摘要
PURPOSE: A mold for protective tube of an overhead earth wire is provided to prevent a breakaway of the protective tube of the overhead earth wire from a grip for the overhead earth wire by fitting the protective tube in the grip for the wire. CONSTITUTION: Both end point of a protective tube(50) of U section structure are compressed into the inner side by using a mold for protective tube. The protective tube of U section structure is shaped into the protective tube of "O" section structure. The molding toward both end point of the protective tube is carried out by using the mold for protective tube including the upper mold and low mold. An upper mold(70) is inserted in the bent portion of a grip(40) for an overhead earth wire. The upper mold has U shape. A U-shaped top groove is formed in the circumference of the upper mold. A U-shaped low groove(81) is formed in the low mold(80).
