Description

The ElectroTechCP? durAnode4 vertical is the result of constant development of cathodic protection and is designed to be mounted in the soffit of structures and contains some unique features. All exposed parts are made of titanium to ensure high durability and can be completely hidden. It can also be used in historic buildings to protect steel girders and places where weight and dimension of structures are important, such as car parks or other types of bridges. It may also be used for hot spot protection which can reduce the costs without reducing the protection levels. It consists of a titanium anode head and an active anode of MMO coated titanium.

Important Features of the Anode Head

? By using a built-in resistor, an adjustable and optimal current output and distribution can be established.

? This resistor, combined with a relatively small sized an-ode area, prevents major differences in current output, and allows a higher average current density than for a system with large anodes and no pre-resistor.

? The pre-resistor prevents short circuit of all anodes on a string in case of one single short circuit, and offsets the output in concrete at varying conductivity and this reduces the number of zones.

? Several durAnodes may be connected on a single feeder wire reducing the installation work by using a screw of Titanium that penetrates the insulation and makes a connection to the feeder wire. This means that the wire should not be stripped but just placed in the anode head.
