Abstract

Installation for cooling electric power cables with at least three different channels for insulating oil, characterized by the fact of comprising: - at least one governing mechanism capable of creating pressure and suction in the insulating oil. - an insulating oil circuit comprising the said different channels hydraulically connected to each other by an end. - a control mechanism circuit capable of cyclically splicing the sending of the mechanism with the end of one channel and the aspiration with the end of the other channels arranged in parallel with each other, said extremities to which the mechanism is associated opposite to the hydraulically spliced together.
