The BI METAL LUGS are the top choice when it comes to connectors designed for electrical use. They have been created for breaking the ice between aluminium conductors and copper cables, busbars or devices. Using two different metals, usually, an aluminium barrel and a copper palm, they are produced and through advanced processing like friction welding, permanently bonded. This metallurgical bond provides not only good electrical characteristics but also high-mechanical strength-and-long-term-reliability.

The first and foremost reason why BI METAL LUGS are there amid us is the difficulty of directly connecting aluminium cables with copper parts. The problem here espouses from the fact that aluminium and copper have opposite electrochemical characteristics and as a result of direct contact between them corrosion (specifically galvanic) would occur, which is even more pronounced in the presence of moisture. This corrosion would cause resistance at the contact point to rise, produce heat and lose connection eventually leading to fire hazards. Bi-metal lugs remove this risk through establishing a secure transition between the two metals.

One more plays a big role in when talking about one of the key benefits of BI METAL LUGS and that is the thermal expansion control. Out of the two, aluminium grows fatter more than copper does when they both carry the current. If nothing is done or not properly taken care of, in the long run, this difference will be responsible for the joint to become loose. Bi-metal lugs are designed in such a way that the difficulties caused by these variations are shelved off hence maintaining a tight, low-resistance connection even in conditions with fluctuating loads. This feature makes them particularly suitable for applications where high current is involved and also continuous-duty operations.

In the practical world, you cannot miss BI METAL LUGS in cabling connecting power distribution panels, transformers, switchgear, substations and even industrial control systems. Plus, the roles they play in renewable energy installations such as solar and wind power systems where they are becoming more and more important for handling and cutting costs and weights as well as for elctrical equipment maintenance, are totally undeniable as those areas have aluminium cables as the primary choice due to their lower cost and lightweight nature while for copper terminals, it is still equipment-standard.
