FIELD: transportation, electricity.
SUBSTANCE: device comprises direct current source with the use of "sacrificial" electrode - metal with low electrochemical activity relative to iron, for instance magnesium. "Sacrificial" electrode is installed in the housing made of hollow cylinder provided at both butt ends with flanges and located on dielectric centralisers with holes. The device is accommodated in the most low part of pipeline.
EFFECT: protection efficiency enhancement.
