Natural Ventilated Single-Phase AC Rectifiers for Cathodic Protection (V-OPE)

Naturally ventilated single-phase alternating current rectifiers are designed for electrochemical (cathodic) protection of underground metal structures (gas pipelines, oil pipelines, public utilities and other facilities) from electrochemical corrosion, as well as for automatic reinforced drainage stations SAUD, specialised for operation in systems of electrochemical protection of underground metal structures from corrosion caused by stray currents
