Abstract

A cooling tube (T) is incorporated into each conductor (C1) of the coil. The current carried by this conductor is divided between the strands which are maintained in thermal contact with the tube even in transposition or twist areas in which the conductor undergoes particularly marked deformations. The conductor features at least one half-turn twist between the electrical terminals of the coil.
