In order to improve the adaptability of grounding wire in the complicate environment of field production and optimize the safety performance of grounding wire

a new tongue-type compaction style grounding wire clamper is designed. The clamper adds an anti-drop device based on the existing tongue-type compaction style grounding wire clamp. The practice proves that it can prevent the grounding wire from falling off from the clamper. It enhances the safety performance of the grounding wire and has good application value and popularization significance.
