Description

Technical Field

[0001] The utility model relates to a grounding wire bending device, in particular to a portable grounding down conductor bending device, belonging to the technical field of electric power construction. Background Art

[0002] During the bending process of the grounding down conductor of the power transmission and transformation line project, the bending operation is mostly carried out manually. In order to meet the process requirements, the grounding down conductor needs to be connected to the grounding grid from top to bottom, close to the tower base, protective cap, and foundation column. During the bending operation, since the grounding wire is a relatively thick cable, it not only has a large radius but also has great toughness. The bending operation is time-consuming and labor-intensive, and the bending angle cannot be guaranteed, which seriously affects the construction progress and will also cause varying degrees of damage to the workers' hands.
