Summary
As offshore wind power develops toward deeper waters, the installation costs of wind turbines continue to rise. To maintain cost-effectiveness, there is an urgent need to increase turbine capacity and improve cable transmission efficiency. A 110kV output voltage can eliminate the need for offshore booster platforms, thereby reducing the overall cost of offshore wind power. However, compared with existing 66kV cables, the 110kV high-voltage torsionresistant intelligent cable has a 20% larger outer diameter and more than 30% higher weight.

Experimental validation demonstrates that the developed cable exhibits exceptional performance: it withstands 10,000 torsion cycles at room temperature and 2,000 cycles at 40°C without failure; maintains 160kV/30min voltage withstand capability without breakdown; exhibits partial discharge (PD) ≤5pC at 96kV (1.5U₀); and achieves a thermal aging lifespan of ≥25 years.
