Automatic Enhanced Drainage Station with Digital Control Unit for Corrosion Protection

Stations of automatic reinforced drainage with digital control unit (SAUD-C), specialised for operation in systems of electrochemical protection of underground metal structures from corrosion caused by stray currents. The protection is provided by stray currents discharge from the underground metallic object through the station into the
negative busbar of tram or electrified railway traction substation, which are powerful sources of stray currents.
