This air-cooled transformer rectifier is a kind of automatic controlled transformer, used as the DC power for impressed current cathodic protection. With the advantages of compact structure and light weight, it is ideal for smaller installations in cleaner environments. Typically, it is widely used for the cathodic protection of long pipelines, tank interior bottom, buried or submerged steel structure, etc.
