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.
