Enhanced Diode-Resistor Block for Corrosion Protection (BDRM) - Safeguard Underground Metal Structures

Modernised diode resistor blocks (MDB) are designed for simultaneous protection of up to 4 unconnected underground metal structures from corrosion, eliminating the harmful effect of electrochemical protection installations on adjacent utilities. BDRM works together with rectifier or protectors, providing protection of structures by setting the rated value of protection current for each of the objects depending on the state of their insulation.
