Hot-dip tin-plated continuous casting copper-clad steel earthing bar/rod/electrode  


Working principle

When most of the metal contact various kinds of solutions, it will be automatically corroded; the metal coverts to metal ions and enters into the solution and corresponding electrons will be left on the metal surface; the more ions enter into the solution, the more electrons will be left on the surface; ionization of metal will become more and more difficult because of the attraction between negative electrons and positive ions and finally equilibrium will be realized, as shown in the equation below:

In different solutions, different metal has different ionization tendencies or degrees. When ionic equilibrium is reached, it means that metal establishes an equilibrium (electrode) potential in the solution according to electrochemistry terminology. The metal becomes an electrode in the solution and electrode potential and free energy also can express the spontaneous tendency of corrosion: high potential indicates that the ionization is not easily realized, for example, precious metal such as gold, silver, copper, etc.

The composite coating is made of tin which guarantees anti-oxidation without influencing cathodic protection; the inner layer is made of oxygen-free copper which guarantees anti-oxidation and excellent conductivity property.
The composite matrix metal adopts high-quality carbon steel to guarantee high strength and good magnetic permeability.
It is manufactured via continuous casting technology and combination of copper-clad steel metallurgic molecules to avoid electrochemical corrosion and galvanic effect. 
With copper layer thickness≥1.0mm, it complies with UL467 and relevant standards of the state.
Service life is longer than four decades.
