Summary:PURPOSE:To effectively prevent the corrosion of a steel pipe buried under a power-transmission line for a long period by connecting galvanic anodes to the steel pipe and further connecting lower ground electrodes to the steel pipe through reactance circuit elements so as to prevent the AC corrosion of the galvanic anodes. CONSTITUTION:Galvanic anodes 4a, 4b for electrolytic protection are connected to a steel pipe 2 buried under a power-transmission line 1. Lower ground electrodes 3a, 3b made of an electrically conductive material other than the material of the anodes 4a, 4b are further connected to the steel pipe 2 through reactance circuit elements including at least capacity reactance circuit elements 7a, 7b.
