Description

Technical Field

[0001] The invention relates to a special grounding wire clamp for a power transmission and distribution line, in particular to a special grounding wire clamp for a power transmission and distribution line which can be fully inserted or withdrawn quickly. Background Art

[0002] At present, the special grounding wire clamps used in power transmission and distribution lines are two types: double-spring special grounding wire clamps and spiral flat-end special grounding wire clamps. They do not have the function of quickly and fully inserting into the power transmission and distribution lines. In particular, when the special grounding wire clamps with spiral flat ends need to be installed upwards on the ground to the power transmission and distribution lines during field operations, it is often labor-consuming, time-consuming and laborious to hold the insulating rod with both hands and use a long time and physical strength to screw the spiral flat-end special grounding wire clamp onto the power transmission and distribution lines.
