Elpress AKS AlCu Bimetallic Through Connectors (16-400mm²) (AKS50-95, AKS120-120, AKS185-120)

Product overview

Elpress AKS AlCu Bimetallic Through Connectors

Elpress AKS AlCu Bimetallic Through Connectors (16-400mm²) are used for connection of Al to Cu conductors. Stranded/solid Al conductors, stranded/multi-stranded Cu conductors. For multi-stranded Cu conductors, contact crimping using the Dual system is recommended. Two crimps are required for Al (see image below), normally one for Cu. When hexagonally crimping the Cu part, the dies are placed between the marking groove and the outer edge.
Popular Part Numbers: AKS50-95, AKS120-120, AKS185-120.

General Information

SYSTEM ELPRESS
System Elpress consists of Terminals and Tools that are designed and tested together to give a certified crimping result. This ensures that users will feel confident when using our systems, and that a secure connection is achieved through the proper handling of our products.

AL TERMINALS
Elpress Terminals and Lugs for Al cable are made from pure aluminium 99.7%. We manufacture Al Terminals of type AK and AS, but also customised terminals or terminals larger than 1200mm2.

ALCU TERMINALS
Elpress Bimetallic Terminals (AlCu) are manufactured from solid materials, which are friction welded together, joining Aluminium with Copper. This is achieved when the Al part is rotated against the Cu part under pressure and is the method providing the best connection between Al and Cu.

Elpress Crimp Sequence Aluminium

NUMBER OF CRIMPS
The Elpress system is suitable for both Stranded (acc. to IEC 60228 Class 2) and Solid Conductors (acc. to IEC 60228 Class 1). However, it should be noted that there is an area difference between stranded and solid Al Conductors (see tables). When using sectoral Al-cable, a pre-rounding is normally required, which is done with a round crimping tool. When contact crimping Al Terminals, two crimps should always be made. Note the crimp sequence.

MARKING OF AL & ALCU LUGS
Elpress  system for marking Al and AlCu Terminals shows the conductor area and reference to rounded and contact crimping tools, within the Elpress range. A tool reference for hexagonal crimping copper is give on the bimetallic through connectors.
