Abstract

The invention relates to an electrode (1) for use as one pole when transmitting high voltage direct current in the ground and/or in water. The electrode (1) is arranged to be positioned in one borehole (10), and comprises a current lead-in means (2), and a structure (3) in conductive contact with the current lead-in (2), which structure (3) is provided with an active surface (3) of an electrochemically active coating (4). The structure (3) is preferably a pleated or corrugated structure, for achieving an enlarged active surface. The invention relates also to a process for the transmission of high voltage direct current by using a cable and a pair of electrode arrangements, whereby each arrangement consists of one or several electrodes, and whereby one electrode arrangement functions as anode and the other arrangement as cathode. The electrodes are submerged in their respective borehole, made at end points of a distance over which current is to be transmitted, down to a layer in the earth having good conductive properties, and leading the current in said layer and in the cable.
