Translated by Valentina Sukhanova from Russian

  At power stations electric power from the electric generators is transferred to transformative substations and further to electric power lines by armoured cables. Cable - Transformer can do work of those cables and substations, at that its cover from transformative steel does work of an armour and the cable wires do work of transformative windings.

  Example 1 Three-phase dividing Cable - Transformer.

  Section of such Cable - Transformer is shown on Fig. 2

  In suggested transformer the steel armour 7 does work as a magnetic conductor and protective cover. The transformer has relatively larger surface, what allows it to have effective cooling, which is reached not due to a special cooling system, but due to the originality construction of the Cable - Transformer.

  Example 2. One-phase step up (step down) Cable - Transformer is shown on Fig. 3 and its section - on Fig. 4.
