由此可见，下一代电线会比现在多传输四分之一的电流，而且不需要添加任何大容量的绝缘材料。
That means the next generation of power lines could carry up to a quarter more current without adding any more bulky insulation.
只使用具备适当容量的高级绝缘电线。尺寸过小的电线会造成电阻和随之的电压降落。
Use only high grade insulated wiring of suitable capacity. Undersized wires will cause resistance and consequent voltage drop.
800千伏特高压直流变压器是实现远距离、大容量输电的特高压输电线路的关键设备。
The 800 kV UHVDC transformer is a key component of ultrahigh-voltage power links that deliver large amounts of electricity over very long distances.
