High frequency
connector range
Johnson®, a subsidiary of Emerson
Network Power Connectivity Solutions,
has introduced a line of SMP Blind-Mate
connectors that can handle frequencies
up to 40GHz. This precision connection
interface is a micro-miniature, slide-on/
snap-on interconnect system designed
for high-density packaging. The system
is extremely flexible since it can correct
axial and radial misalignment and is
compatible with all SMP and GPO®
connectors.
Johnson offers several configurations of
its SMP Blind-Mate connector to meet
a variety of needs in high frequency
applications. Johnson’s new line of
SMP Blind-Mate connectors includes
26 different connectors, adapters and
mounts and nine new assembly tools.
The company also provides detailed
assembly instructions and makes use
of industry standard tooling whenever
possible for customer convenience and
compatibility.

Absolute cleanliness is essential in
high-voltage cable production. With the
CSS 2 for real time control and detection
of contamination in the polymer melt,
Sikora believes it can offer the technology
to guarantee process stability and product
quality at the production line.
The CSS 2 camera system detects
contamination particles in XLPE-materials.
With super clean PE-material, higher
voltage insulation strength with identi-
fiable wall thicknesses and no defect
charges can be achieved.
Contamination can be caused by material
handling. Shavings can be created by
wear of the extruder screw or the cleaning
of the extruder screw can leave dust
particles that bring tiny pores or inclusions
into the material.
Contamination in the form of combustion
particles such as amber and scorches,
which occur during the long-term
operation of the line, are also a risk.
The CSS 2 system ensures real-time, online
quality assurance, removing the need for
time-delaying laboratory analysis. 100%
inspection of the XLPE-melt in the flow
channel allows immediate intervention
in the production process. The flow
channel between the extruder and the
crosshead includes sight glasses and
an optical CCD-camera system, which
transilluminates the insulation material.
The CCD-colour camera detects particles
of 20µm in the PE-melt and the identified
constituents are classified with regard
to their size. Particles that exceed the
specified tolerance value are analysed
and their colour, situation, vertical and
horizontal dimensions are displayed.
Besides the graphical display of the
detected particles, monitor pictures show
a live image of the complete material flow.
In contrast to granulate control the system
actually detects contamination in the
material before the cable is produced.

Cleanliness in high-voltage cable production
Rod dry cleaning
and preparation by
the DCCD system
enables in-line
direct drawing of
mechanically de-
scaled high and
low carbon rod, up
to 0.88%C, without
wet pre-coating
chemicals and with-
out rod speed limitation. The process
incorporates the new LVC/PDH rod
dry coating technology that enables
an automatically controlled fusion of
lubrication compounds.
Such a liquefied substance eliminates
completely traditional wet pre-coating
chemicals and provides an adherent and
consistent residual coat, automatically
adjustable in weight at all speeds.
The DCCD processed 5.5mm (0.218")
0.83%C rod is dry coated and drawn
directly, in-line, without wet pre-coating,
to 1.85mm (0.073") at 13.5m/s (2,700ft/
min) with virtually zero friction - exiting
wire temperature not exceeding 45°C.
A recent application of the DCCD
process is for 5.5mm (0.218")
0.78–0.85%C rod, dry cleaned and
surface prepared in the first draft,
in-line, with zero consumables cost
and with virtually zero energy
consumption, with an output of
2.2 tons/hour.
The system offers immediate substantial
cost savings in production of quality
wires, including spring, rope, bead,
PC strand and galvanised H/C or L/C.
