但是一些人却在质疑这个标准，因为从远距离传输来看，高压直流电缆损失的电量比交流电缆少。
Some people, however, question that standard because over long distances high - voltage DC lines suffer lower losses than AC.
这不仅能有利于电流的传送，而且通过使用高压直流电缆，人们可以对电网进行改造，从而更加有利于风能发电。
Not only does that make them better in their own right, but employing them would allow electricity grids to be restructured in ways that would make wind power more attractive.
由于在传输过程中采用高压直流电缆输送的损耗要比传统交流电的损耗小得多，因此采用交流电远距离传送电力很不划算。
Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic.
通过高压直流电电缆输电相同距离，损失只有2- 3%，这使得在最便宜的地方发电，再输电至最需要的地区去变得更易实现。
HVDC cables can transmit electricity over similar distances with losses as low as 2-3%, making it easier to generate electricity where it is cheapest and send it to where it is needed.
