Galvanic corrosion occurs between two metals with different oxidation potentials, such as steel and copper. However, other conditions are also required, thanks to which Apliweld® Secure+ aluminothermic welding does not oxidise the corrugated steel to copper cable connection.
Exothermic welding, also known as aluminothermic welding, is the result of a process that achieves the molecular union of two or more metallic conductors through a chemical reaction. If it is performed correctly, it results in a bond that is superior in conductivity and durability to any that is carried out mechanically. To obtain this, it is vital to follow certain criteria that determine the quality of the welding.

Earthing is a fundamental step in any electrical system installation. Its proper installation also depends on the proper functioning and safety of equipment and people, as it protects against potential differences that can be dangerous in both cases. Why it is so vital, how to set up a project correctly and what regulations must be followed to install the earthing system of a lightning conductor are some of the main questions answered by Aplicaciones Tecnológicas.
