The invention discloses a steel wire rope, which comprises strands. The strands are in a group and encircle in a circle; the strands are tangent to one another; and the strands are made of steel wire groups and are non-circular. As the strands of the steel wire rope disclosed by the invention are non-circular and are pressed into a non-circular shape by using a special mold in a production process, no gap exists among peripheral steel wires of the strands, sewage can be prevented from entering the center of the steel wire rope in a working process, so that the center member of the steel wire rope can be prevented from getting rusty, and the rustproof performance of the steel wire rope is enhanced; meanwhile, the rotatability of the steel wire rope in the working process can be accordingly improved, thereby twisting is prevented.
