Zusammenfassung: | The utility model relates to a single-stranded compacted-strand reverse-lay steel wire rope which is used for oil pumping operation in an oil field and used as a substitute of a rigid sucker rod. The number of center steel wires, inner steel wires, sub-outer large steel wires, sub-outer small steel wires and outer steel wires is 35, wherein the arrangement mode of the center steel wires, the inner steel wires, the sub-outer large steel wires and the sub-outer small steel wires of an inner rope is 1-6-6+6, the 19 wires of the inner rope are formed by one-time laying and compaction on a stranding machine, and the lay pitch and lay direction of all layers are same; the structure of the compacted inner rope is indicated as K1*19W; an outer rope is formed by helically spinning 16 outer steel wires around the inner rope, and the lay direction thereof is reverse to that of the inner rope; and each layer is in compacted state, and adjacent layers and steel wires of each layer are in face contact.
