From Talleres MAF we tell you what bimetallic connectors are and what they are for. We are manufacturer of electrical material since 1985; we want you to know a key element in the medium and high voltage electrical distribution sector. Today the industry has developed so much that we use a thousand and one components to manufacture our products or assemble our installations; and above all, when it comes to electrical components, quality is essential to avoid serious complications.

What are bimetallic connectors?


Bimetallic connectors are a type of electrical material used to connect cables and consist of two bodies, one made from bronze and the other from aluminium, guaranteeing their conductivity.


What are bimetallic connectors used for?


And you may ask yourself, why do we give so much importance to this type of connector by dedicating an exclusive blog article to it? What is a bimetallic connector for? Well, the truth is that these types of connectors have made life much (if not very) easier for workers and companies in the field of electricity.

Both bronze and aluminium are two of the most commonly used materials in the manufacture of electrical material, due to their excellent properties. And they are the ones we use in Talleres MAF to manufacture our bimetallic connectors.

On the one hand, copper is very ductile and malleable, as well as ultra resistant to rust and the passage of time. On the other hand, aluminium is lightweight and very resistant to corrosion, as well as being recyclable (which adds up to a lot these days) and an excellent conductor of electricity.

So, with these two materials being so widely used together, it was necessary to have a connector that made it possible for them to work together. And this is where the bimetallic connector came in, as it allows for copper-aluminium connections or vice versa.


Advantages of bimetallic connectors


These are the main advantages of bimetallic connectors:

  • They guarantee conductivity between aluminium and copper.
  • They avoid the galvanic couple (the corrosion that usually affects the connectors).
  • The work becomes easier and without so many complications.
  • To improve the properties of the bimetallic connector, it is enough to apply inhibiting grease. Thus, corrosion is greatly avoided and conductivity is improved.

As you can see, the advantages and applications of bimetallic connectors are numerous, so do not hesitate to apply them to your installations or medium or high voltage electrical projects.
