ALEF (Aluminium Electric Force)

The specially developed material ALEF is a high-performance aluminium composite material characterised by high conductivity, high mechanical resistance and excellent anti-corrosion properties. Components made from ALEF have been assessed in connection with copper and aluminium conductors pursuant to the following standards:

  • EN 61439-1:2011
  • EN 61439-3:2012
  • EN 60998-1:2004
  • EN 60998-2-1:2004
  • EN 60068-2-30:2005
  • EN 60068-2-11:1999
  • EN 60068-2-6:2008
  • EN 60068-2-27:2009
  • OVE-Richtlinie R21:2019-02-01
  • DIN VDE 0603-3-3:2020-08
  • IEC 61545:1996

International approvals

As a material, ALEF superbly meets the requirements set out in the standards and in doing so reduces electrical power loss compared with conventional connection clamps by up to 51%. Moreover, this high-performance aluminium composite material has several international approvals.
