How do bi-metallic lugs prevent galvanic corrosion?
The use of BI METALLIC LUGS is one of the methods that can prevent galvanic corrosion at its worst when connecting aluminium conductors to the copper busbars or terminals. When metals of different kinds are in contact with each other, an electrolyte is present, and the less noble metal is extensively eroded. In the case of electrical systems, the result may be not only loose connections, but also increased resistance, overheating, and failure of the entire system.

With BI METALLIC LUGS, this risk is eliminated as they are made with a friction-welded bond joining the copper palm and the aluminium barrel. The welded area acts as a junction that is both stable and permanent and thus does not allow chemical reactions between the two metals. The aluminium conductor gets crimped into the aluminium barrel while the palm that is connected to copper terminals ensures that only copper and aluminium are not in direct contact.

PIONEER POWER INTERNATIONAL is one of the manufacturers that guarantee first-rate production standards by applying modern bonding methods that keep the conductivity and the structural integrity of the product at a high level. In addition, their BI METALLIC LUGS come with surface treatments that offer protection and increase the resistance levels moisture, oxidation, and environmental contaminants which in turn lowers corrosion risks.

With the installation of BI METALLIC LUGS of PIONEER POWER INTERNATIONAL, the users can be assured of getting maintenance free, stable and corrosion-free connections for a long time in power distribution, industrial panels, and renewable energy systems.
