Torsion makes the conductor in the cable prone to breakage, and wind energy cables in some special areas require good flexibility, torsion resistance, vibration resistance, and good flame retardancy, while existing wind energy cables cannot meet these requirements. As a result, the existing wind energy cables generally have a short service life, which not only increases the cost input, but also brings great potential safety hazards.
