Abstract
Electric interconnecting cables fitted with sealed electric connectors resistant to pressure are most often used to connect electrically together various equipments (1) distant from one another and immersed in a conducting liquid such as may be encountered in wellbores. To avoid this relatively costly solution, a process is proposed, wherein the various equipments (1) are linked together through sealed and empty hydraulic pipes or cables (22), so as to form a common space insulated from the external environment, and the electric linking conductors (25) are passed inside the hydraulic cable circuit constituted thereby.
