Product overview

Elpress AKS Transition Joints of Al to Solid Cu Conductors

Elpress AKS Through Connectors of Al (16-95mm²) to Solid Cu Conductors (10mm²) are transition joints used for connecting Stranded Aluminium Conductors to Solid Copper Conductors. Two crimps are needed for both Al (crimp sequence see image below).
Part Numbers: AKS16-10S, AKS25-10S, AKS35-10S, AKS50-10S, AKS70-10S, AKS95-10S.

General Information

SYSTEM ELPRESS
System Elpress consists of Terminals and Tools designed and tested together to give a certified crimping result. This ensures that users will feel confident when using our systems, and the achievement of a secure connection through the proper handling of our products. By using Elpress Cu-Connection elements together with one of Elpress Crimp Systems one obtains a connection tested according to the requirements of IEC 61238:1.

AL TERMINALS
Elpress Terminals and Lugs for Al cable made of solid and 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) manufactured from solid materials, friction-welded together, joining Aluminium with Copper. To achieve that, the Al part rotates against the Cu part under pressure. This method provides the best connection between Al and Cu.

Crimping & Marking

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, note that there is an area difference between stranded and solid Al Conductors (see tables). When using sectoral Al-cable, a pre-rounding is normally necessary, done with a round crimping tool. When contact crimping Al Terminals, always make two crimps. 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.
