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.

• Al Terminals type AK used with Al conductors for connection to busbars and apparatus sockets.
• Al Through Connectors type AS used when connecting Al Conductors.

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.

• Terminals of type AKK used at the end of an Al conductor for connection to a Cu bus bar.
• Through Connectors of type AKS used to connect Al Conductors to Cu Conductors.
• Pin Sockets of type AKP used to connect Al Conductors to apparatus intended for Cu Pin Connections.

Crimping & Marking

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.
