AlCu terminals

We produce the terminals with friction welding, which means that aluminium is joined with copper. This is done when aluminium is rotated towards copper under pressure and it is the method that provides the best bond between Al and Cu. We produce AlCu terminals of type AKK, AKS and AKP, but also largely customised terminals (also larger than 1200 mm²).

• Terminals of type AKK are used at the end of an Al conductor for connection to a Cu bus bar.
• Through connectors of type AKS are used for jointing of Al conductors to Cu conductors.
• Pin sleeves of type AKP are made for connection of Al conductors to apparatus with connections of copper.
• Transition through connectors of type AKS-10S are used for jointing stranded Al conductors to solid Cu conductors 10 mm² (e.g. Excel, Excelett)

Marking and number of crimps

The AlCu terminals are marked with logotype, conductor area for stranded and solid conductors and reference to round crimping tool and crimping tool in the Elpress product range. On the through connectors, a tool reference is also given for hexagonal crimping of copper.
When an adequate crimping is done with the right tool, Elpress' dies makes an impression on the sleeve so that all connections can be checked afterwards.
In the tools, there is a built-in full closure system that ensures that the entire crimping process is completed - a prerequisite for professional and quality-assured work. When crimping, two crimps are always done on the Al part and normally 1-2 crimps on the Cu part. Check the number of crimps recommended on the package label before crimping is done.

Customised products

Upon requests for variants in hole arrangement, the size of the connection flag and the like, we make variants of cable clips. Read more on our page about Consulting.
