The invention discloses a sealing and anti-
corrosion protection method of a suspension bridge cable 
system, and belongs to an anti-
corrosion protection method of a bridge cable. The method helps divide the whole cable 
system into 7 types of surfaces: an outer surface of a main cable of a wire wrapping section; the outer surface of the main cable of a non-wire wrapping section; the outer surface of a main cable 
saddle exposing a strand; the outer surfaces of a cable strand inside an anchor chamber, a sling 
wire rope, as well as a railing 
rope and a side 
rope of a maintaining roadway; the outer surfaces of a cable clamp, a cable 
saddle (sleeve) and a 
saddle, and exposed surfaces of bolts and nuts; the outer surfaces of an anchor cup, a sling clamp, a sling 
shock mount, and columns and brackets of the maintaining roadway; and gap sealing surfaces of the cable clamp, a cable jacket girth seam, an abutted seam and a top saddle opening. The 7 types of the surfaces are treated by different methods, and the sealing and anti-
corrosion method is complete. In the method, novel sealing materials and anti-corrosion paints are used, which has good sealing performance, long anti-corrosion service life and high strength, and ensures the durability of the suspension bridge cable 
system.
