Abstract

A pumping installation for cooling one or more electric power cables with at least three different insulating oil channels, characterized by the fact that it comprises a circuit for cooling contemporary insulating oil in the cables and with separate phases, said circuit comprising at the opposite ends of the cables a multi-cylinder pump with volumetric cylinders with bellows in numbers at least equal to the channels, a pump drive mechanism common to all three cylinders and associated with a motor, an insulating oil tank and a solenoid valve near each end of each channel, each cylinder of the pump being connected with the suction to a tank and with the delivery to the end of a channel, each solenoid valve being inserted between the suction and delivery of each cylinder so to allow, when open, a flow of direct insulating oil between channel and tank and to allow, when When closed, the insulating oil is pumped from the reservoir to the channel.
