Ground anode prepacked with backfill in a flexible structure for cathode protection with impressed currents

摘要

Flexible ground anode prepacked with backfill for protection of a cathode with impressed currents, made up by a flexible anodic conductor (1), surrounded by backfill and coaxially centered as to the flexible external casing (2) by means of spacers (3), which function also as current distributors to the casing itself, and supporting the anodic elements (4). The flexible casing (2) and elements (3) are constituted by metallic materials corrodable by the current.
