Lukas Anlagenbau GmbH is a family owned company,
established in 1959, that produces customer-specific
equipment for the wire and cable industry.
The focus of our products is complete taping lines
for producing taped or wrapped conductors with tape
materials like PTFE, Kapton, Mica, Paper, etc.
We also produce special cables for medical and
aircraft applications, our taping lines can be found at
many well-known suppliers worldwide.
Furthermore our product range covers single
components like pay-offs, capstans, caterpillars and
take-ups, up to complete rewinding lines and fine wire
drawing lines for non-ferrous materials.
During recent years our development has been
advanced by a focus on energy and size reduction.
At this year’s wire show we answer this request
with new components that are intended to solidify
our top position in taping machines for magnet wire
applications and to extend our business in the cable
industry with cost-optimized and easy-to-integrate
taping and heating solutions.
This should make our products more competitive
especially to the Asian market.
At our newly designed and enlarged booth 12B22
we are looking forward to meeting new and existing
customers.

Sikora is launching its new models of
the Purity Concept systems. With that, the
company offers an outlook on the varied
potential of its systems for online and
offline inspection and analysis of plastic
material. According to the application,
the systems are equipped with X-ray
technology (X), infrared technology (IR)
or optical sensors (V) and can be used for
samples during production in order to
find impurities from 50μm.
Especially interesting are the systems for
the production of high voltage cables. An
essential criterion of high voltage cables is
the production over long distances with
as few joints as possible. Various factors
make the production of a cable in one
length sometimes impossible to realise.
In this case two cable ends have to be
connected to each other in order to cover
larger distances.
In order to connect two cables with
each other, the ends have to be stripped
first. Both blank conductors are welded
together. The occurring gap in the
insulation is closed by manually applied
layers of tape. Thereby, it is essential
that the tape does not contain any
contamination, which might later cause
breakdowns of the cable. However, for all
the care, there might be contamination
that is not visible with the naked eye –
metallic and organic contamination from
50μm in the tape.
The Purity Concept systems with optical
sensors are suitable for the inspection and
analysis of thin, transparent films/tapes.
The systems with X-ray technology are
appropriate, for example, for thick, black
tapes1. In this way, it can be ensured that
the same quality as used for the main
insulation is used during the production
of the tapes.
Films and tapes for the insulation of joints in
the high-voltage cable area are produced by
using the same high quality XLPE 2 material
that is used for the insulation of the cable.
This brings some logistic challenges with it.
Tapes are coiled when they are sent out by
the manufacturer and need, therefore, to
be delivered and used before they get cross
linked by environmental circumstances.
Therefore, a stockpiling order is just as
problematic as possible delivery delays.
A possible solution is the independent
production of films/tapes at the manu-
facturing site. By using an extruder,
the tapes can be extruded. The used
XLPE material can either be inspected
for contamination from 50μm prior
to entering the extruder by the Purity
Scanner, or after the extrusion by the
Purity Concept system.
1 Used films/tapes are often thin
enough that they can be inspected
with both the X-ray technology and
the optical sensors
