Description

Technical Field

[0001] The utility model relates to the field of electric power hardware, in particular to an insulating grounding wire clamp. Background Art

[0002] Insulated grounding wire clamps are generally installed and clamped on cables. They are devices commonly used in the maintenance process of high-voltage lines. Insulated grounding wire clamps mainly include a gland, a disk, and a grounding ring connected to the disk. The cable is clamped by the combination of the gland and the disk (usually bolts). Some types of insulated grounding wire clamps also include an insulating box. The insulating box wraps the gland and the disk as a whole to provide a certain insulation effect. However, a part of the existing grounding ring is exposed. For example, in a dry environment or a high-voltage environment, static electricity is easily generated, which poses certain installation risks to installers. Utility Model Content
