Прочитайте текст и определите, какой из заголовков соответствует тексту.
A superconductive electric cable was made by the research workers at the Power-Engineering Institute. It is a very useful device and its main property is its being cryogenic. Compared with other types of cables, it has a great advantage – its use will result in transmitting current practically without losses, which is of great importance since nowadays percentage of losses in transmitting electric power over long distances is rather high; it is ten per cent and even more.
The properties of the new cable being unique, electric current up to 10,000 amp at 10,000 V and more can be transmitted over long distances. The superconductive cryogenic transmission lines are especially efficient for Russia: the power resources of the country are known to be concentrated mainly in the eastern parts of the country while three-quarters of the industrial potential are concentrated in the European part.
