1. Application
PC-1 B telecontrol and teletransmission cathodic protection system is suitable to protect all kinds of the metal-buried buildings, such as the pipelines, cables, piers, tanks, ships and coolers in the underground, sea, water or chemical medium by impressing current to offer cathodic protection. The system is provided with advanced technical index, high reliability and long service life.
PC-1 B is provided with interfaces to realize data telecontrol and teletransmission. The system includes two independent constant potential device and switch circuits for controlling operations of two constant potential device, can realize function of switching to constant current automatically when there are faults.
