▎ 摘　　要

NOVELTY - The wire (2) has an insulating protective layer (1) and core wires. A detection wire body is electrically connected with an additional signal wire (3). The core wire includes a conductor group (4) and an insulating layer (5) wrapped around the outer periphery of the conductor group. The detection and additional signal wires and a number of the core wires are all wrapped around an insulation within the protective layer. The wires are copper wires, enameled copper wires or nickel-clad copper wires. A shielding signal layer is a synthetic graphene layer. A radial cross-section of the wires is circular. USE - Automatic leakage detection wire for performing signal transmission or power supply. ADVANTAGE - The leakage between the detection line and the additional signal line is caused. The external signal detection device can detect it in time, and the staff can repair in time if the connection is disconnected. The damage to the internal structure of the cable is easily detected, resulting in the failure to repair the cable in time which is likely to cause damage to electrical facilities. The leakage detection wire has high durability and is less affected by external influences, the cables will inevitably be damaged, broken, and broken during long-term use. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an automatic leakage detection wire. 1Insulating protective layer 2Automatic leakage detection wire 3Additional signal wire 4Conductor group 5Insulating layer
