Answer: Direct Current (DC) cables are highly advantageous for long-distance power transmission, especially for projects like HVDC (High-Voltage Direct Current) submarine interconnectors. The primary benefit is significantly lower transmission losses, which is critical over vast distances. DC cables also don't experience the same charging currents as AC cables, allowing for longer cable lengths without intermediate compensation stations. This makes them more efficient and cost-effective for transmitting large amounts of power over long distances, particularly in subsea or underground applications.
