Cables with various functions are used for cathodic corrosion protection.

Anode Cable
This cable connects the protective current device and the external current anode. The protective current device draws electrons from the external anode via the anode cable.
The anode cable is connected to the positive pole of the protective current device.
In a sacrificial anode system, the anode cable could be used to connect the anodes of an anode field to each other.

Protection cable, cathode cable
The electrical connection via the ProtectionCable actively feeds protective current into the system.
External anode protection system: The protection cable connects the protective current device to the pipe network. The cable is connected to the negative pole of the rectifier. The electrons flow from the external anode system (direct current source) via the cable to the pipe.
Sacrificial anode protection system: The electrons from the sacrificial anode circulate via the ProtectionCable to the pipe (cathode).
On the pipe surface, these electrons cause a chemical reduction reaction that binds the oxygen, thereby protecting the pipe.
The ProtectionCable can also be used to connect two separate pipes. For example, parallel pipes can be connected to the same cathodic protection system. The pipes are connected with the ProtectionCable and via the ProtectionCableConnectionPoint.

Measuring cable
Cables for measuring purposes. They connect the measuring device to the measuring point or test point in the network (reference electrode, anode, etc.).

Drainage cable
Drainage enables the controlled dissipation of harmful stray currents. Drainage is a cable connection (often with a diode or rectifier) between the protected object and an external stray current source (e.g. railway track) that conducts unwanted stray currents. Unwanted, corrosion-promoting stray currents are specifically drained via the drainage system and returned to the source so that they do not escape into the ground somewhere along the pipe and cause local corrosion.
