皮雷斯金、德列也夫、克拉尾克里斯合编物理课本第二卷第135节(1950年版)中叙述了远距离送电的问题。作为一个例子,教科书的作者提出了把电功率为33000千瓦的电能输送130千米远的问题。作者认为在110伏特输送这样大的电能时需要截面积为2400厘米~2、长260千米的铜导线,它的总重量为500000吨。用这个来说明在低压上远距离送电是不经济的。 Pireskin, Dellyf, Crater Chris, Compiling Physics Volume 2, Volume 135 (1950 Edition) describes the problem of long-distance power transmission. As an example, textbook authors have raised the issue of transporting 130,000 kilowatts of electrical energy 130 kilometers away. The authors consider a copper conductor of 2400 cm -2 and 260 km cross-sectional area at 110 volts to deliver such a large amount of electricity, with a total weight of 500,000 tons. Use this to demonstrate that it is uneconomical to deliver power over a low voltage over long distances.
