ANODE EARTH Russian patent published in 1994 - IPC

FIELD: electrochemical protection of metal using activities against corrosion. SUBSTANCE: the input earth uses main conductor, single-core or multi-core one, and electrode of little soluble polymeric material made in the form of a multi-layer flexible sheath embracing the conductor and having an electric contact with it. The sheath is made in the form of alternating current-conducting and electric insulating sections that are connected in a monolith by means of dielectric bushes. The sections and bushes are made of different elastomers featuring a thermodynamic property. Each conductor core has assigned electric characteristics (for instance due to variable section of the core). The sheath on the whole is made with discretely variable electric characteristics determined from relations. EFFECT: facilitated procedure. 3 cl, 3 dwg
