The diameter of strand becomes smaller, the surface of strand becomes smooth, and the contact surface between wires increases after die drawing, rolling or forging. The steel wires in the strand contact each other with spiral surface, which is formed on the basis of online contact structure, so it has higher breaking force. The contact area between the compacted strand wire rope and the pulley or drum is large, which makes the compacted strand wire rope more wear-resistant and corrosion-resistant. Especially when the wire rope is used on the multi-layer coiling drum, the smooth surface of the compacted strand wire rope ensures that the adjacent ropes will not be scratched or damaged due to mutual friction.
