Crimping tools should checked before
starting work, avoid the risk injury
and ensure good result.
Damage and/or contamination tool
parts can lead deterioration the
end result and shortened tool life.
A good cable stripper guarantees clean
stripping without damage individual
strands, follow Elpress instructions for
stripping lengths.cenelec.iec.
For type testing electrical terminals,
the current standard IEC 61238-1-1, it
supersedes all national standards. This is
rarely problem they are likely be
used installations the same age.
The crimp dies are the key success-
ful crimping process, whether they are
hydraulically manually operated.
The Standards are established mainly
through international and European
collaborations within the International
Electrotechnical Commission (IEC) and
CENELEC (Comite’Européen Normali-
sation Electrotechnique).
It very important that all tool parts are
kept dry and clean and that they are
regularly checked for damage.
In newer installations with higher
demands current and temperature, it
is important choose materials tested
according current standards.12:3

Tests against standard
Many existing products for electrical
terminals are older than IEC 61238-1-1,
this does not mean that they have be
retested against the new standard to
be acceptable, the standard they were
tested against launch applies. SEK represents
and coordinates Swedish companies and
authorities.

These standards are available the SEK
website. There are also manuals that
show regulations and recommendations
for different types installations.

In addition this, there are large
number more industry-specific
standards for railways switchgear
where, addition the requirements of
IEC 61238-1-1, there may need for
vibration and environmental testing.
Crimp results
For good crimp result, you have to
ensure clean conductor surfaces, without
visible oxide layers.se/
