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.
High-voltage cathodic protection devices are designed to receive energy of three-phase current with frequency of 50 Hz at rated voltage of 6 (10) kV, convert it to rated voltage of 0,23 (0,4) kV and distribute it in electrical networks with blind-earthed neutral to cathodic protection converters and automatic reinforced drainage stations.
