Elpress Bi-Metallic AlCu-terminals
Elpress Al/Cu terminals for Al-conductors are made of solid
material. We produce the
Elpress terminals using friction welding, which means that
the aluminium is joined to the copper. This is done by rotating
the aluminium while in contact with the copper under pressure,
which is the method that provides the best bond between
aluminium and copper. We manufacture type
Elpress AKK, AKS and AKP S Al/Cu-connectors, but also many
customer-adapted terminals (including some larger than 1200
mm˛).
* Type
Elpress AKK terminals are used to terminate Al-conductors at
Cu bus bars.
*
Elpress AKS type through connectors are used for joining
Al-conductors to Cu-conductors.
*
Elpress AKP type pin sleeves are manufactured for connecting
Al-conductors to apparatus with copper terminals.
*
Elpress AKS-10S type transition through connectors are used
for joining stranded Al-conductors to solid 10 mm˛ Cu-conductors
(e.g. Excel, Excelett).
Markings and number of crimps
Elpress Al/Cu-terminals are marked with a logo, conductor
cross-sectional area for stranded and solid conductors, and
references to pre-forming and crimping tools within the Elpress
range. The tool reference for hexagonal crimping of copper is
also stated on through connectors.
When crimping is completed with the correct tool, the Elpress
dies and punches stamp the sleeve so that all connections can be
checked afterwards.
Except for the hobby tools, there is a built-in full closure
system which ensures that the complete crimping procedure has
been performed – a condition for ensuring a professional and
high quality job. When crimping, two crimps are always performed
on the Al-section and usually only one on the Cu section. Check
the recommended number of crimps (see the pdf file Hydraulic
crimping system, below) before crimping.
