The icotek range of cable entry products available from
M Buttkereit Ltd has been extended with the KEL-BES range.
These products feature polyamide frames incorporating
entrapped polyamide brushes, providing a quick and simple
push-through entry for routing cables into network cabinets
and control boxes.
The KEL-BES products are also suited to exit/entry apertures in
the raised floors utilised within computer centres.
Three frame sizes are currently available, all providing exact
matches for the cut-out dimensions applicable to 10-, 16- and
24-pole standard industrial connectors.
All frames feature a 10mm-thick projection above the
mounting service, with a wide mix of round, flat and even
pre-terminated cabling being accommodated.
The twin brush strips incorporated into each frame provide a
self-sealing closure to whatever standard or mixed cabling is
utilised, so limiting or preventing the ingress of all but very fine
dust particles.
All frame fixing and cable routing applications can now be
simplified, resulting in higher versatility and time saving.
The frames are manufactured from black polyamide with a
flame class of UL94-Vo, with the same material utilised for the
brushes. The products are halogen- and silicone-free and are
suitable for operations within a temperature range of -20°C to
+90°C.

PAI enamel in thermal class 240°C
The need to complete the IEC Regulation for the use of
enamelled wires for electronic purposes has resulted in the
establishment of a new standard for the production of high
thermal class enamelled wires.
This new standard was necessary in response to the
restrictions demanded by the REACH Regulation, which no
longer allows large quantities of polyimide enamels (PI) to
be imported from countries outside Europe and strongly
regulates the NOx gas emissions for minor solvents content.
For this reason, in 2012, Elantas decided in agreement with
the Italian corporation Comitato Elettrotecnico Italiano CT
55 to create a new standard regulating the use of enamelled
wire made with polyamide-imide enamel (PAI) in thermal
class 240°C.
By then, Elantas Italia had already developed a PAI enamel in
thermal class 240°C that satisfied the requirements set by the
only standard for high thermal index (IEC 60317-46 Aromatic
polyimide enamelled round copper wire, class 240).
The product Allotherm 602 BGM was proposed as a definite
alternative enamel. The application of PAI enamel helps
reduce NOx emissions to 40 per cent. Allotherm 602 BGM
also has a longer molecular stability than PI enamel, resulting
in good usability without any particular storage problems.
The new standard publication was completed in April 2015
under the guidance of project leader Gino Paolo Piccioni,
technical assistance manager, in the space of three years.
