AC-current diverter

direct product selection

Active (cathodic) corrosion protection means that the equipment to be protected is secured durably by active interference into the electrochemical process of corrosion. A power rectifier is inserted between the equipment to be protected, such as a pipe line, and an anode which serves as grounding unit.

Gas Discharge Tube (GDT)

direct product selection

Atmospheric discharges, inductive interferences, frictional electricity or direct contact with high-voltage conductors can provoke short-term voltage surges which are coupled into telecommunications lines or any kind of process measuring and control lines and which, as a result, disturb or destroy the electric or electronic installations connected to them.
