Chemical Cell

Application

Transformation of chemical energy of active substances it contains into electric power by way of electrochemical reactions, with following purposes:

• — maintenance of protective potential at the metal structure (pipe) in order to prevent corrosion;
• — feeding other articles in the combined corrosion protection and telemechanics circuit.

The structure is installed in soil with conductor outlet to the test station, cover or integrated control station.

The articles maintain their parameters at operating temperatures from 0°С to 45°С, if installed in soil below freezing point.
