Conductors for overhead lines
Greenpas cables
, manufactured by
Tele-Fonika Kable, feature a three-layer
insulation structure.
The core wire is a conductor of an alloy
of Al-Mg-Si, sealed with a special swelling
powder serving as a barrier to prevent
longitudinal migration of moisture. A semi-
conducting layer is responsible for the
uniform distribution of the electric field.
A further insulating layer is a thermoplastic
polyethylene LDPE.
The outer casing is made of thermoplastic
HDPE, immunized to UV radiation and
weathering. The use of thermoplastic
polyethylene enables full recycling of the
materials after use.
Compared to traditional PAS wires (with
one layer of insulation) Greenpas cables
are characterized by higher insulation
resistance and insulation resistance to
partial discharges and sliding discharges.
The wires are more robust than PAS wires,
and provide a longer period of safe
operation.
Enkotec on show
Enkotec
demonstrated three nail
manufacturing lines at its booth at
wire Düsseldorf this year:
ENKOnail+ is a new NI02 machine, the first
of the ENKOnail+ machines to appear in
an upgraded version with release later
this year. The upgrade includes features
such as the disco variator replaced by a
robust and maintenance-free servomotor
drive, a new improved system for insertion
timing, larger feed rollers with longer life,
and exhaust air connections for efficient
dust evacuation. The six PLC-controlled
ENKOnail+ machines produce up to 2,000
nails per minute.
Also on show was a high-speed
in-line nail manufacturing line with
an ENKOnail+NH01 nail machine for
manufacturing short nails of 1.8–2.87mm
diameter and 32–65mm length. The
machine on display was set up with the
ENKOroll thread-rolling machine, type
TA01, designed for making screw shank
or annular nail profiles with a production
speed of up to 2,500 nails per minute.
Finally, the ENKOnail machine, type MI01,
for the production of nails of 2.3–3.8mm
diameter and 50–90mm length at a speed
of 1,000 nails per minute. The MI01 model,
intended for small and midsize capacity
needs, features a more mechanical
adjustment set-up than the high-capacity
ENKOnail+ series.
Heated fabric using carbon nanotube
coated fibers
Kuraray Living
has developed a heating
fabric using CNTEC, a carbon nanotube
coated electro-conductive fiber. The fiber
was co-developed with Hokkaido University
and others.
“This product uses conventional technology
for the polyester fibers, and carbon
nanotubes, a cutting-edge material, as
a coating for the fibers. The fibers are
woven into a textile, and when electricity is
passed through them, they give off heat,”
a spokesman revealed.
The nanotubes are applied using
conventional dye-printing technology,
with a carbon nanotube network forming
on the surface of every filament in the
multi-filament structure. The resulting fabric
is thin, lightweight, flexible and soft, and
has a high level of washing durability. It
recently won an award from the Japanese
Ministry of Trade, Economy and Industry.
Suggested uses for the fiber include
USB-powered tabletop heaters and heated
cushions as well as heated car seats and
carpets. By taking advantage of the fact
that the whole surface heats up uniformly,
Kuraray is also developing a waterproof
snow-meltingmat. The technology continues
to be field-tested by Hokkaido University.
New 120 Gbps active optical cable
Emcore Corp
is sampling a 120 Gbps
CXP active optical cable to customers.
Designedfor high-performancecomputing
and high-end ethernet router and switch
applications, the 120 Gbps CXP is the latest
in Emcore’s Connects Cables line of high-
speed active optical cables.
Emcore’s 120-Gbps CXP active optical
cable is a high-density, low-weight,
edge-mounted, bidirectional interconnect
that can reach up to 100m with what the
company describes as an “exceptionally
low” bit-error rate. This equates to
significantly less performance degradation
over longer distances, compared to
traditional copper cables.
The CXP active optical cable is also over
60 percent lighter, with a bend radius said
to be 70 percent less than 26-AWG copper
cables. The combination of lower weight,
smaller bend radius, and the flexibility
of the cable make it easier to install,
maintain, and repair cluster cabling
without straining server connectors, or
affecting neighboring cables, the company
says. The Emcore CXP active optical cable
is hot-pluggable and fully compliant with
the CXP multi-source agreement (MSA)
and RoHS 6/6.
“Our 40-Gbps Quad Data Rate (QDR)
cables are currently deployed in two of
the top five supercomputers in the world,”
commented Jaime Reloj, Emcore’s vice
president of business development.
“By leveraging our next-generation
vertical-cavity surface-emitting lasers
(VCSEL) and photodetectors, we will
continue to advance the technology for
high-performance computing applications.”
Software for metal forming
Metal Forming Systems
develops and
supplies process design and finite element
analysis (FEA) simulation software for the
metal forming industry. The company’s
software products include ‘Nagform’
for the design of forming sequence and
‘Nagsim.2D / Nagsim.3D’ for the simulation
of forging processes by the finite element
method.
