Beschreibung
Zusammenfassung:	The invention relates to an overhauling tool used for a +/-660kV direct-current transmission line, comprising fixtures and a tensioner, wherein the fixtures are clamped on two sides of an insulator, and the tensioner is connected between the fixtures. Each fixture comprises an upper V-string clamp, an upper cross arm clamp, a single-string fixture, a big knife clamp, a closed clamp and a conductor end fixture and is made of a TC4 titanium alloy. The overhauling tool has the advantages of reasonable structure, high overall intensity and bearing capacity, small volume, light weight and the like, is reliable to work, is applied for overhauling the 660kV direct-current transmission line and provides reliable guarantee for the daily overhauling after the line is safely put into operation and operated.
