Intelligent leakage current detection and interruption device for power cord

A power cord in a leakage current detection and interruption device, comprising:

• a first power supply line and a second power supply line;
• a first insulating layer and a second insulating layer, respectively covering the first and second power supply lines;
• a first leakage current detection line and a second leakage current detection line, disposed outside of the first and second insulating layers, configured to detect whether a leakage current is present on the first and/or the second power supply line;
• a first conductor wire and a second conductor wire;
• wherein each of the first and second power supply lines, the first and second insulating layers, the first and second leakage current detection lines, and the first and second conductor wires extends an entire length of the power cord between a line-side end and a load-side end of the power cord;
• and
• an insulating structure configured to electrically insulate the first and second leakage current detection lines and the first and second conductor wires from each other along substantially the entire length of the power cord;
• wherein the first and second leakage current detection lines and the first and second conductor wires are electrically connected in series to form a detection current path between a first point and a second point.
