Distributive cathodic protection devices are designed to protect against electrochemical corrosion of pipelines and other underground metal structures and have the possibility of automatic and manual regulation of the protective potential.
Low-voltage cathodic protection devices are designed to receive electrical energy of three-phase current with frequency of 50 Hz at rated voltage of 0,23 (0,4) kV and distribution in electrical networks with deaf-earthed neutral to cathodic protection converters and automatic reinforced drainage stations.
