The invention provides a ten-strand all-steel cord of a (3+9)+8*(1+6)+1 structure. The ten-strand all-steel cord comprises a center core strand, eight outer-layer strands and an external winding wire, the eight outer-layer strands are evenly arranged around the center core strand to be knitted and twisted, and the external winding wire is wound around the outer-layer strands. The center core strand comprises three core steel wires and nine steel wires knitted and twisted around the three core steel wires in the same direction, and the outer-layer strands comprise a core steel wire and six steel wires knitted and twisted around the core steel wire; the eight outer-layer strands are evenly arranged around the center core strand to be knitted and twisted, and the external winding wire is wound around the outer-layer strands to form the ten-strand all-steel cord with a round section. According to the ten-strand all-steel cord, the diameter of the center core strand is larger than that of the outer-layer strands, the rubber seepage performance can be improved, binding force between the all-steel cord and rubber can be enhanced, and the corrosion resistance of tires can be improved. The eight outer-layer strands are adopted, and therefore the strength, rigidity and warping resisting performance of the all-steel core can be achieved.
