The future power grid will be developed in the direction of large capacity, long distance, high economic efficiency, high reliability, and low environmental impact, while the development of distributed energy, offshore wind power delivery, and development of island resources will also rely on DC cables for power transmission. Therefore, the r...
The system used is different. The DC cable is used in the rectified DC transmission system, and the AC cable is often used in the power frequency (domestic 50 Hz) power system.
