What Are the Advantages of DC Cables?

AC cable power transmission requires A.B.C three-phase cable, DC only requires positive. Negative two cables. Therefore, in the construction of cable lines that require high-cost construction, the cost of DC cables is nearly one-third less than that of AC cables.

AC cable power transmission relies on 50HZ sine wave induction to transmit power. The longer the line, the greater the load, and the more power loss in the line due to external induction, while DC basically has no such loss. See, DC saves 20% of line losses compared to AC.
