INFLUENCE OF THE SPECIFIC ELECTRIC SOIL RESISTANCE ON THE SELECTION OF THE FORM OF CATHODE PROTECTION OF UNDERGROUND CONDUITS

Inthe articleis carriedoutthecomparativeanalysisofthecostof cathode protectionbythe superimposed current and the cathodic galvanic protection of underground metallic construction based on the example of conduits. Are revealed the economic advantages of protector protection, as the minimum with its use for the conduits with the contemporary qualitativeanticorrosiveisolation, which possesses high dielectric characteristics. The increased attention is given to the comparative estimate of the cost of the cathode protection of the unit of the length of underground conduit, which is determined with a change of the specific resistance of soil in the range from zero to hundred Om·m
