Abstract

The present invention relates to a ground electrode method for electrical protection of metal objects, which comprises the steps of: installing an electric corrosion ground electrode in an electrolyte medium at a planned distance from the metal objects to protect; electrically connecting the metal objects and the electric corrosion ground electrode to a power supply so as to form a protective circuit; and polarizing the metal objects. The method selects electrically connected parts and geometric size and/or electric variables of the ground electrode to obtain a current electric wave constant value of 10/m or lower in the protective circuit. The ground electrode comprises an envelope made of somewhat flexible current conductive materials based on a composition including: an extended center flexible metal conductor; an adhesive layer providing an electric contact; 40-80 wt% of a carbon-containing charging agent; 10-498 wt% of a rubber-basic copolymer; 9-10 wt% of a plasticizer; and 2-10 wt% of a pesticide.
