding and second insulation layers are successively sheathed outside the core. The neutral wire includes a core and first insulation layer. Neutral wire shielding and second insulation layers are successively outside the neutral wire core. The ground wire includes a core and insulation layer sheathed outside the ground wire core. When the live and neutral wire shielding layers are broken or the live wire and its shielding layer are short-circuited, and the neutral wire and its shielding layer are short-circuited, the leakage protector detects an abnormal signal of the power cord and interrupts the electrical connection of the live and neutral wires, to prevent fire between the live and neutral wire cores after the power cord is broken.

摘要： Provided is a power cable and a method for manufacturing a power cable that reduces occurrence of uneven thickness of an insulating layer and voids and peeling due to shrinkage and has good dielectric breakdown strength. The power cable includes the insulating layer containing 15 mass % or more of a propylene-based resin having a melting point of 110° C. or higher with respect to a whole. The power cable further includes a relationship between a cooling rate X [° C./min] at the time of manufacturing an interface portion in the insulating layer with the inner semiconductive layer and a cooling rate Y [° C./min] at the time of manufacturing a central portion of the insulating layer and is expressed by the relationship (Z), wherein X≥Y×0.8 . . . (Z).

摘要： The present invention discloses a shielding layer detection circuit and a transmission system. The shielding layer detection circuit includes a first resistive voltage division assembly, a second resistive voltage division assembly, a switch module, and a control module. The first resistive voltage division assembly is connected to a conductive shielding layer group to detect an electric leakage signal; the second resistive voltage division assembly has a first detection terminal connected to one terminal of the conductive shielding layer group and a second detection terminal connected to the other terminal of the conductive shielding layer group to detect a breakage signal; the switch module is connected to a power supply bus bar group to switch a transmission line connection/disconnection state of the power supply bus bar group.
