They are commonly used in urban underground power grids, power plant lead-out lines, power supply inside industrial and mining enterprises, and underwater transmission lines.

[0003] Cables are electrical devices used for power transmission, signal transmission, or data communication. However, most cables have low torsional resistance, making the internal cores prone to twisting and breaking during installation, thus reducing the cable's performance and lifespan. Furthermore, cables have insufficient compressive strength, making them susceptible to internal damage from compression or crushing, which also reduces their transmission efficiency. Utility Model Content

Moreover, the compressive strength of the cable is not perfect, and the cable is easily damaged when squeezed or crushed, which reduces the cable's transmission performance.
