Background
In the field of electric lightning grounding, steel and copper metal materials and coating alloy materials such as galvanized steel and copper-coated steel are generally adopted as grounding materials of electric grounding nets. Since metallic materials are subject to corrosion problems that are difficult to avoid during operation for decades or even decades. The graphite cable grounding material is a novel grounding material which has been developed in recent years, effectively solves the corrosion problem of metal grounding materials, and is widely applied to the field of electric lightning protection grounding. Different from conventional welding connection modes such as electric welding, gas welding and exothermic welding of metal grounding materials, the main components of the graphite cable grounding material are graphite, inorganic fibers and synthetic fibers, and the non-metallic materials cannot be connected by the conventional welding mode. Operation experience shows that the grounding grid formed by the graphite cables has stable electrical, mechanical, anti-corrosion and anti-aging properties, and the mechanical property of each grounding body connecting node of the grounding grid is usually weaker, which is directly related to the service life of the grounding grid. Therefore, the reliable grounding device designed for the graphite cable grounding material has important significance for maintaining the service life of the whole grounding grid.
