Function&Application Scenarios

In submarine cable systems, the constant DC line current is provided to submerged plants by power feeding equipment (PFE) located at the terminal stations. Ocean Ground Beds (OGBs) are the devices designed to make it possible to establish a power supply circuit between the PFE at each terminal station. The OGB can be connected with the PFE and carry the constant line current of the system, thus allowing the seawater to act as an electrode of the system's electrical circuit.
