ANODIC GROUNDING CONDUCTOR (VERSIONS) Russian patent published in 2001 - IPC

FIELD: devices for cathodic protection of underground structures from corrosion, particularly, deep well grounding conductor; applicable in oil, gas and electric-power industries and in public utilities. SUBSTANCE: as compared with known multimode anodic grounding conductor containing electrodes with current leadouts electrically connected in parallel and located in series, novelty of claimed anodic grounding conductor consists in that its electrodes are connected with adapting members to form modules. The latter are combined in rigid column with autonomous leadouts through side surface of adapting members. As compared with known single-module anodic grounding conductor containing electrode with current leadout and contact unit, novelty consists in that it additionally has adapting member made in the form of two cylinders of different diameters conjugated between each other by truncated cone and by through hole passing from end of large-diameter cylinder to side surface of truncated cone. EFFECT: increased reliability and service life. 18 cl, 8 dwg
