PROBLEM TO BE SOLVED: To provide a manufacturing method of a snow resistant twisted wire conductor that a snow resistant ring can be bonded strongly to the twisted wire conductor and a resin overflow part causing corona discharge in use can be removed easily.SOLUTION: A manufacturing method of a snow resistant twisted wire conductor forming a snow resistant ring together by molding thermosetting resin on the surface of the twisted wire conductor comprises: a step forming thermosetting resin in a ring shape with a die on the surface of the twisted wire conductor, and re-heating the ring part consecutively after the die is opened; and a step removing an overflow part on the ring part after the re-heating.SELECTED DRAWING: Figure 4 |
