HVDC is an ABB innovation that transports large power loads over long distances with low losses and minimal environmental impact, requiring just two 500 kilovolt (kV) DC power lines to carry the same power load as five alternating current (AC) lines.

• HVDC技术是ABB的一项创新，在长距离的传输中，它传送大量的电量，而损失很低，而且对环境的影响也达到最小化，只需要两条500千伏的直流电线就可以运载相当于五条交流电线输送的电量。
