Under the trend of large-scale development of offshore wind farms in China, the installed capacity of individual wind farms continues to increase from 500 to 1,000 MW or even higher. However, the cost of using the sea is increasing correspondingly because of the scarcity of offshore wind farm resources. The traditional 220-kV three-core submarine cable can no longer satisfy the engineering requirements
