Steel reinforced concrete electrodes for HVDC submarine cables

In the present paper, an innovative prototype of seawater anodes, based on steel reinforced concrete, is presented. Moreover, its experimental comparison in seawater at corrosive phenomena is reported, comprising simple steel or titanium bars and titanium meshes protected by special multi metal oxides (MMO). These experiments have shown important reduction of the corrosion phenomena in the case of the prototype of anode made by steel concrete.
