SUBSURFACE ANODIC EARTH LEAD AND ACTIVATOR OF SUBSURFACE ANODIC EARTH LEAD Russian patent published in 2012 - IPC C23F13/16 

FIELD: electricity.

SUBSTANCE: subsurface anodic earth lead is made in the form of a garland of electrically and mechanically in-series connected separate anodic earth leads each of which includes central metal electrode on which metal elements are fixed; besides, it is enveloped with activator layer made in the form of cylinder coaxial to electrode and connected to previous and next electrodes into a common bar equal in strength throughout the length; at that, gaps between edges of cylinders of activator of neighbouring anodic earth leads are filled with activator up to surface of cylinders. Metal elements are fixed across the guide in the form of bars perpendicular to electrode; at that, each next element is perpendicular to the previous one along the axis in clockwise direction. Mixture of activator consists of oil calcined coke fines the fractions of particles of which are selected as to mass fraction and size, graphite and thermoplastic non-cancerogenic binding agent - bitumen waste.

EFFECT: use of subsurface anodic earth lead allows simplifying assembly and erection works, improving reliability and serviceability of anodic earth lead.
