Description

Technical Field

[0001] The utility model relates to the technical field of electric power installation, in particular to a wire pulling hardware structure. Background Art

[0002] Wire tie fittings refer to fittings used to connect, fix, and adjust wires between pole towers and ground anchors. Wire tie material is galvanized steel stranded wire. Wire tie fittings are used to suspend, fix, protect, connect, and splice overhead lines or insulators on overhead transmission lines, as well as metal devices used to connect wires on the wire tie structure of wire tie towers. When pulling the power conductor, it needs to pass through the wire tie fittings and then continue to pull the power conductor to move, which will cause friction between the power conductor and the wire tie fittings. Although some existing wire tie fittings are equipped with rollers to reduce friction, due to the fixed angle of the rollers, this will cause the power conductor to fall off the rollers and cause friction when it needs to be pulled in other directions. Therefore, the existing roller structure needs to be improved. Utility Model Content
