On top of that, the field generated by an alternating current interacts with the ground more strongly than it does with the air.
除此之外,在地下交流电相互影响产生的磁场比在空中强烈很多。
This creates losses 40 times higher in a buried cable than in an aerial one. Unless the long-distance-transmission system were converted to direct current, burial of transmission lines is not a serious option.
地底铺线比高空架线成本高了40倍。除非长距输电系统转换成直流电,地下输电才不至于是个笑话。
The second reason TenneTs pylons may be important is that despite these problems a lot of new long-distance-transmission lines are going to have to be constructed, soon. Wind power from the North Sea and the Atlantic Ocean will require that.
其次,不管这些,TenneT的电塔很重要是因为很快要修建不少新的长距输电线路,北海和大西洋的风力将会需要。
So, more speculatively, will the idea of generating solar power in north Africa and transmitting it to Europe.
所以理论上北非太阳能发的电传输到欧洲的想法越来越有可能。
In the Netherlands alone, TenneT says, more than 400km of new lines are needed.
TenneT表示,单是荷兰就需要400多千米的新电缆。
