【Abstract】 Graphite-based flexible grounding strip is a new type of non-metallic conductive material.The material itself has good conductivity,high and low temperature resistance,acid and alkali resistance,high inrush current resistance,and stable material properties.The use of graphite-based flexible grounding straps for transmission line grounding devices is a new development in the application of flexible graphite materials.Its main performance requirement is electrical conductivity.At present,China’s new type of graphite-based flexible grounding tape is woven from flexible graphite wire.Graphite wire is made by exfoliating graphite after high temperature expansion and rolling to obtain flexible graphite tape and then compounded with glass fiber through twisting.The electrical resistivity of the graphite strip directly affects the electrical properties of the new graphite-based flexible grounding strip.How to reduce the electrical resistivity of the graphite strip to improve the electrical performance of the new graphite-based flexible grounding body is the main objective of our research.更多还原
