▎ 摘　　要

NOVELTY - The device has a ground wire (102) used to form an annular ground wire through a composite wire clamp. A composite leading-out wire (101) is connected with the annular ground wire through the composite wire clamp. A composite grounding rod (104) is connected with the annular ground wire through the composite wire clamp. A bottom of the composite grounding rod is detachably connected with an alloy tip. The composite leading-out wire is connected with a rod tower leg through a wire clamp of a starting end. USE - Complete set of a grounding device in a narrow area. ADVANTAGE - The device is light weight, convenient carrying, low transportation cost, reducing the excavation area of the narrow area, reducing grounding net construction amount, and mostly covered by multilayer composite graphene stable material performance, low resistivity, high resistance, low temperature, acid resistance, alkali corrosion, anti-impact current, stable material property, improving the service life of the grounding device, with high economic popularization value. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the complete set of a grounding device in a narrow area.
