General Information

Elpress Al Terminals and Connectors are made from pure aluminium 99.7%. We manufacture Al Terminals AK, Al Through Connectors AS with partition, Al Through Connectors AS with partition and for different areas and Al Through Connectors AS without partition. The standard size is 16 to 1200mm² but a variety of customer specified types also exist.

Elpress AlCu Terminals and Connectors for Al cable are made from solid materials with friction welding. This method joins aluminium and copper material, when the aluminium part is rotated against the copper part under pressure and is the method providing the best connection between Al and Cu. We manufacture AlCu Bimetallic Terminals AKKAlCu Pin Bimetallic Terminals AKPTransition Connectors AKS for Al Conductors to Cu solid ConductorsAlCu Bimetal Through Connectors AKS and AlCu Bimetallic Through Connectors AKS.

Elpress marking system for marking of Al and AlCu Terminals and Connectors shows the stranded and solid metric conductor size and reference to the id-numbers of the appropriate Elpress pre-rounding and crimp tools. Do not use other crimp tools! The T2-mark is a reference to an earlier Finnish standard. On bimetallic connectors there is also a tool id-reference to the hexagonal die to be used for the Cu-crimp.

In cases where other hole patterns, palm sizes, assembly angles, etc. are needed, a broad variety of customer specified items may be produced. Some examples are indicated here: AKK500A/2-16-12×4-35 resp. AK185-14×2-40.
