。[Scope of Claim for Utility Model Registration] (1) The outermost layer strands 1 consist of a large number of thin aluminum segment wires 2 each having a substantially truncated sector-shaped cross section, and one or several thick-walled aluminum segments having a substantially truncated sector-shaped cross section. A spiral protrusion 5 made of the protruding portion 4 of the thick aluminum segment wire 3 is formed on the outer periphery of the outermost layer strand 1, and the thick aluminum segment wire 3 is twisted in a mixed manner with the segment wire 3. An overhead bare electric wire characterized in that a magnetic metal wire 6 that exhibits ferromagnetism only at a temperature below the allowable heat generation temperature of the bare electric wire is embedded inside the strand 3. (2) The outermost layer strand 1 is a mixed strand of a large number of thin aluminum segment wires 2 having a substantially truncated fan-shaped cross section and one or several thick aluminum segment wires 3 having a substantially truncated fan-shaped cross section. A spiral protrusion 5 made of a protruding portion 4 of a thick aluminum segment wire 3 is formed on the outer periphery of the outermost layer stranded wire 1, and a bare electric wire is formed inside the thin aluminum segment wire 2. An overhead bare electric wire characterized in that a magnetic metal wire 6 that exhibits ferromagnetism only at a temperature below the allowable heat generation temperature is embedded therein. (3) The outermost layer strand 1 is a mixed strand of a large number of thin aluminum segment wires 2 having a substantially truncated fan-shaped cross section and one or several thick aluminum segment wires 3 having a substantially truncated fan-shaped cross section. A spiral protrusion 5 made of the protruding portion 4 of the thick aluminum segment wire 3 is formed on the outer periphery of the outermost layer stranded wire 1, and the thin aluminum segment wire 2 and the thick aluminum segment wire 3 are connected to each other. Inside the wire 3, there is a magnetic metal wire 6 that exhibits ferromagnetism only at a temperature below the allowable heat generation temperature of the bare wire.
An overhead bare electric wire characterized by embedded.
