Transformer rectifiers are AC (alternating current)-powered electrical equipment that provide DC (direct current) for impressed current cathodic protection systems. Transformer rectifier units are often custom manufactured and equipped with a variety of features, automatic output adjustment, various type of electrical enclosures, for operation in single or three phase AC input.
Our oil cooled cathodic protection rectifiers are industry leading in quality, workmanship and service life offering many years of trouble-free operation. Natural convectional oil flow is used to decrease the temperature gradient between outside ambient and transformer. Typically, Oil Cooled transformer rectifiers are generally used in severe weather conditions where Standard Air Cooled Rectifiers will not withstand adverse and harsh weather conditions.
