The invention relates to a graphite-based flexible drag-reducing cloth for laying flexible graphite contact strip and a production method thereof, the graphite-based flexible drag-reducing cloth comprises a glass fiber grid and a graphite film covering the glass fiber grid, At that time of production, the expand graphite is expanded and prepress into a graphite film in turn, the glass fiber grid is impregnated with glue and compounded with a graphite film, dry bonding, then the expanded graphite worm is rolled and molded, 300mm wide, which combines the flexibility of the glass fiber grid withthe excellent corrosion resistance and electrical conductivity of the graphite film, The graphite-based flexible drag-reducing cloth is laid before and after laying the flexible graphite grounding material so as to avoid direct contact between the flexible graphite grounding material and the soil. By using the graphite-based flexible drag-reducing cloth in combination with the flexible graphite grounding material, better electric conduction and corrosion protection effects can be achieved.
