Abstract: This paper introduces a newly developed anti-drop grounding wire for multi-split conductors, which is mainly composed of a grounding end clamp, a grounding wire, an insulated wire, and a key conductor end clamp. The materials selected for each component are reasonable, and they have good mechanical properties, as well as conductive and insulating properties. The operation process is clear and convenient. When hanging, it is fixed and locked by tension;when removing, the spring releases force. This device adopts a double-conductor hook and a cassette spring for cooperation, which is stable in fastening and efficient in hanging; it can adjust parameters to meet the needs of various split conductors and have strong generalization; most of the main parts are standard, with low processing costs, which is conducive to mass production.
