Title: CONCRETE COVER FRAMES FOR ANODE NETS
Abstract:
A cover frame (2) for an electrode (1) for a device for transmitting heavy current over a sea, said device comprising a first conductor in the form of a cable, which is adapted to be placed on the bottom of the sea and to be connected to/integrated with a land-based connnection cable, and a second conductor, which consists of the sea water and which by means of said electrode immersed in the sea is connected to a land-based connection cable. The cover frame is adapted to be placed on the bottom of the sea (3) over the electrode (1) and comprises at least two opposite side walls (6) which are essentially parallel with the longitudinal axis (15) of the cover frame, and a roof (5). Moreover, the cover frame (2) is formed with a plurality of through openings (7) in the side walls (6) and in the roof (5), and the electrode (1) is supported by the cover frame (2) at a distance from the bottom of the sea (3).
