Auxiliary electrode is a steel electrode 6 with measuring cable 3 installed in the plastic body 5 and sealed with compound. Measuring cable 4 is equipped with cable tip 1 for connection to the control testing station or station of cathodic protection. Auxiliary electrodes are produced in the factory and delivered ready for installation.

There are 4 types of auxiliary electrodes depending on construction:
VE1250 – electrode square 1250 mm²;
VE625 – electrode square 625 mm²;
VE312 – electrode square 312 mm²;
VE156 – electrode square 156 mm².
