Among them, 230KV aluminum core power cable refers to a power cable with a voltage of 230kV. In high-voltage cables, the conductors are divided to improve the cable's conductivity, heat dissipation and mechanical properties, thereby increasing the cable's service life.

[0003] A Chinese patent discloses an aluminum core split conductor insulated export power cable (authorization announcement number CN209747223U).

[0004] However, existing cables often utilize corrugated paper and elastic buffer structures for protection, which can easily deform and damage the cables when subjected to tension, shortening their service life. For example, the aforementioned reference document utilizes corrugated paper and other structures. In actual use, the cables are subject to significant tension, which can easily cause deformation and damage, impacting the cable's usability. Therefore, those skilled in the art have provided a 230kV aluminum core split conductor power cable to address the issues raised in the aforementioned background technology. Utility Model Content
