The circular strand structure of steel wire rope is simple and stable, with a light weight and uniform curvature radius of the steel wire. It has good flexibility, strong bending resistance, and is not easy to cause stress concentration. It can be made into both co directional and interactive twisting structures. Its interactive twisting structure not only reduces the torsion of the wire rope itself, but also greatly reduces the elongation of the wire rope itself.

圆股结构的钢丝绳结构简单而稳定，单重轻，钢丝曲率半径-致，柔韧性好，抗弯曲能力强，不容易造成应力集中，既可以制成同向捻，也可以制成交互捻结构。其交互捻结构不仅降低了钢丝绳自身扭力，也大大降低了钢丝绳自身伸长量。

The triangular strand structure of steel wire rope has a larger metal cross-sectional area, higher breaking force, and greater safety factor. Single weight, stronger resistance to compression and wear. However, the characteristic of being able to only produce with the same direction twisting structure determines that the torque is greater and is not suitable for deep well lifting.
