Rectifier Transformers

Cathodic Protection Transformer Rectifier

A rectifier transformer is a product used in applied current cathodic protection (ICCP) systems and its function is to convert single-phase or three-phase AC current into a designed DC current. This company produces various types of rectifier transformers required by the industry as follows: Cooling: Oil and air-cooled Control system: electronic, regulative, electronic-regulative and 63-step

SKU: CP-TR-240 Made to Order

transformer rectifier cathodic protection ICCP oil immersed CP rectifier pipeline tank piles

The rectifier transformer is the direct current power supply for applied current cathodic protection (ICCP) systems for pipelines, tanks and other metal structures buried or immersed in oil, gas and petrochemicals. This device is produced in two types: oil-cooled and air-cooled. In the oil-cooled type, the transformer and rectifier assembly are located inside the oil chamber, and the oil is responsible for cooling and insulation. The output voltage and current can be adjusted depending on the project needs through an electronic, reguvolt, electronic-reguvolt or 63-step control system. The device is manufactured with appropriate electrical protections, such as protection against overcurrent, short circuit and overtemperature, for continuous operation in industrial environments.
