線。[Claims for Utility Model Registration] (1) On the outer peripheral surface of the insulating sheath 2 surrounding the conductor 1, there are at least unidirectionally wound protrusions 21 and 22 extending in the form of a unidirectional helical line having a pitch of an appropriate size. One protrusion 3 is provided integrally with the insulating sheath 2, and protrudes in the width direction of the protrusions 21, 22 at least once every 1/2 pitch between the protrusions 21, 22. An overhead insulated wire characterized by: (2) Extending in a helical line shape with a pitch of an appropriate size on the outer peripheral surface of the insulating sheath 2 surrounding the conductor 1,
At least one SZ winding protrusion 23 that changes the winding direction of the helical wire in the opposite direction with an appropriate number of pitches is integrally provided with the insulating sheath 2, and at least one SZ winding protrusion 23 is provided in the middle of the protrusion 23. An overhead insulated wire characterized in that a protrusion 3 protruding in the width direction of a protrusion 23 is provided at a ratio of one protrusion per half pitch.
